A
Ante Bet (Double Chance) (Aposta Ante, Apuesta Ante, Анте-ставка (Double Chance))
Slot Mechanics & Engine Features
An optional surcharge added to the base wager (typically +20% to +25%) that artificially increases the mathematical probability of triggering bonus scatters.
Example: Turning on the 25% Ante Bet on a $1.00 stake increases the cost per spin to $1.25, adding extra scatters to the virtual reel strips.
Autoplay Limits (Limites de Autoplay, Límites de Autojuego, Лимиты автоигры (Autoplay))
Slot Mechanics & Engine Features
Mandatory responsible gaming settings in slot interfaces requiring players to set explicit stop-loss and single-win thresholds before initiating automated spins.
Example: Configuring autoplay with a $50 stop-loss limit ensures that the game engine instantly terminates automated spins the moment net losses touch $50.
B
BMM Testlabs (BMM Testlabs, Laboratório BMM, Лаборатория BMM Testlabs)
Regulations, PRNG & Player Safety
The world's longest-established private independent gaming testing laboratory, providing compliance testing and RNG certification across 400+ jurisdictions.

Bust Rate (Taxa de Quebra, Tasa de Quiebra, Bust Rate (доля банкротств))
Volatility & Variance Dynamics
The empirical percentage of simulated or observed gaming sessions that terminate with total bankroll depletion prior to hitting a designated target.
Example: In Monte Carlo simulations of 500 spins with a 100-bet bankroll on high-volatility slots, the bust rate regularly exceeds 65%.
C
Cascading Reels (Tumbling) (Rolos em Cascata, Caída en Cascada, Каскадные барабаны (Tumble))
Slot Mechanics & Engine Features
A mechanism where winning symbols disappear from the grid and new symbols fall from above into empty spaces, enabling multiple consecutive wins from a single paid spin.
Example: In Gates of Olympus, a single spin can trigger 6 successive cascades, accumulating multipliers and payouts without charging additional bets.
Cluster Pays (Pagamentos em Cluster, Pagos por Grupo, Кластерные выплаты)
Slot Mechanics & Engine Features
A game engine mechanic where payouts are triggered by groups of matching adjacent symbols touching horizontally or vertically anywhere on a grid.
Example: In Sweet Bonanza or Sugar Rush, clusters of 8 or more matching symbols pay instantly and trigger a tumble mechanism.
Confidence Interval (CI) (Intervalo de Confiança, Intervalo de Confianza, Доверительный интервал)
RTP & Probability Math
The mathematical range within which an observed session RTP is expected to fall with a specified probability (typically 90%, 95%, or 99%).
Example: After 10,000 spins on a 96.5% RTP slot with σ = 8, the 95% confidence interval is 96.5% ± 1.96 × (8 / √10,000) = [80.8%, 112.2%].
Cryptographically Secure PRNG (CSPRNG) (CSPRNG, PRNG Criptograficamente Seguro, Криптографический ГСЧ)
Regulations, PRNG & Player Safety
An advanced class of PRNG that satisfies rigorous cryptographic unpredictability standards, rendering next-state prediction impossible even with past outputs.
Example: Certified providers use algorithms like ChaCha20 or AES-CTR with hardware entropy, ensuring that external predictor bots have zero predictive power.
Curacao eGaming License (Licença de Curaçau, Licencia de Curazao, Лицензия Кюрасао)
Regulations, PRNG & Player Safety
A prevalent offshore regulatory framework authorizing international online gambling platforms under master licenses (8048/JAZ, 1668/JAZ, 5536/JAZ, 8048/JAZ2018).
Example: Operators like 1win and Stake run under Curacao jurisdiction, offering global crypto and fiat rails, but with limited state-level consumer arbitration.
D
Dead Spin (Giro Seco, Tirada en Blanco, Пустой спин)
Volatility & Variance Dynamics
A wagered spin that returns exactly zero credits, resulting in a 100% loss of that individual bet.
Example: In slots with a 20% hit frequency, the mathematical probability of experiencing a streak of 15 consecutive dead spins is (0.80)^15 ≈ 3.5%.
Drawdown (Maximum Drawdown) (Rebaixamento, Caída de Saldo, Просадка (Drawdown))
Volatility & Variance Dynamics
The peak-to-trough decline in a player's bankroll during a specific session or timeline, measured in currency units or percentage of peak balance.
Example: Starting with $1,000, rising to $1,400, and then falling to $600 represents an absolute maximum drawdown of $800, or a 57.1% drop from peak.
Dud Rate (Feature Buys) (Taxa de Dud, Tasa de Dud, Dud-rate (пустой бонус))
Volatility & Variance Dynamics
The mathematical probability that an expensive bonus buy round fails to return even a modest fraction (commonly < 0.25x or < 0.30x) of its purchase cost.
Example: In 100x bonus buys on extreme-volatility slots, the dud-rate commonly exceeds 72%, meaning nearly 3 out of 4 bonus purchases return under 25x.
E
eCOGRA (eCOGRA, Selo eCOGRA, Аудитор eCOGRA)
Regulations, PRNG & Player Safety
An independent UK-based testing and standards organization specializing in player protection, dispute resolution, and fair gaming certifications.
Example: An eCOGRA Safe and Fair seal indicates that an operator's payout reports are audited quarterly and that effective player mediation is maintained.
Entropy Pool (Pool de Entropia, Reserva de Entropía, Пул энтропии)
Regulations, PRNG & Player Safety
A hardware-collected repository of truly unpredictable physical data (e.g. thermal noise, clock jitter) used by gaming servers to continuously seed RNG algorithms.
Example: Gaming servers harvest thermal noise from server processors into an entropy pool to prevent deterministic pattern repetition.
Expanding Symbol (Book Mechanics) (Símbolo Expansivo, Símbolo Expansivo Book, Расширяющийся символ)
Slot Mechanics & Engine Features
A special symbol designated during bonus play that expands vertically to cover all positions on its reel and pays across all active lines regardless of adjacency.
Example: In Book of Dead, landing the chosen expanding symbol on reels 1, 3, and 5 causes all three reels to expand to 3 full stacks, paying 10 full lines.
Expected Value (EV) (EV, Valor Esperado, Valor Esperado EV, Математическое ожидание)
RTP & Probability Math
The anticipated average outcome of a wager or series of wagers over time, calculated by multiplying each possible payout by its exact mathematical probability.
Example: On a $1 spin in a 96.5% RTP slot, the EV is -$0.035. Every single spin has an expected mathematical cost of 3.5 cents.
F
Feature Buy (Bonus Buy) (Bonus Buy, Compra de Bônus, Compra de Bono, Покупка бонуса (Feature Buy))
Slot Mechanics & Engine Features
A button allowing players to bypass base-game spins by paying a fixed multiple of their base bet (commonly 100x to 500x) to trigger the bonus round instantly.
Example: Paying $100 for a 100x Feature Buy at a $1.00 base stake guarantees immediate entry into the free-spins round with an individual bonus-RTP setting.
G
GLI-19 Standard (Padrão GLI-19, Norma GLI-19, Стандарт GLI-19)
Regulations, PRNG & Player Safety
The internationally recognized technical benchmark published by Gaming Laboratories International specifying standards for interactive gaming systems and RNGs.
Example: Compliance with GLI-19 requires software to prove mathematical fairness, statistical randomness, game security, and audit trail retention.
H
Heavy Tail (Pareto Distribution) (Cauda Pesada, Cola Pesada, Тяжелый хвост (Heavy Tail))
Volatility & Variance Dynamics
A mathematical property of distributions where probabilities of extreme events decay more slowly than an exponential curve, creating rare but colossal outliers.
Example: Slot jackpot mechanisms follow heavy-tailed Pareto models, where a microscopic 0.0001% of spins generates over 15% of the game's total theoretical RTP.
Hit Frequency (Frequência de Acerto, Frecuencia de Acierto, Частота выплат)
RTP & Probability Math
The percentage of spins that yield any non-zero payout, regardless of whether that payout is smaller or larger than the original wager.
Example: A slot with a 28% hit frequency produces a winning spin roughly once every 3.57 spins, although many payouts will be partial losses (LDWs).
Hold and Win Mechanics (Mecânica Hold and Win, Hold & Win, Механика Hold and Win)
Slot Mechanics & Engine Features
A bonus game mechanic where coin or prize symbols lock into place on the grid, resetting a 3-spin respins counter with every newly landed symbol until grid fill or exhaustion.
Example: Landing 6 cash coins starts a respins game with 3 spins; every new coin resets the counter to 3 and awards credit prizes or jackpots.
House Edge (Casino Advantage, Vantagem da Casa, Ventaja de la Casa, Преимущество казино)
RTP & Probability Math
The mathematical profit margin retained by the casino on every wager placed, calculated as 100% minus the game's Return to Player (RTP).
Example: If a slot has an RTP of 94.0%, the house edge is 6.0%. On every $100 wagered, the casino retains an average of $6.00 in the long run.
I
iTech Labs Certification (Certificação iTech Labs, Certificado iTech Labs, Сертификация iTech Labs)
Regulations, PRNG & Player Safety
A globally recognized accredited testing laboratory that audits slot software, PRNG algorithms, and mathematics sheets for regulatory compliance and statistical randomness.
Example: A valid iTech Labs certificate verifies that a slot developer's RNG has passed Marsaglia diehard and NIST statistical randomness test batteries.
K
Kelly Criterion (Slot Inapplicability) (Critério de Kelly, Criterio de Kelly, Критерий Келли)
RTP & Probability Math
A formula used to determine optimal bet sizing in positive-EV games. In slots, because EV is strictly negative, the Kelly Criterion dictates an optimal bet of exactly zero.
Example: Since expected value is negative (EV < 0), applying Kelly f* = (bp - q) / b yields a negative result, proving mathematically that bet progression cannot beat slots.
Know Your Customer (KYC) (Verificação KYC, Know Your Customer, Верификация KYC)
Regulations, PRNG & Player Safety
Mandatory identity verification protocols requiring players to submit proof of identity, residential address, and payment method ownership before withdrawals.
Example: Licensed casinos require passport scans and utility bills to comply with international Anti-Money Laundering (AML) standards before clearing large withdrawals.
Kurtosis (Fat Tails) (Curtose, Curtosis, Куртозис (тяжелые хвосты))
RTP & Probability Math
A metric measuring the 'tailedness' of payout distributions. High excess kurtosis in slots indicates heavy tails, where extreme outliers account for a large portion of the game's RTP.
Example: In Nolimit City's San Quentin, high kurtosis means that a notable percentage of the total RTP is concentrated in rare 50,000x–150,000x jackpot events.
L
Law of Large Numbers (LLN) (LLN, Lei dos Grandes Números, Ley de los Grandes Números, Закон больших чисел)
RTP & Probability Math
The theorem stating that as the number of independent spins approaches infinity, the empirical return converges inexorably toward the theoretical RTP.
Example: Over 500 spins, your observed return might be 240% or 30%, but over 5,000,000 spins it will inevitably converge within 0.1% of 96.5%.
Lognormal Distribution Body (Corpo Lognormal, Cuerpo Lognormal, Логнормальное тело распределения)
Volatility & Variance Dynamics
The mathematical probability density function governing the vast majority (95%+) of typical base-game and modest bonus payouts in modern video slots.
Example: In bonus buy analytics, the bulk of non-jackpot payouts clusters tightly around a lognormal peak located far below the break-even 1.0x line.
Loss Disguised as a Win (LDW) (LDW, Perda Disfarçada de Ganho, Pérdida Disfrazada de Premio, Потери под видом выигрыша)
RTP & Probability Math
A spin outcome that pays less than the original wager (e.g. paying $0.40 on a $1.00 bet) while triggering triumphant visual and auditory celebration animations.
Example: Betting $2.00 and winning $0.60 results in a net loss of -$1.40, yet sensory cues induce a psychological feeling of winning, masking bankroll depletion.
M
Max Bet Rule (Regra de Aposta Máxima, Regla de Apuesta Máxima, Правило максимальной ставки (Max Bet))
Regulations, PRNG & Player Safety
A restrictive clause in casino bonus terms specifying a hard cap on individual spin stakes (commonly $5.00 or 10% of bonus balance) while wagering active bonus credits.
Example: Placing a $6.00 spin while working through a bonus with a $5.00 max bet rule violates terms, allowing the casino to legitimately confiscate all accumulated winnings.
Max Win Cap (Ganho Máximo, Tope de Ganancia, Кап максимального выигрыша)
Volatility & Variance Dynamics
The hard programmatic limit on the maximum payout permissible in a single game round, typically expressed as a multiplier of the base bet.
Example: If a slot has a 10,000x cap, hitting a win that would mathematically calculate to 14,000x will be forcefully truncated at exactly 10,000x.
Megaways Mechanics (Mecânica Megaways, Motor Megaways, Механика Megaways)
Slot Mechanics & Engine Features
A proprietary reel modifier engine developed by Big Time Gaming where each reel randomly displays between 2 and 7 symbols per spin, offering up to 117,649 ways.
Example: When all 6 reels expand to the maximum 7 symbols each, the total active ways to win reaches 7^6 = 117,649 ways on that single spin.
Multi-Tier RTP Configurations (RTP Range, Níveis de RTP, Versiones de RTP, Мультитировый RTP)
RTP & Probability Math
The software architecture where studios (Pragmatic, Hacksaw, Nolimit) release games with multiple certified RTP settings (e.g. 96.5%, 94.0%, 88.0%) selectable by the operator.
Example: Playing Gates of Olympus at 88.0% instead of 96.5% triples the casino house edge from 3.5% to 12.0%, costing an extra $850 per 10,000 spins at $1.
P
Paylines (Fixed Lines) (Linhas de Pagamento, Líneas de Pago, Линии выплат)
Slot Mechanics & Engine Features
Predetermined geometric patterns across slot reels upon which matching symbols must land from left to right to trigger an award.
Example: In a 20-fixed-payline slot, symbols matching on line 12 pay according to the paytable, while matches off-pattern produce no return.
Progressive Jackpot (Jackpot Progressivo, Bote Progresivo, Прогрессивный джекпот)
Slot Mechanics & Engine Features
A cumulative prize pool funded by shaving a small percentage (typically 1%–5%) from every wager placed across a network of linked slot games until won.
Example: Mega Moolah pools contributions from hundreds of casinos worldwide, seed-funding the Mega progressive jackpot at $2,000,000 minimum.
Provably Fair Technology (Provably Fair, Comprovadamente Justo, Технология Provably Fair)
Regulations, PRNG & Player Safety
A cryptographic algorithm utilizing client seeds, server seeds, and nonces with SHA-256 or HMAC hashing, allowing players to verify that round outcomes were not manipulated.
Example: On Stake Originals slots or dice games, players can hash their client seed with the unhashed server seed post-round to verify the exact PRNG outcome.
Pseudo-Random Number Generator (PRNG) (Gerador Pseudoaleatório, Generador Pseudoaleatorio, ГСЧ (PRNG))
Regulations, PRNG & Player Safety
The mathematical algorithm running on secure game servers that generates sequences of numbers mimicking true randomness to determine slot reel stops.
Example: The PRNG produces thousands of numerical values per millisecond; the exact millisecond you press 'Spin' locks in the numbers mapped to the reels.
R
Random Seed (Semente de PRNG, Semilla del Generador, Сид (Seed))
Regulations, PRNG & Player Safety
The initial numerical value or state injected into a PRNG algorithm from an entropy source, serving as the starting point for generating pseudo-random sequences.
Example: If a server PRNG re-seeds from unpredictable physical noise sources every millisecond, output sequences remain completely uncorrelated.
Reality Check Limits (Reality Check, Alerta de Tempo, Контроль времени (Reality Check))
Regulations, PRNG & Player Safety
An automated pop-up notification appearing at predetermined session intervals (e.g. every 60 minutes) summarizing elapsed time, net wagers, and profit/loss.
Example: A reality check prompt pauses the game after 60 minutes, displaying that you have spun 700 times with a net loss of $65, prompting you to exit or resume.
Return to Player (RTP) (Return to Player, Retorno ao Jogador, Retorno al Jugador, Возврат игроку)
RTP & Probability Math
The theoretical percentage of total wagered turnover that a slot game is mathematically calibrated to return to players across an infinite sample of spins.
Example: On a slot with 96.5% RTP, wagering $10,000 across 10,000 spins has a mathematical expected return of $9,650, representing an expected loss of $350.
Risk of Ruin (RoR) (RoR, Risco de Ruína, Riesgo de Ruina, Риск разорения)
RTP & Probability Math
The mathematical probability that a player will deplete their entire bankroll to zero before reaching a designated profit target or session stop condition.
Example: With a bankroll of 200 bets on an extreme-volatility slot without stop-loss rules, the continuous risk of ruin exceeds 82% over 2,000 spins.
S
Sample Size (Tamanho da Amostra, Tamaño de la Muestra, Размер выборки)
RTP & Probability Math
The total volume of independent spins analyzed. Due to high variance, slot statistics require immense sample sizes to reach statistical significance.
Example: To distinguish a 96.5% RTP slot from a 94.0% version at a 95% confidence level with σ = 8, a sample size of over 615,000 spins is required.
Scatter Symbol (Símbolo Scatter, Símbolo de Dispersión, Скаттер (Scatter))
Slot Mechanics & Engine Features
A non-linear symbol that awards payouts and triggers free spins or bonus rounds regardless of its position on the grid, without needing to land on paylines.
Example: Landing 4 Scatters anywhere on the 6x5 grid in Gates of Olympus triggers 15 free spins and awards an instant 3x total bet payout.
Self-Exclusion (Autoexclusão, Autoexclusión, Самоисключение (Self-Exclusion))
Regulations, PRNG & Player Safety
A formal responsible gambling tool allowing a player to request the irrevocable closure of their casino account for a designated period (e.g. 6 months to permanent).
Example: Activating self-exclusion bars login access and halts all promotional messaging, preventing impulsive session restarts during periods of vulnerability.
Session Variance (Variância de Sessão, Varianza de Sesión, Сессионная дисперсия)
Volatility & Variance Dynamics
The statistical variance experienced over a short, finite window of spins (e.g. 500 to 2,000 spins), where results diverge heavily from long-term mathematical RTP.
Example: While long-term RTP is fixed, session variance allows for rapid doubling of bankroll or catastrophic 80% drawdowns within 40 minutes.
Skewness (Assimetria, Asimetría, Коэффициент асимметрии)
RTP & Probability Math
A statistical measure of the asymmetry of a slot's payout distribution. Slots exhibit extreme positive skew, with vast numbers of small losses and rare gigantic multipliers.
Example: Because slot distributions are heavily right-skewed, the median session outcome is significantly worse than the mathematical average outcome.
Slot Bankroll (Bankroll, Saldo de Jogo, Presupuesto de Sesión, Слотовый банкролл)
RTP & Probability Math
Dedicated, segregated recreational capital set aside solely for slot gameplay, completely separated from living expenses and governed by mathematical bet-sizing rules.
Example: A dedicated $500 bankroll divided by a 300-spin reserve rule establishes a maximum base bet of $1.66 per spin for medium-volatility games.
Split Symbols (xSplit Mechanics) (Símbolos Divididos, Símbolos Divididos Split, Разделяющиеся символы (Split))
Slot Mechanics & Engine Features
A proprietary reel modifier, prominently featured in Nolimit City slots, where special symbols slice existing icons in half to double the active ways to win.
Example: In Mental or San Quentin, an xSplit symbol cuts a 5-reel row horizontally, turning 5 single symbols into 10 split symbols to multiply ways.
Standard Deviation (σ) (Sigma, Desvio Padrão, Desviación Estándar, Стандартное отклонение)
RTP & Probability Math
The statistical metric measuring the dispersion or spread of spin returns around the expected mean. High sigma signifies extreme variance and wild bankroll swings.
Example: A low-volatility slot may have σ = 3.5, while an extreme-volatility slot like Tombstone RIP has σ > 14.0, requiring a bankroll 4 times larger.
Sticky Wild (Wild Fixo, Comodín Fijo, Липкий вайлд (Sticky Wild))
Slot Mechanics & Engine Features
A wild symbol that locks into its current grid position for multiple successive spins or for the entire duration of a free-spins bonus round.
Example: In Dead or Alive 2, securing a sticky wild on each of the 5 reels during the bonus round awards 5 extra free spins and massive payout compounding.
Swing Factor (Fator de Oscilação, Factor de Oscilación, Фактор амплитуды колебаний)
Volatility & Variance Dynamics
The ratio of maximum positive bankroll excursion to maximum drawdown, quantifying the extreme volatility dynamics of a particular slot title.
Example: A high swing factor indicates that while balance spikes can be steep, the downward trajectories are equally precipitous.
T
Theoretical vs Observed RTP (RTP Teórico vs Observado, RTP Teórico vs Real, Теоретический и фактический RTP)
RTP & Probability Math
The divergence between the mathematically programmed return in the slot's certified PAR sheet and the actual empirical return logged during a finite session.
Example: A player finishing a 500-spin session with $200 loss on a $1 bet observed an RTP of 60.0%, despite the game's theoretical RTP being 96.5%.
Truncated Pareto Distribution (Pareto Truncado, Pareto Truncada, Усеченное распределение Парето)
Volatility & Variance Dynamics
The power-law distribution model applied to slot bonus payouts, modified with an upper ceiling representing the game's hardcoded max-win cap.
Example: A slot with a 10,000x cap models payouts using a Pareto tail that is mathematically truncated at exactly 10,000x.
V
Variance (σ²) (Variância, Varianza, Дисперсия)
Volatility & Variance Dynamics
The squared standard deviation of spin payouts, serving as the formal mathematical foundation for modeling session bankroll swings and bust probabilities.
Example: A slot with a standard deviation σ = 8 has a variance σ² = 64, requiring a far steeper safety buffer than a game with σ² = 16.
Variance Multiplier (VM) (Fator VM, Factor VM, Множитель дисперсии (VM))
Volatility & Variance Dynamics
A quantitative ratio used in risk modeling to measure the relative increase in variance when purchasing bonus rounds compared to spinning the base game.
Example: A bonus buy feature with a VM of 8.5 concentrates the risk profile of 850 regular base spins into a single instant purchase.
Volatility (Volatilidade, Volatilidad, Волатильность)
Volatility & Variance Dynamics
The degree of risk inherent in a slot's payout schedule, reflecting how frequently and with what magnitude payouts deviate from the theoretical average.
Example: A low-volatility slot pays small amounts frequently, while an extreme-volatility slot can endure 100 dead spins before producing a single large win.
Volatility Index (GLI-19 VI) (GLI-19 VI, Índice de Volatilidade, Índice de Volatilidad, Индекс волатильности GLI)
Volatility & Variance Dynamics
The standardized statistical coefficient defined in GLI-19 gaming standards (VI = z × σ / √N) representing the width of confidence intervals at 90%, 95%, or 99% levels.
Example: Regulatory test labs use VI_95 to verify that a slot's cumulative payouts across 10M spins remain within authorized mathematical boundaries.
W
Wagering Requirement (Rollover) (Rollover, Requisito de Aposta, Вейджер (Wagering Requirement))
Regulations, PRNG & Player Safety
A condition attached to promotional bonus funds dictating the total multiplier of turnover a player must wager before bonus money transforms into withdrawable cash.
Example: A $100 bonus with a 35x wagering requirement requires $3,500 in cumulative slot turnover. At 96% RTP, the expected cost of wagering is $3,500 × 4% = $140, leaving EV negative.
Ways-to-Win (243 Ways) (Formas de Ganhar, Maneras de Ganar, Пути выплат (Ways to Win))
Slot Mechanics & Engine Features
A slot payout mechanic where matching symbols on adjacent reels trigger payouts regardless of their vertical position on the reels.
Example: A 5x3 reel grid with matching symbols on consecutive reels 1, 2, and 3 pays under the 243-ways system (3x3x3x3x3) without requiring fixed paylines.
Wild Symbol (Símbolo Wild, Comodín Wild, Вайлд (Wild))
Slot Mechanics & Engine Features
A special reel symbol engineered to substitute for regular paying symbols to complete or expand winning combinations, often enhanced with multipliers.
Example: Lacking a third king on line 1, landing a Wild on reel 2 bridges the gap between reels 1 and 3 to pay a 3-of-a-kind award.
Win Multiplier (Multiplicador, Multiplicador de Ganancia, Множитель выигрыша)
Slot Mechanics & Engine Features
A numerical coefficient applied to payline, cluster, or total bonus winnings, scaling the base payout by factors ranging from 2x up to 500x or more.
Example: A $10 cluster payout combined with a 50x multiplier bomb in Sweet Bonanza yields a total round payout of $500.
Win Streak (Variance Clustering) (Sequência de Vitórias, Racha Ganadora, Серия выигрышей (кластеризация))
Volatility & Variance Dynamics
A temporary cluster of winning outcomes arising from natural independent random variation, frequently mistaken by players as a slot becoming 'hot'.
Example: Hitting 4 bonus rounds within 50 spins is a variance cluster with zero predictive power over the subsequent 50 spins.
