The game is easy to play but in order to completed Daily Challenges and get a really high score, you will need to plan your moves a few steps ahead.

1. Drag and drop numbers on the board
2. Build lines or squares that contain numbers from 1 to 4
3. You score every time you complete a line or a square with all numbers from 1 to 4
4. Lines and squares are cleared once all the numbers from 1 to 4 are added
5. Plan your moves in order to combine multiple lines and squares in order to get even higher score
6. Game ends when you don’t have any available moves left
