Roulette table

Need +500 in 17 spins, so high-variance plays are appropriate: a 100 straight-up hit jumps to 3500 instantly, while the 100 red hedge gives partial recovery (e.g. 25 wins red too, netting +4400... actually +3400+100).

Splitting 200 across two dozens gives a ~63% chance of gaining 200 per spin, the best growth-vs-risk profile to reach 1500 within 15 spins.

Bankroll 1100 needs 400 more in 12 spins; even-money bets at the 200 cap give steady upside with controlled risk.

A 100-chip dozen win pays 200, exactly reaching the 1500 target, so a single dozen bet each spin is the most direct path with 10 spins left.

Need +300 in 9 spins; a 100-chip dozen bet wins 200 on a hit, keeping risk limited while giving steady progress toward 1500.

I need only 100 chips to reach 1500 with 7 spins left; a 100 even-money bet wins 100 with ~47% probability, and losing still leaves 1300 with time to recover.

Bankroll already equals the 1500 target; betting only adds downside risk, so I skip.

Bankroll is already at the 1,500-chip target; any bet risks falling below it while success only counts once reached. Betting nothing locks in success.

Bankroll is already at the 1,500-chip target; any bet only risks dropping below it. Optimal play is to not bet.

Bankroll is already at the 1500 target with 3 spins remaining; any bet only risks falling below target since success-only scoring counts the final bankroll.

Bankroll is already at the 1500 target; any bet only risks falling below it with no upside.

Bankroll is already at the 1500 target and only one spin remains; any bet risks falling below target while success-only scoring gives no reward for exceeding it, so the optimal action is to skip betting.
