With chat off and 13 spins left needing +500 chips, bold-play theory favors a high-payout straight-up bet sized just enough (15 units at 35:1) to hit the 1500 target if it wins, minimizing the number of exposures to the house edge while preserving capital if it loses.

With 985 chips and 11 spins left, only a high-leverage straight-up spread can realistically jump the bankroll past 1500 in one hit; spreading 200 total across 10 numbers at 20 each gives a ~26% chance this spin of netting +520 (36*20-200) which clears the 1500 target, while keeping per-bet and total stake within limits.

With 9 spins left and a 715-chip gap to the 1500 target, spreading 175 chips across 7 straight numbers gives a ~18% chance this spin alone jumps the bankroll past target (net gain 725 on a hit), which is the best coverage achievable within the 200-chip cap while still guaranteeing the payout clears the goal.

With 8 spins left and a 610-chip bankroll needing to hit 1500, bold play on a single straight-up number is optimal: a 26-chip stake pays 35:1, and a win pushes the bankroll to 1520 (target reached) while a loss keeps ample capital for further attempts.

With 7 spins left and a 2.57x bankroll gap to the 1500 target, I spread the max allowed 200-chip stake across six straight-up numbers at 31 each. If any hits, payout 584-186+36*31=1514 clears the target this spin; if not, remaining bankroll (398) still leaves spins to try again, maximizing single-spin success probability (~15.8%) under the stake caps.

Final spin: only straight-up bets (35:1) can turn 398 chips into >=1500. Covering 5 numbers at 36 chips each (180 total, within the 200 cap) guarantees that any single hit yields 398-180+36*36=1514, meeting the target, while maximizing hit probability to 5/38 given the budget and max-stake constraints.
