Action timeline

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Bold-play: covering 10 numbers at 20 each nets exactly +520 on a hit, reaching the 1500 target in one spin with ~26% probability, while leaving bankroll for similar max-coverage attempts on following spins (~62% cumulative success).

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Need +700 with max 200/spin; even-money grinding is unlikely to net 4 wins against the edge, so I bet two straight-ups sized so a single hit (756 return on 42 staked) clears 1500, sustainable for ~13 spins (~50% to hit at least once).

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Down to 758 with 18 spins left and need +742; 2:1 bets give a better chance of reaching the target than even-money grinding or longshot straight-ups, so I take max exposure on dozen_2 and column_2 (splitting across two ids to stay within the 100 per-bet cap).

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Need +642 in 17 spins; a single 100-chip 2:1 dozen bet maximizes the probability (~36% by DP) of reaching 1500 versus even-money (~12%) or straight-up (~19%) approaches, while matching the single-bet policy the scoring references.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Target is far above bankroll, so bold play on straight-ups maximizes reach probability; 22 per number is the minimum stake where a single hit crosses 1500 (758+34*22=1506), and two numbers per spin buys extra cheap chances while leaving enough bankroll to keep firing every remaining spin.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Needing +786 in 15 spins with a 200/spin cap, even-money bets can't realistically get there; straight-up tickets sized so one hit (24 x 36 = 864 minus 72 stake) lands exactly over 1500 maximize reach probability, and three numbers per spin keeps total tickets high across the remaining bankroll.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

At 642 chips with 14 spins, even-money grinding to 1500 is near-hopeless, so the best path is straight-up bets sized so a single hit exactly reaches the target (642-78+36*26=1500); three numbers per spin sustains ~7 spins of coverage, giving roughly a 40% success chance, the best among the sizing schedules I compared.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Need +936 in 13 spins with 564 bankroll; a single straight-up hit at 27 chips (+945) reaches the target in one spin, so I cover 7 numbers at the minimum stake that suffices (18.4% this spin) while keeping enough bankroll for two more similar attempts.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

At 375 with 12 spins left, even-money bets can't realistically reach 1500; a 33-chip straight-up win (+1155) clears the target in one hit, and sizing at the minimum needed stake preserves the most spins/exposures (~10), giving roughly a 23% success chance.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Need +1158 in 11 spins; only straight-up hits can get there. Betting the minimum stake that reaches 1500 on a hit (34*35=1190) maximizes the number of attempts (9) before bust, giving ~21% success vs ~10% with max stakes.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Only straight-up hits can reach 1500 from 308; stake 36 is the minimum per number so that a single hit clears the target, and spreading minimal stakes across spins maximizes the number of 1/38 attempts (~7 total) within the remaining bankroll.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Bankroll of 1532 already exceeds the 1500 target, and only finishing above target counts, so skipping preserves the win with zero risk.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Bankroll is already 1532, above the 1500 target; since only reaching the target counts and skipping is unpenalised, the optimal policy is to place no bets and lock in the success.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Bankroll 1532 already exceeds the 1500 target with 7 spins left; skipping is allowed and locks in success since any bet only risks falling below target.
