Sum is a simple math-based, crossword-style game for iPad. Play with your Game Center and Facebook friends in this fun multiplayer game.
Its as simple as:
1. With each move, add a row that interconnects with other rows.
2. You cannot repeat colors in a row.
3. All rows must add up to multiples of the games base number.
The game ends when there are no more moves to be played. If you have tiles left and no moves, you will be forced to resign and lose. So watch your tiles and make sure you dont run out of moves!
