Welcome to Cubisum! Let's go through a brief tutorial.
The goal of the game is to match all the numbers on the boxes.
Click or tap on a box to increment the numbers of its neighboring boxes (Right click or long press to decrement).
Boxes can be clicked up to four times before resetting. The number of dots/box color indicates how many times the box has been clicked. Test it by clicking below!
There is a new Cubisum every day at 5PM your time.
Try out the different game modes! Play alone in Classic, compete with others in Public Multiplayer, or challenge your friends in the Play with Friends multiplayer.
