Blackjack strategy charts by rule set
Last updated 26 October 2026
Each chart below is solved for one exact table. The rules of that table are listed on its page.
How these charts are made
A solver computes the expected value of every legal action for every hand. Each cell shows the action with the highest expected value.
Each chart is then compared cell by cell against a published reference chart. The result of that comparison is on the chart page.
One chart is published for each set of rules. A chart solved for one table is never reused for a table with different rules.
Tables with a solved chart
The house edge column uses one convention: basic strategy with a reshuffle after every hand.

Two tables on this list are dealt under a second name. One page covers both names.
No chart page is published for Single deck, stand soft 17, DAS. A basic strategy player has an edge on those rules, so no casino deals them. The rules are selectable in the calculator and in the trainer.
Tools built on the same data
