The Aviator Martingale strategy suggests doubling your bet after each unsuccessful round. For example, if you start with a bet of 10 and the plane crashes before cashing out, your next bet should be 20. If that round also fails, you increase your bet to 40.
For the best results in this game, use the auto-bet and auto-cashout functions at multiplication x1.2 for the first bet and the moderate risk strategy for the second bet. In a two-part game, stop after multiplying the first bet by x40 and the second stake by x100.
