Dual-Bet Strategy Comparison
Aviator lets you place two independent bets per round. Here's how splitting your budget compares:
| Strategy | Cashout | Win Rate | Bet Size | Risk |
|---|
A common dual-bet approach: use Bet 1 for a low cashout (1.20x–1.50x) to recover losses, and Bet 2 for a higher target. Both bets still carry a 3% house edge each.
Probability of Reaching Multiplier
Based on Aviator's 97% RTP: P(reaching x) = 0.97 / x
Kelly Criterion Bet Size
The Kelly Criterion calculates the mathematically optimal bet size to maximize long-term bankroll growth. Because Aviator has a negative expected value (3% house edge), full Kelly recommends $0 — you should not bet at all from a pure math perspective.
Kelly Criterion only recommends betting when you have a positive edge. In Aviator, the house always has a 3% edge. The bet sizes above are for entertainment budgeting — not a path to profit. Never bet money you can't afford to lose.
