Zerosum is a puzzle game that is easy to learn but difficult to master, where players attempt to remove as many tiles as they can before their chances run out by matching at least three blocks with the same number in a column or row.

Click on a block to select it, then select an adjoining tile to move it over to the new spot. This block will then change to a number which is the sum of the previous two tiles, with numbers going above nine starting the count from zero again. One tile will then be taken from your stock to replace the blank spot vacated by the original block, as indicated in the next tile indicator on the right side of the screen.

As the level counter increases, more chains and matches are needed to fulfil the extend quota, which then increases your stock count by one. When burst mode is activated, tiles do not have to be in a straight line to be considered a valid match. Metallic tiles have numbers which cannot be changed, blocks encased in ice has to be freed by removing a tile next to it, and numbers in rounded tiles are increased by one after every turn.

There is a short advertisement to sit through before the game will load.
