One of the 12 different panels with calculations and quantities from the number range up to 100 is placed on the game board module. The punched holes have electrical contact surfaces from below. The players need to find the result on the right half that corresponds to an image or calculation on the left half. The two plugs are inserted into the holes. If the light bulb lights up, the images match; if not, the correct result of the calculation still needs to be found.
