Roulette table

Need +500 in 20 spins; two straight-ups at 15 each pay net +510 on a hit (2/38 per spin), and the geometric stake growth needed after losses stays affordable for ~19 spins, giving roughly 64% chance to reach the target versus ~41% for a single number.

Need +530 to reach 1500; a 17-chip straight-up hit nets 595-34=561, clearing the target in one spin while keeping per-spin cost low enough to retry ~12 times, which beats grinding even-money bets.

Need +581 with only success counting, so maximize the chance of a single jackpot-sized hit: 9 straight-up bets at 22 each (198 total) so any hit lands bankroll at 1513 ≥ 1500, giving ~24% this spin and roughly 58% over the planned ladder of spread straight-up bets.

Need +779 with 17 spins left; even-money grinding is unlikely to net +4 wins, so bold play on straight-ups is best. Two numbers at 23 each: any hit yields 721-46+828=1503 >= target, and this stake level stretches the bankroll across ~15 spins for roughly 55% cumulative hit chance.

Need +825 in 16 spins; a single straight-up stake of 42 reaches the 1500 target on any hit even if it comes on the last spin (675-42*15+42*35=1515), giving ~35% success, far better than even-money or multi-number spreads.

Need +867 with 15 spins left; even-money grinding needs ~10 of 15 wins (~8%), while a 25-chip straight-up hit (35:1) clears the target in one go. Spreading 25 on four numbers maximizes number-spins (~20) before the bankroll runs out, giving roughly a 40% chance of at least one hit.

Bankroll 1433 needs only +67 to hit the 1500 target; a 67-chip even-money bet reaches it exactly on a win (~47.4%), the highest single-spin probability available, while leaving 13 spins to recover if it loses.

Need exactly +134 to hit 1500; a 67-chip dozen bet pays 2:1 and reaches the target in one spin with ~31.6% chance while risking only 67, keeping 1299 and 11 spins to recover if it misses.

Need +201 with 11 spins left and a 200 cap; dozen_3 plus high overlap fully so any 25-36 pays +300 and clears the 1500 target in one spin (12/38), while 19-24 is a push and only 0/00/1-18 loses the 200.
