Roulette table

A straight-up win needs only ceil(500/35)=15 to reach 1500, preserving bankroll for up to 20 independent attempts while any hit reaches the target.

Need 515 to reach 1500; a 15-chip straight-up bet pays 525 on a win, reaching the target in one spin while risking little, preserving bankroll for repeated attempts over 19 spins.

Only a straight-up win can reach 1500 in one spin; 16 is the minimum stake whose 35:1 profit (560) covers the 530 shortfall, preserving bankroll for up to 18 attempts.

Betting 17 on each of two numbers reaches the target on a hit (578 net profit) while risking only 34, preserving bankroll for repeated attempts over the remaining 17 spins.

Only a straight-up bet can reach 1500 in one spin; staking ceil(580/35)=17 makes a hit pay enough to reach the target while minimizing the cost of a miss over the remaining spins.

Need 597 more with 15 spins left; a straight-up win pays 35:1, so 18 is the smallest stake whose win reaches 1500. Repeating this minimum one-shot sizing preserves bankroll to keep a target-reaching chance on every remaining spin.

Need 615 to reach 1500. Three straight bets at 19 each net 627 on any hit, giving a 3/38 chance to reach the target immediately while costing only 57 on a miss, preserving many repeat attempts.

Covering eight straight numbers at 24 each gives an 8/38 chance to gain exactly 672 and reach 1500 this spin, the maximum one-spin coverage possible within the 200 total stake cap.

Bankroll 636 needs 864 to reach 1500; a 25-chip straight-up win pays 875, enough in one hit, while the small stake preserves bankroll for repeated attempts over the remaining 12 spins.

Far from target with 11 spins left, covering three straight numbers at 27 each makes any hit gain 891 and reach 1502, while costing only 81 if it misses and preserving repeat attempts.

Bankroll 530 needs 970 to reach 1500; a 28-chip straight-up win pays 980 and reaches the target immediately, while the minimal stake preserves bankroll for repeated attempts over the remaining 10 spins.

Needing 998 in 9 spins, a 29-chip straight-up win pays 1015 and reaches 1500 immediately, while preserving bankroll for repeated attempts. This maximizes the one-hit success chance versus lower-payout bets that cannot close the gap quickly enough.

With 473 chips, 8 spins left, and 1027 needed, even-money and dozen bets cannot efficiently reach the target. Covering five straight numbers at 34 each makes any hit profit 1054 and reach 1527, maximizing hit probability while preserving a second aggressive attempt if this misses.

Bankroll 303 needs 1197 to reach 1500; a 35-chip straight-up win pays 1225 profit, enough in one hit while preserving bankroll for up to seven such attempts.

With 268 chips and 6 spins, covering three straight numbers for 38 each reaches 1522 on any hit while preserving 154 chips for another attempt if it misses.

Need 1346 more to reach 1500; a straight-up bet pays 35:1, so 39 is the minimum stake that reaches the target on a win while preserving bankroll for the remaining spins if it misses.

Bankroll 115 needs 1385 in 4 spins; a 40-chip straight-up win pays 1400 and reaches the target immediately, while preserving 75 chips for further sufficient straight-up attempts if it loses.

Betting 41 on a straight number reaches 1500 if it hits, while preserving 34 chips for a two-spin recovery attempt if it misses.

Last spin with 34 chips and target 1500 is unreachable, but a straight-up bet gives the maximum possible payout (36x return) and closest approach to the target.
