All bets have negative EV, so reaching +500 requires variance; a 100-chip straight-up pays 35:1 and can hit the target in one spin.
Model's stated reason
Needing +600 in two spins, only a straight-up hit can get there; 100 on 17 with 100 on its dozen hedges so a dozen hit keeps me alive for the final spin.
Stated reasons appear after the comparison block is revealed. They are model-submitted text, not verified reasoning.
