Basic Strategy Chart

The mathematically optimal play for every hand, based on your total and the dealer's upcard. Hover or tap a cell for a plain-English explanation.

This chart assumes common conditions: 4–8 decks, dealer stands on soft 17, doubling after split allowed. Rules vary slightly by casino — see our Variants page for how that changes things.

Why Basic Strategy Matters

Basic strategy is the set of plays, worked out through computer simulation of millions of hands, that minimises the house edge for any given rule set. It doesn't guarantee you'll win a given hand — nothing can — but it's the difference between playing against a house edge of roughly 0.5% and one closer to 2% from guesswork alone. See exactly what that means on our Odds & House Edge page.
