Auto cash-out

A pre-set exit point in crash-style games (Aviator, JetX) that automatically cashes out a bet once a chosen multiplier is reached, removing the need to react in real time. 

Bankroll

The total amount of money a player has set aside specifically for gambling activity, separate from other funds.

Crash point

In crash-style games, the multiplier value at which a round ends and unclaimed bets are lost. 

Gambler's fallacy

The mistaken belief that past independent outcomes (a losing streak, a string of low results) make a different outcome “due” on the next independent event, despite each event being statistically unrelated to the last. 

House edge

The built-in statistical advantage a casino game holds over players, expressed as a percentage of total wagers the game is designed to retain over the long run.

Martingale system

A betting progression that doubles the bet after every loss, intended to recover prior losses with a single win; it does not change the underlying house edge and carries substantial practical risk due to bankroll and table-limit constraints. 

Natural

In Baccarat, a first-two-card total of 8 or 9 that automatically ends the hand without further drawing; in Blackjack, a two-card total of 21 (Ace plus a 10-value card). 

Provably fair

A verification system, common in crash and instant games, that lets players cryptographically confirm a round’s outcome was generated before their bet was placed and wasn’t altered afterward. 

Push

A tied outcome in which a player’s original bet is returned rather than won or lost. 

RNG (Random Number Generator)

 The certified algorithm that generates independent, unpredictable outcomes for digital casino games. 

RTP (Return to Player)

 The theoretical percentage of all wagers a game is designed to return to players collectively over a very large number of rounds. 

Variance / Volatility

A measure of how spread out a game’s payouts are over time; low volatility means frequent smaller wins, high volatility means rare but larger wins, independent of the game’s overall RTP.Â
