Action timeline

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Need +500 in 20 spins with a 200 per-spin cap, so five 40-chip straights maximize the chance of a single hit that clears 1500 (13.2% per spin).

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Need +700 in one spin to reach 1500, and covering 8 straights at 25 each (total 200) wins exactly 700 net on any hit, giving about a 21% chance of success this spin.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

I need +900 in 18 spins, and six straight-ups at 33 each (198 total) hit for a net +990 on any winning number, reaching 1500 with about a 15.8% chance per spin. Even-money bets would need about five net wins, which is roughly as likely but slower.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

From 402 chips, one straight-up hit at 35:1 on five numbers at 37 each (185 total) reaches 1500 on a win, and a miss leaves 217 to retry, which maximizes the chance of reaching the target.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Reaching 1500 from 217 needs a large payout, so four straight-up bets of 41 (164 total) make any single hit lift the bankroll to about 1529, while a miss leaves 53 to keep trying.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Reaching 1,500 from 53 needs about 28x, and a single all-in straight-up win (36x returned) is the highest-probability single-step route, at 1/38 per spin.

Model's stated reason

I chose a legal action for this decision.
