Tangram Chronicles is an addictive puzzle game that’s all about shapes. The goal is to rearrange the pieces in the right order to complete the puzzle. You’ll have to think carefully about every move you make, because if you make a mistake, you’ll have to start all over again.

The best thing about Tangram Chronicles is that there are so many different puzzles. You can try to solve them all, or just pick one and focus on it. You can even play with your friends and try to beat them, or just enjoy the game by yourself.
