Use your computer to play Chain Sums. Or try one of the games below!
Connect all the tiles to get to target sums. At the top of the screen you find different target numbers that you must get too. You can do this by moving the various tiles: click a tile and a desired location to move that tile. Try to create groups of tiles to get to the target numbers at the top of the screen to clear the level.
Click a tile and a desired location to move the tile. Clicking two tiles swaps their location.
