Auto-Cashout — A preset multiplier target that triggers automatic cash-out when reached. Executes server-side, eliminating network latency. The most reliable way to play crash games consistently.

Bust / Crash — When the round ends and the multiplier stops climbing. Any player who has not cashed out loses their bet. Crash points are predetermined by the provably fair algorithm before the round begins.

Client Seed — A value generated from player actions (bets placed in a round) that combines with the server seed to determine the crash point. Prevents the casino from predicting outcomes in isolation.

Dual Bet — Feature allowing two simultaneous bets per round (available in Aviator). Enables hedging strategies where one bet targets low consistent returns and the other targets high multipliers.

Hash Chain — A sequence of cryptographic hashes where each value is derived from the next. Used in provably fair systems to pre-commit game results. Modifying any value breaks the chain, making manipulation detectable.

House Edge — The mathematical advantage the casino holds. In a 97% RTP game, the house edge is 3%. This means for every $100 wagered, the casino expects to keep $3 on average.

Multiplier — The number that climbs during a crash game round. Starting at 1x and increasing until the crash. Your payout = bet × multiplier at cash-out.

Nonce — A counter value that increments with each round. Combined with seeds to produce unique results per round while maintaining the hash chain structure.

Provably Fair — A cryptographic verification system allowing players to independently confirm that each game round was predetermined and unaltered. Uses SHA-256 hashing in most implementations.

RTP (Return to Player) — The percentage of total wagered money returned to players over time. A 97% RTP means $97 returned per $100 wagered on average. Individual sessions deviate significantly from this average.

Server Seed — The casino's secret value used to generate crash points. Revealed after each round so players can verify the result. Pre-committed via hash chain before play begins.

SHA-256 — Secure Hash Algorithm producing a 256-bit hash. Used in Bitcoin and in crash game provably fair systems. Computationally infeasible to reverse or forge, making it ideal for game verification.

Triple Bet — Feature allowing three simultaneous bets (available in JetX). Enables more complex hedging configurations than dual bet systems.

Variance — The statistical measure of how far individual results spread from the expected average. High variance means bigger swings between sessions. Crash games are inherently high variance due to their skewed payout distribution.

Volatility — Often used interchangeably with variance in gambling contexts. Describes how "swingy" a game feels. Spaceman has slightly higher volatility than Aviator despite similar RTP.

Start with five core terms: RTP, auto-cashout, multiplier, provably fair, and house edge. These cover 90% of what you need to understand as a new player. The remaining terms become relevant as you explore advanced strategies and verification processes.

Play 50 free/demo rounds of Aviator before wagering real money. During those rounds, practice using auto-cashout at different targets. Observe how often the game crashes below 1.5x, 2x, and 3x. This hands-on experience teaches terminology faster than any glossary because you connect abstract concepts to visible gameplay mechanics.

After your demo session, verify one round using the provably fair tool. This single exercise teaches you what server seeds, client seeds, and hash chains actually do — not just what they are called. Most players never bother to verify a round. The 2 minutes it takes will give you more confidence in the system than reading a hundred forum posts about crash game fairness.
