Action timeline

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

A 100-chip even-money bet on red gives a near-even chance to build toward the 500-chip gain without exposing the whole bankroll on one spin.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

I need +400 in 19 spins, and near-even-money bets at the 100 cap give the best odds of reaching the target, so I'm betting 100 on red.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

I need a net gain of 500 from 1000, so a single hit on ten straight-up numbers at 20 each returns about 520 and reaches the target, with about a 26% chance per spin and the full 200 stake cap used.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

I need +700 with 17 spins left, and only reaching the target counts, so a high-variance single straight with a 20-chip stake hits the exact target if it lands.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Needing +720 with 16 spins left, seven 25-chip straights cover 7 of 38 pockets; any hit nets about +725 and reaches 1500, while the 175 total stake stays within limits.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

I need +895 in 15 spins, so six straight-ups totaling 200 chips reach 1500 on any single hit, about a 15.8% chance this spin.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Reaching 1,500 from 405 in 14 spins needs high variance, so I spread the 200 per-spin cap across five straight-ups for about a 13% chance to win roughly 1,240 and clear the target in one spin.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Bankroll 205 needs about 7.3x in 13 spins, so I'm covering three straights at 40 each: a hit returns about 1525, and a miss still leaves 85 for another attempt.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

With 85 chips and 12 spins left, reaching 1500 requires about a 17.6x gain, and only a single straight-up hit (35:1) does that in one spin, so a full-bankroll straight is the highest-probability route despite the 1/38 odds.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

The observation shows bankroll 0, max_total_stake 0, and no legal_bet_ids, so no bet is legal this spin and I am passing.
