BLACKJACK Free unlimited online simulator & trainer

Basic strategy guide

Free blackjack simulator and trainer with unlimited chips

Open Blackjack is a free blackjack simulator you play online in your browser, on computer, tablet and phone, with no download and no sign-up. It is also a complete blackjack trainer: a basic strategy coach that corrects you in real time, card counting practice with 25 ready-made systems or one you create yourself, and table rules you can set up like a real casino.

You bet virtual chips only, so there is no real money and no deposit. Chips are unlimited: if you run out, you get 1000$ again and keep practising for as many hands as you like, without risking anything.

The table plays like casino blackjack, the game of 21: a shoe of 1 to 8 decks with a cut card, blackjack paying 3 to 2, insurance paying 2 to 1, doubling, splitting and surrender, and a dealer who stands or hits on soft 17 depending on the rules you choose.
