Welcome to Puzzle Twenty-one; a whole new puzzle challenge! In this original puzzle game you must get the most points from a deck of cards by making columns that add up to 21. This is NOT a gambling game. It is a solo puzzle game inspired by crossing Solitaire and Patience with the scoring system of Blackjack. ===HOW TO PLAY=== Take one card at a time from the deck, and assign it to a column. Attempt to make the sum of the cards add to twentyone, but don’t go over. Between getting a new card, you may choose to hit ‘Stay’ to take the points, or you can take a chance and draw the next card. Aces are worth 1 or 11 points. Getting a Twenty-one is worth double points, getting a Blackjack (a Twenty-one with only 2 cards) is triple points! The goal: Get the most points with a deck of 52 cards. === FEATURES === ● Excitement: Just the right mix of skill along with the thrill of getting lucky, but without a gambling component. ● Depth: Unlock new rules that allow you to earn more points and get even higher scores. ● Compete: See how you measure up on the leaderboard. Beat your friends’ scores and become the best card sharp. ● Customise: Unlock new Decks, Card Backs, and Tables. ● Haptic feedback adds a sense of immersion (this can be turned-off in the settings).

I wanted this game so long and others were lacking this or that or small cards or no take button. And a lot of other versions have shady “ real cash payouts “ that I didn’t need the game. And you have no timer and thats good because I dislike games that rush you. The only thing you don’t have is the ability to play with the screen in any of four positions, only 2 ways both are portrait mode, but even that can’t be a deal breaker for me because this is just too perfect. Those that don’t know if you scroll to the bottom of the screen, not this the main one. You can see Jeffrey has poker version like this too. I got both and if you put up anymore non gambling casino stuff I’m all in. Both games are five stars. Show or tell your friends because both games deserve more attention than they have. **Developer response:** Thank you!! ### 5/5 — Nailed it Jeffrey *2024-10-22* You nailed what so many others got terribly wrong.

This app is excellent in every way. It’s visually appealing. The UI is intuitive. It’s a clever take on blackjack, and I absolutely love it. I immediately paid the fair IAP to support the developer. I highly recommend this game. I also bought this developer’s poker game, which is the same idea and design as this blackjack game. It’s also excellent. I really like having both games to get my blackjack/poker fixes. Thank you developer for making one of the best card games I’ve ever found. It’s nice to play blackjack without actually gambling real money. You came up with a great idea here, and I’m so glad I found this game! **Developer response:** Cheers! ### 5/5 — AWESOME! *2020-06-14, version 0.810* I ❤️🧡💛💚💙💜 (sorry went a bit crazy XD) what I was trying to say was I ❤️ it! (Also it’s saved me from my mum giving me questions, they are sooo hard.) I’m glad you made this game! -Abby. ### 5/5 — Awesome Game *2020-04-09, version 0.802* Fun to play ### 5/5 — Brilliant puzzler that merged two well known games. *2020-04-08* There’s not too many games where I think “oh I should have thought of that” but this is one. It’s a perfect blend of two well known card games (solitaire + blackjack). It’s easy to play and really simple to understand. As a mobile game, it’s almost perfect. Great job. ### 5/5 — Fun & Clever Combo *2020-03-24* I like it because it’s straight forward, fun, and offers short brain teasing challenges. I play it on the bus, mostly, or when I want a quick challenge while unwinding. ## Frequently asked questions about Puzzle 21 ### What is Puzzle 21 - Card Challenge?
