It's a game where you have to combine blocks of positive and negative numbers to get horizontal or vertical groups that the sum is equal to 0, inside a 5x5 grid, before the board is completely filled.
With time more blocks will appear and you will have to predict your next step very carefully. If you make chain reactions you will get more points.
Also, there are leaderboards so you can see your rank against your friends and others globally.
