Sums for Windows 8 is a small Windows 8 game app. The goal of the game is to collect maximum sums of points. In each turn, select a token by tapping on a tile from your row or column. Each collected tile awards you with its value. The game is over when a player cannot collect any more tiles. Choose a round trip game to play the board twice, once rows, and once columns. You can replay an existing board (games by code), then choose the direction and who starts. You may set the challenge level. In more difficult levels, the computer thinks longer in the background while you play your turn, so move fast.
