Definitions for all key Aviator and crash-game terminology — written to be neutral, accurate, and accessible.
Multipliernoun
The number displayed during an Aviator round that rises from 1× upward. It represents the factor by which your stake is multiplied if you cash out at that moment. For example, cashing out at 3.50× with a €10 bet returns €35. The multiplier resets to zero ("crashes") at a random point each round.
Cash Outverb / noun
The act of ending your participation in the current round and collecting your winnings — your original bet multiplied by the current multiplier value. Cash-out can be performed manually (by clicking a button) or automatically via the auto cash-out feature.
Auto Cash Outnoun
A feature that automatically cashes out your bet when the multiplier reaches a pre-set target value. Useful for disciplined play without requiring you to watch and react in real time. If the multiplier crashes before reaching your target, your bet is still lost.
RTP (Return to Player)noun / percentage
The theoretical percentage of all bets returned to players as winnings over an extremely large number of rounds. Aviator's RTP is approximately 97%. This is a statistical average across millions of rounds — not a session guarantee. A 97% RTP means the operator retains 3% (the house edge) in the long run.
Volatilitynoun
A measure of how widely individual session results deviate from the average RTP. High volatility (as in Aviator) means individual sessions can produce results far above or below the statistical average — with periods of significant wins and significant losses. Low volatility games tend to produce smaller, more consistent swings.
Provably Fairadjective / noun
A cryptographic verification system allowing players to independently verify that game outcomes were not manipulated by the operator. In Aviator, the crash point is determined by a hash of a server seed (committed before the round) and a client seed. After the round, the server seed is revealed, allowing anyone to verify the calculation. Being provably fair does not change probabilities or give players predictive ability.
House Edgenoun
The mathematical advantage the operator holds over players, expressed as a percentage of each bet. The house edge equals 100% minus the RTP. For Aviator's ~97% RTP, the house edge is ~3%. This means on average, for every 100 units wagered, the operator retains 3. The house edge cannot be overcome by any strategy.
Bankrollnoun
The total amount of money a player has set aside specifically for gambling. Responsible bankroll management means only using funds you can afford to lose entirely, setting strict session limits, and never chasing losses by depositing additional funds beyond your pre-set limit.
Session Risknoun
The total financial exposure during a single gambling session. Session risk is a function of bet size, number of rounds played, and volatility. High-volatility games like Aviator mean that session outcomes can vary dramatically. Responsible play involves setting a session loss limit before starting and stopping when it is reached.
Crash Pointnoun
The multiplier value at which a round ends and all uncashed bets are lost. The crash point is determined randomly before the round starts (using the provably fair algorithm) and is unknown to players in advance. It can occur at any multiplier from 1.00× upward.
Server Seednoun
In provably fair gaming, a cryptographically random string generated by the game server before a round begins. The server seed is hashed (committed) and shared with players before the round. Its actual value is revealed after the round, allowing outcome verification.
Client Seednoun
In provably fair gaming, a value contributed by the player or platform to the round's randomness generation. The combination of server seed and client seed prevents the operator from manipulating outcomes after seeing bets, and prevents players from manipulating the seed in their favor.
Expected Value (EV)noun
The average outcome of a bet if repeated over an infinite number of trials, expressed in monetary or percentage terms. In Aviator (as in all casino games), the expected value of every bet is negative — meaning the long-run mathematical expectation is a loss proportional to the house edge.
Martingalenoun
A betting system where a player doubles their bet after every loss, hoping to recover previous losses with a single win. While it creates the illusion of a safety net, Martingale does not change the underlying negative EV. A losing streak (which is mathematically inevitable over time) can cause catastrophic and rapid bankroll depletion.
Gambler's Fallacynoun
The mistaken belief that previous outcomes influence the probability of future independent events. In Aviator, if the multiplier crashed at 1.2× for the last five rounds, the probability of the next round crashing below 2× is identical to any other round. Past results have no statistical relationship to future ones.
