The goal of the game is to clear the board by finding all the matches. Flip over two cards and if they match, they are removed from the board. Mismatch them and the board gets a little mixed up.

Element tokens help you clear the board. You start each level with some and as you play you randomly get more.

* Wind - flips all cards in a row / column face-up, one by one, for a bit

* Fire - removes the selected card and another matching card

* Ice - freezes the board, so a mismatch will not cause the board to change

* Earth - flips all cards face-up for a bit

Contains the following mix-up types

* Swap colors

* Swap cards
