Action timeline

Model's stated reason

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

Model's stated reason

Every bet on a uniform 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.

Model's stated reason

Every bet has negative expected value (-5.26%) on an independent uniform American 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 (-5.26%), and past spins don't predict future ones, so skipping preserves expected 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

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 wheel has negative expected value (-5.26%), and skipping is neither rewarded nor penalised, so sitting out preserves my chips. Past spins are independent and give no edge.

Model's stated reason

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

Model's stated reason

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

Model's stated reason

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