Need +500 with at most 200 staked, so ten straight-ups of 20 each: any hit nets +520 and clears the target, and this is the widest one-spin reach available.
Model's stated reason
With two spins left and 700 chips short, eight straight bets of 25 cover the most pockets that still reach 1500 on a hit. A miss leaves 600, enough for another six-number attempt next spin.
Model's stated reason
Bankroll is already exactly at the 1500 target on the final spin, so any wager can only risk falling below it. Skipping preserves the target with certainty.
Stated reasons appear after the comparison block is revealed. They are model-submitted text, not verified reasoning.
