A 15-chip straight pays enough to clear 1500 in one hit, and 13 numbers is the most coverage the 200 stake cap allows at that size, maximizing the chance to reach the target this spin.
Model's stated reason
I need 695 more and only a straight-up win can clear the target in one spin; a stake of 20 pays exactly enough while leaving bankroll for the remaining spins if it misses.
Stated reasons appear after the comparison block is revealed. They are model-submitted text, not verified reasoning.
