How It Works

This engine calculates Expected Value (EV) for every action: the average profit/loss per unit bet over many hands.

A positive EV means the action is favourable. The engine uses full basic strategy adjusted for the rules you set above.

Changing deck count, soft 17, and double after split all affect the EV calculations. Try toggling them to see the difference.
