Roulette table

Covering three straight numbers with the minimum stake that reaches 1500 on a hit gives a high per-spin success chance while preserving bankroll for repeated attempts if it misses.

Need 548 to reach 1500; a 16-chip straight-up win pays 560 and reaches the target in one spin while minimizing losses on misses to preserve many attempts.

Need 564 to reach 1500; a 17-chip straight-up win pays 595 and reaches the target in one hit, while the small stake preserves bankroll for repeated attempts over 18 spins.

Any one of three straight numbers nets +594 and reaches 1500, while risking only 54 to preserve bankroll for many further attempts if it misses.

Gap to target is 635, so a 19-chip straight-up bet nets at least 665 on a win and reaches 1500 immediately, while risking minimal bankroll to preserve chances over the remaining 16 spins.

With 654 needed and a 100 cap, only a straight-up win can reach 1500 in one spin; staking ceil(654/35)=19 makes any hit succeed while preserving bankroll for up to 15 attempts.

Bankroll 827 is 673 below target with 14 spins left; a straight-up bet sized ceil(673/35)=20 reaches 1500 on any hit, giving about a 31% chance of at least one hit, far better than capped even-money or dozen bets.
