SumJong

Math and Mahjong combined. Create valid sums with free tiles.

1. 1

   Slide all the tiles in one direction at a time - up, down, left or right.

2. 2

   Two tiles with the SAME number join together when they touch.

3. 3

   Two 2s make a 4. Two 4s make an 8. Keep going.

4. 4

   A new tile appears after every move, so the board fills up.

5. 5

   Make the target tile before you run out of space.
