Sum it Up is a number puzzle where you count in your head and eliminate blocks. You will play using regular blocks with numbers, bombs, lasers, negation blocks and more. The objective in the game is to drag to select chains of blocks that match specified sums. In Sum it Up you are challenged with over 100 levels with puzzles of increasing difficulty. You can also play the game in classic mode where the number board is kept constantly filled, or you can play in drop-down mode where you should try to keep the board as clean as possible while blocks keep falling from the top. Longer sums give higher score in all three game modes.


You may also play in online dominance mode against your friends or other players. This is a fun twist where you should reach dominance on the board in turn-based games. Try to outsmart your opponent and capture all the blocks. Sum it Up also includes achievements and leaderboards.
