Just you and the dealer. No internet, no ads, no pressure.
Blackjack 21 is a polished, single-player card game you can play absolutely anywhere: on a flight, on the subway, or on the couch at midnight. No WiFi required, no sign-up, and no ads to sit through. Deal the cards and play.
We made this for people who love blackjack but are tired of pushy casino apps. The deal is honest, the chips are generous, and your game is never interrupted.
A FAIR, HONEST DEAL
Most casino apps ask you to trust them. We show you how it works.
- Every card is shuffled by your device's secure random number generator
- The dealer follows strict, published rules you can read any time
- A built-in Fair Deal panel explains exactly how each hand is dealt
- No rigged streaks, no pay-to-win, no tricks…

blackjack-apple-6784697889What the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
These are really on sale; we just can’t tell from the name whether they recur.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
