In the game, there are two sets of robots: A blue and a gold team with two robots each. The players can move the robots around by dragging them with their fingers. Throughout the game, boxes with numbers inside drop down from the top of the screen. The robots can catch the boxes on their head. However, only the first box will stick to its head and only the numerical value of this box will count. This is marked by the outer edges of the box turning the same colour as the robot. Further boxes landing on top of the first box do not count. If the players want to remove a box from the head of the robot, they simply need to shake the robot from side to side and the box will detach from its head.

Points and time

Once each of the two robots of the same team has a box attached to their head and these two numbers add up to the target number displayed in the stomachs of the robots, the two boxes will disappear from their heads and a new target number will be displayed in their stomachs. For each successful calculation, the players are rewarded with one point. The players’ total amount of points is always visible under the right dome at the top of the screen. Under the left dome, a timer is displayed which shows the amount of time that the players have been playing the game. The timer offers the players the opportunity to see how fast they can collect a certain amount of points and then try to beat that record in another game.
