Need +500 in 20 spins; a single straight-up hit at 16 chips (net +528 after the other two lose) reaches the 1500 target immediately, and spreading over 3 numbers at ~48 chips/spin keeps the bankroll alive for ~12 spins, giving roughly a 60%+ cumulative chance to hit, better than even-money grinding.

Need +548 in 19 spins; even-money grinding at the 200 cap succeeds only ~20% of the time, whereas small straight-up bets sized so a single hit clears the target give ~60% over the horizon. Two numbers at 17 each nets +561 on a hit (952 -> 1530).

Need +582 with 18 spins left; three straight-ups at 18 each net +594 on any hit, reaching the target in one spin while keeping per-spin cost low enough to repeat many times.

Need +636 in 17 spins; a 19-chip straight-up hit pays 665 and clears the target in one shot, and spreading over two numbers per spin uses the bankroll across ~15 spins for roughly a 55% chance of at least one hit, far better than grinding even-money bets.

Need +674 in 16 spins; even-money grinding is unlikely, so I bet the minimum straight-up stake (20 chips, 35:1 pays 700) on two numbers each spin, sized so any single hit clears 1500 while the bankroll sustains coverage across most remaining spins.

Need +714 with 15 spins left; two straight-up bets of 21 each land exactly on 1500 if either hits (2/38 per spin) while keeping the burn rate low enough to retain ~13 attempts, which maximizes reach-target probability (~50%) versus even-money grinding (~15%).

Need +756 in 14 spins with 744 chips; only a straight-up hit can reach 1500 in one go, and spreading 24 on four numbers (4/38 per spin, win lands exactly 1512) sustains ~6 attempts for roughly 47% success, better than dozen or even-money bold play.
