Finding Sets

一个益智游戏卡。这是简单的，但不容易！

A puzzle game with cards. It is simple, but not easy!

Each game has a stock of 81 unique cards. Nine cards are always shown to the player.

Look for sets of three cards. A set is three cards where each attribute (color, filling, shape, count) is the same for all three cards or completely different for each card. In the shown cards, at least one correct set is always present.

If you don't know the rules, the app explains them using pictures. The tutorial in the app can help you start.
