During the game you can use four power-ups that will help you a lot:
1. Eye
The eye option lights up only the tiles that you can move, so you can find pairs more easily.
2. Shuffle
Click here to shuffle your tiles.
3. Hint
By pressing Hint an available couple is illuminated.
4. Additional Space
During the game, you have 2 empty spaces where you can park tiles. You can also unlock a 3rd empty space.
All power-ups cost Diamonds. When you first enter the game you get 10 Diamonds as a starting gift. Should you need more, you can buy some extra from the Store.
