Welcome to Puzzle Twenty-one; a whole new puzzle challenge! Puzzle 21 - Card Challenge is an original puzzle game for iPhone that combines elements of Solitaire, Patience, and Blackjack. In this game, your goal is to get the most points from a deck of cards by making columns that add up to 21.

Unlike traditional gambling games, Puzzle 21 - Card Challenge focuses on skill and strategy. You can take one card at a time from the deck and assign it to a column. The challenge is to make the sum of the cards add up to twenty-one without going over.

The game offers a unique scoring system where Aces are worth 1 or 11 points, and getting a Twenty-one doubles the points. If you manage to get a Blackjack (a Twenty-one with only 2 cards), you earn triple points!

Puzzle 21 - Card Challenge provides an exciting gameplay experience with just the right mix of skill and luck. It offers depth with unlockable rules that allow you to earn more points and achieve higher scores. You can also compete with your friends on the leaderboard and strive to become the best card sharp.

Additionally, the game allows you to customize your experience by unlocking new Decks, Card Backs, and Tables. The inclusion of haptic feedback adds a sense of immersion to the gameplay, enhancing your overall gaming experience.

If you're looking for a new and familiar puzzle game for your iPhone, Puzzle 21 - Card Challenge is definitely worth a try. Challenge yourself, test your skills, and see if you can earn the most points with a deck of 52 cards!
