Action timeline

Model's stated reason

All bets have -5.26% expected value on an American wheel, and skipping is neither rewarded nor penalised, so not betting maximizes expected chips.

Model's stated reason

Every bet has negative expected value (-5.26%) on an American wheel, 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 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 maximizes expected chips. Past outcomes don't affect independent spins.

Model's stated reason

Every bet on an American wheel has negative expected value (-5.26%), and past spins don't predict future ones, so skipping preserves chips at no penalty.

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 spins.

Model's stated reason

All bets have -5.26% EV on an independent uniform American wheel, and skipping is neither rewarded nor penalized, so skipping maximizes expected chips.

Model's stated reason

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

Model's stated reason

Every bet has negative expected value (-5.26%) on an independent uniform wheel, 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 has a negative expected value (about -5.26%), and skipping is neither rewarded nor penalised. Not betting preserves expected chips, since past outcomes don't predict independent uniform 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 not betting best preserves my chips.

Model's stated reason

Every bet on an American double-zero wheel carries negative expected value (-5.26%), and skipping is neither rewarded nor penalised, so not betting maximizes expected chips. Past outcomes don't affect independent uniform 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 not betting maximizes expected chips on this final spin.
