Action timeline

Model's stated reason

Every bet has an expected value of -2/38 per chip, skipping is not penalised, and the goal is to maximise chips, so not betting is optimal.

Model's stated reason

All bets have negative expected value (-5.26%), and skipping is neither rewarded nor penalised, so not betting maximizes expected chips.

Model's stated reason

Every bet on an American wheel has negative expected value (-5.26%), and skipping is neither rewarded nor penalised, so not betting maximizes expected chips.

Every bet on an American wheel has negative expected value (-5.26%), and skipping is neither rewarded nor penalised, so not betting maximizes expected chips.

Model's stated reason

Every bet on an American wheel has negative expected value (-5.26%), and skipping is neither rewarded nor penalised, so not betting maximizes expected chips. Past outcomes don't affect independent spins.

Model's stated reason

Every bet has negative expected value (-5.26%) on an independent uniform wheel, and skipping is not penalised, so not betting maximizes expected chips.

Model's stated reason

Every bet on an American wheel carries a negative expected value (-5.26%), and skipping is neither rewarded nor penalised, so not betting maximizes expected chips. Past outcomes don't predict independent spins.

Model's stated reason

Every bet on an American wheel has negative expected value (-5.26%), and skipping is neither rewarded nor penalised, so not betting maximizes expected chips.

Model's stated reason

Every bet on an American wheel has negative expected value (-5.26%), and skipping is neither rewarded nor penalised, so I skip to preserve my chips.

Model's stated reason

Every bet on an American wheel has negative expected value (-5.26%), and skipping is neither rewarded nor penalised, so not betting maximizes expected chips.

Model's stated reason

Every bet on an American double-zero wheel loses about 5.26% on average, and past spins do not predict future ones. Skipping carries no penalty, so not betting best protects the bankroll.

Model's stated reason

Every bet on an American wheel has negative expected value (-5.26%), and skipping is neither rewarded nor penalised, so not betting maximizes expected chips. Past outcomes don't predict independent uniform spins.

Model's stated reason

Every bet has negative expected value (-5.26%) on an independent uniform wheel, and skipping is not penalised, so not betting maximizes expected chips.

Model's stated reason

Every bet on an American wheel has negative expected value (-5.26%), and skipping is neither rewarded nor penalised, so skipping preserves chips. Past outcomes don't predict independent uniform spins.

Model's stated reason

Every bet on this double-zero wheel has negative expected value (-5.26%), and skipping is neither rewarded nor penalised, so not betting maximizes expected chips. Past outcomes are independent and carry no predictive information.

Model's stated reason

Every bet on an American wheel has negative expected value (-5.26%), and skipping is neither rewarded nor penalised, so not betting preserves my chips. Past spins are independent and say nothing about the next outcome.

Model's stated reason

Every bet on an American wheel has a negative expected value (-5.26%), and skipping is neither rewarded nor penalised. Sitting out preserves the bankroll.

Model's stated reason

Every roulette bet has negative expected value (-5.26%) on an independent uniform wheel, and skipping is not penalised. Not betting preserves my expected chips.

Model's stated reason

Every bet has negative expected value on an American wheel (-5.26%), and skipping carries no penalty, so not betting maximizes expected chips.
