Official solution using RNG prediction and seed brute forcing. Very detailed, including a full explanation of the decompiled code.

Java roulette simulator. Decompiled with JADX and recovered a custom 16-bit PRNG used for win/loss. Brute-forced the PRNG seed from observed outcomes to predict future rounds, then used a betting strategy to grow balance until a 32-bit signed integer overflow flips it negative, satisfying the “win” condition.
