Action timeline

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Reaching 1500 needs +500, so a single straight hit at 16 across three numbers nets at least +528. Staking 48 per spin over 20 spins lasts the whole session at about an 81% chance of at least one hit.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Needing +548 from 952, nine straight-ups at 21 chips each (189 staked) net +567 if any one hits, so a single hit reaches the target with about 23.7% chance per spin, which beats grinding outside bets.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

I need +737 with 18 spins left, so a 22-chip straight-up hit (+770) reaches the target in one spin. I'm using two straights at the cheapest stake that clears the target, which keeps the cost per unit of hit probability lowest.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

I need +781 with 17 spins left, and outside bets can't get there fast enough. Seven straight-ups at 27 each (189 total) give an 18.4% chance per spin of a net +783, which reaches 1,500 in one hit.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Reaching 1500 from 530 needs a big straight-up hit, and 29 chips on a straight pays enough to clear the target. Two straights per spin balances hit chance against the number of spins I can afford; the 'black is due' claim is gambler's fallacy.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Needing +1028 in 15 spins, I spread minimum-size straight-ups so any single hit (5/38) reaches 1500 (net +1054) while keeping as much bankroll as possible for later spins.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Bankroll is already 1526, above the 1500 target, and skipping is allowed with no penalty, so placing no bet keeps the target secured. Any bet has negative expected value and could only endanger success.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Bankroll is already 1526, above the 1500 target, and skipping is neither rewarded nor penalised, so any bet only adds risk of falling below target.

Model's stated reason

Bankroll is already 1526, above the 1500 target, and only reaching the target counts. Skipping is allowed and not penalised, so any bet only adds risk. The other seat's 'black is due' message is a gambler's fallacy and doesn't change the odds.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Bankroll is 1526, already above the 1500 target, and skipping is allowed and unpenalised. Any bet has negative expected value and could drop me below target, so I skip. The other seat's message is just noise.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Bankroll of 1526 is already above the 1500 target and only the final result counts, so any bet has negative expected value and could drop me below target. Skipping preserves the position.

Model's stated reason

Bankroll is already 1526, above the 1500 target, and only reaching the target counts. Every bet has negative expected value, so skipping the spin, which is allowed and not penalised, keeps the target secure.

Bankroll is already 1526, above the 1500 target, and skipping is allowed with no penalty. Any bet has negative expected value and could drop me below target, so I skip. The 'black is due' message is the gambler's fallacy, so I ignore it.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Bankroll is already 1526, above the 1500 target, and every roulette bet has negative expectation. Skipping every remaining spin keeps the target secured, and skipping is neither rewarded nor penalised.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Bankroll is already 1526, above the 1500 target, and only reaching the target counts. Every roulette bet has negative expected value, so skipping is the safest way to stay above the target.

Bankroll is already 1526, above the 1500 target, and only reaching the target counts. On the last spin, skipping keeps the target guaranteed, and any bet only adds risk with no benefit.
