Model's stated reason
I chose a legal action for this decision.
Model's stated reason
Need +500 with 20 spins and ~1000 chips; cheapest path is straight-up bets sized so any hit clears 1500 (1000-30+540=1510). Two numbers at the minimal stake maximizes total number-spin coverage over the session (~40 covered number-spins, ~65% success) while preserving bankroll for later spins.
Model's stated reason
I chose a legal action for this decision.
Model's stated reason
Need +530 in 19 spins; a single straight-up hit at 18 chips across 5 numbers (18*36-90=558) clears the target in one spin, and spreading across ~5 numbers per spin at affordable cost maximizes cumulative hit probability (~65-70%) versus even-money grinding.
Model's stated reason
I chose a legal action for this decision.
Model's stated reason
Reaching 1500 from 880 needs a straight-up hit; 19 on each of two numbers gives 1526 on a hit while keeping stakes small enough to sustain ~15 spins, maximizing cumulative hit probability (~55%) versus even-money grinding.
Model's stated reason
I chose a legal action for this decision.
Model's stated reason
Need +658 in 17 spins with a 200 cap, so even-money grinding is unlikely; two straight-up bets at 20 each pay 680 net on a hit (reaches 1500) at 2/38 per spin while burning only 40 chips, sustainable for ~15 spins for roughly 55% cumulative hit chance.
Model's stated reason
I chose a legal action for this decision.
Model's stated reason
Bankroll (1522) already exceeds the 1500 target and only finishing at or above it counts, so any further wager only adds risk of dropping below; skipping is the optimal, non-penalised action.

Bankroll of 1522 already exceeds the 1500 target and only finishing above it matters, so skipping every remaining spin locks in success with zero risk.
