How to Use the Blackjack Calculator

This tool is designed to help you learn and master Blackjack's "basic strategy." Basic strategy is a set of mathematically proven rules that tells you the optimal play for any hand you are dealt against any dealer up-card. Following this strategy minimizes the house edge and gives you the best possible odds of winning over the long term.

Using the Tool is Simple:

Select Your Hand: Click on the two cards that match your starting hand.
Select the Dealer's Card: Click on the one card the dealer is showing.
Get the Correct Move: The calculator will instantly display the mathematically correct move—Hit, Stand, Double Down, or Split.
