Roulette table

Need +500 in 20 spins; bold play with the maximum even-money bet maximizes target-reach probability while preserving bankroll for later spins.

Need 400 more in 19 spins; a straight-up bet needs only 12 to gain 420 and reach target, minimizing loss per attempt while giving repeated 1/38 chances to hit.

Need 412 to reach 1500; a 12-chip straight-up win pays 420 and reaches the target immediately, while risking little so the attempt can be repeated over the 18 remaining spins.

Bold play maximizes reach probability in a subfair game: bet the maximum 100 on an even-money chance, needing 424 more with 17 spins left.

Need 524 in 16 spins; a 27 straight bet pays 945 profit, so any single hit in the remaining spins reaches 1500 while preserving bankroll for all 16 trials, maximizing hit probability.

With 551 needed and 15 spins left, a straight-up win must gain at least the gap; 16 is the smallest stake whose 35:1 profit (560) reaches 1500, preserving bankroll for the maximum number of attempts.

Need 567 more; a 17-chip straight win pays 595 and reaches 1500 while risking little, preserving bankroll for repeated 1-in-38 shots over the remaining 14 spins.

Need 584 more with 13 spins left; a 17-chip straight-up win pays 595 and reaches the target while minimizing losses to preserve repeated attempts.

Need 601 to reach 1500; an 18-chip straight-up win pays 630 and reaches the target in one spin while minimizing losses and preserving bankroll for the remaining 12 attempts.

Need 619 to reach 1500; an 18-chip straight bet profits 630 on a hit, giving an immediate success chance each spin while preserving bankroll for the remaining 11 attempts.

Covering five straight numbers at 21 each gives a 5/38 chance to gain 651 and reach 1514 immediately, while limiting the loss on a miss to 105 and preserving repeated attempts in the remaining spins.

Need 742 more; a straight-up win pays 35:1, so 22 is the minimum stake that reaches 1500 in one hit (758+770=1528), preserving bankroll for repeated attempts over the remaining 9 spins.

Need 764 in 8 spins; covering 7 numbers at 27 each gives an 18.4% chance to gain 783 and reach 1500 immediately, while preserving 547 after a miss for further attempts.

With 547 chips and 7 spins left, a 28-chip straight-up bet gains 980 on a hit, just reaching 1500 while preserving bankroll for the maximum number of subsequent attempts if it misses.

Need 981 to reach 1500. Covering 6 straight numbers at 33 each costs 198; any hit returns 1188 for a bankroll of 1509, maximizing immediate reach probability while leaving 321 after a loss for further attempts.

Bankroll 1509 already exceeds the 1500 target with 5 spins remaining, so betting only risks falling below target; skipping preserves success.

Bankroll 1509 already exceeds the 1500 target with 4 spins left, so skipping avoids any risk of falling below target.

Bankroll 1509 already exceeds the 1500 target with 3 spins remaining, so betting nothing preserves success.

Bankroll 1509 already exceeds the 1500 target with 2 spins remaining, so betting only risks falling below; skip to lock in success.

Bankroll 1509 already exceeds the 1500 target with one spin left, so placing no bet preserves the successful outcome.
