Roulette table

Optimal bold play with max bet 100: bet 100 on red to maximize probability of reaching 1500.

Betting 19 on four straight numbers gives a chance to reach the 1500 target in one hit while conserving bankroll for multiple spins.

Betting 40 on three straight numbers maximizes the chance of a single hit reaching the 1500 target while preserving enough bankroll for a second attempt if the first six spins miss.

Betting on 5 straight numbers with 26 each gives a 5/38 chance to reach 1500 immediately, while preserving enough bankroll (574) to continue if missed; this balances coverage and future attempts.

I need 926 chips to reach the 1500 target. Six straight bets at 31 each cost 186 and any hit nets 930, reaching the target while maximizing the number of covered pockets within the per-spin stake limits.

Need high variance to reach 1500 from 388 in 10 spins. Betting 33 on six straights gives ~15.8% chance to hit; if hit, bankroll becomes 1378, leaving only 122 needed with 9 spins left, where one even-bet win is ~99.7% likely. This maximizes overall success probability.

On the final spin, only straight-up bets can reach 1500 from 190. Covering four numbers with stakes totaling 190 gives the maximum win probability while ensuring any hit yields at least 1500.
