Roulette table

Since only reaching 1500 matters (not the amount by which we exceed it), the optimal single-bet policy is to cover as many numbers as possible with the minimum stake (15) needed on each straight-up bet so that any hit instantly pushes bankroll past the 1500 target, maximizing per-spin hit probability (13/38) within the 200-chip cap.

Need 695 more chips; a 20-chip straight-up bet pays 35:1, which would push bankroll to 1505 (target) if it hits, while keeping the loss small (20 chips) to preserve capital for future spins.

Using bold-play: a single straight-up bet at minimum stake (21) yields a payout that reaches the 1500 target if it hits, minimizing the number of high-variance wagers needed under the fixed house edge, which maximizes the probability of hitting the target within the remaining spins.

With only 2 spins left and needing to roughly double my bankroll, only 35:1 straight-up bets can realistically close the gap to 1500; covering two numbers at max stake doubles the hit probability while keeping the same huge payout if either lands, and a hit here would already clear the target so I can lock in on the final spin.
