Perfect basic strategy for your exact table rules — instant, free, no signup.
This free generator builds the mathematically perfect blackjack basic-strategy chart for your exact table rules. Change the rules and the chart plus the house edge update instantly.
Pick your two cards and the dealer’s up-card:
A blackjack chart (or basic strategy chart) tells you the single best move for every hand you can be dealt against every dealer up-card. Our generator builds that chart instantly for your exact table rules — number of decks, whether the dealer hits or stands on soft 17, double-after-split, surrender and more — and shows the precise house edge those rules create.
Unlike a static image, the chart above is calculated live by a combinatorial engine, so it is always correct for the rules you select. Change any rule and both the chart and the house-edge figure update in real time.
Blackjack is one of the only casino games where your decisions change the outcome. Playing perfect basic strategy cuts the house edge to well under 1% — and in some single-deck games it can even swing in the player's favour. Guessing or playing “by feel” typically costs 1.5–2% or more, which is real money over time.
Once you have your chart, lock it into memory with the free blackjack trainer, which deals random hands and grades every decision. Playing a specific game? We publish exact charts for single deck, double deck and European (no-hole-card) blackjack, plus a dedicated house edge calculator. Everything runs in your browser, free, with no signup and no downloads.
