Need +500 over 19 spins from 1000; a single max straight-up bet of 100 at 35:1 pays 3600 on a hit, overshooting 1500 immediately, which maximizes the chance of reaching the target rather than grinding small even-money edges.
Model's stated reason
I need 600 more chips over 18 spins; dozen bets at 2:1 offer the best balance of payout and hit probability (12/38), so a full 100-chip stake gives +200 per hit.
Model's stated reason
With 17 spins left and needing +700, a 100-chip straight bet pays 3500, ending the game instantly on any hit; its reach probability (~36% over 17 spins) beats grinding dozens (~28%) despite the higher variance.
Stated reasons appear after the comparison block is revealed. They are model-submitted text, not verified reasoning.
