Questions people actually ask
before they sit down.
Is Just Blackjack real gambling?
No. Just Blackjack is simulated gambling — sometimes called social casino or fake gambling. The chips are a score. They have no cash value, they cannot be bought or cashed out, and there is no real-money wagering anywhere in the app. Nothing you win or lose is money.
Is Just Blackjack free to play?
Yes. The game is free to download and free to play. You start with 2,500 chips, there is no buy-in to sit down at the table, and a daily reward tops you up every day you show up. If you run out of chips you rebuy for free.
Can I play blackjack free online without downloading anything?
Yes. There is a real hand of blackjack running on this page and on the play-free page — the app's own table, in your browser, with no download, no sign-up and no money. You get a 500-chip stack, you set your bet, and you hit or stand.
What is simulated gambling?
Simulated gambling is a casino game played with virtual chips that have no cash value. You cannot deposit money, you cannot withdraw money, and the chips cannot be exchanged for anything outside the game. It is the format used by social casino apps, and it is what Just Blackjack is. The long version is here.
What blackjack rules does Just Blackjack use?
A six-deck shoe, dealer stands on all 17, blackjack pays 3 : 2, double on any two cards, split up to four hands, insurance offered against a dealer ace, and late surrender. These are standard six-deck rules and they are the same rules the strategy coach is built against.
What does a provably-fair blackjack shoe mean?
Every shoe is shuffled from a seed, and a cryptographic commitment to that seed is published before the first card is dealt. When the shoe retires you can export it and check that the order of the cards matches the commitment. The game cannot re-shuffle against you mid-shoe, and it does not adjust the deck based on your balance or your bet.
Does Just Blackjack work offline?
Yes. The whole game runs on the device, so you can play on a plane or with no signal. You only need a connection to sync your leaderboard position and claim online rewards.
Can I win real money playing Just Blackjack?
No, and you cannot lose any either. There is no cash in or cash out of any kind. Practice or success at a simulated casino game does not imply future success at real-money gambling.
Sit down.
Free to play, free to lose. Two thousand five hundred chips are already on the table.
