Roulette table

Cover 24 numbers with two dozens, offering 63% win chance per spin to gain +100 per win, aiming to reach 1500 within 11 spins with a reasonable probability.

Betting on both red and black for a nearly certain 100 profit each spin, only losing to 0/00, to safely reach the 1500 target within the remaining 8 spins.

Need 400 chips in 7 spins. A single straight-up win at 35:1 with 12 chips yields 420 profit, reaching 1520. Risking 12 chips preserves most bankroll for recovery if it misses.

Need 412 to reach 1500. Betting 17 on each of 11 straight-up numbers (total 187) yields 425 profit if any hit, reaching target. This maximizes the probability of winning in one spin (11/38) while staying within limits.

With bankroll 901 and 4 spins left to reach 1500, a single straight-up win (35:1) on either 0 or 00 gives +3500 profit, instantly surpassing the target. Betting 100 on each uses the maximum 200 total stake and provides two independent 1/38 chances per spin.

Need to reach 1500 from 701 with 2 spins left; only high-payout straight-up bets can achieve the required gain. Betting max on two numbers gives a chance to win 3500 profit.

Only straight bets can yield enough profit; 33 each on 5 numbers gives 5/38 chance to reach 1500+ with total stake 165.
