This math game challenges you to practise the multiplication tables by controlling the placement of falling numbers. If you create a vertical column of two blocks, the number on top must be the multiplication of the number below it and the number you have chosen in the main menu; if it isn't, you are penalised by a reduction in the Taille of the container, which immediately makes it harder to control successive blocks precisely.

If you have chosen, for example, to practise with "8", and you place a 5 on the bottom, then you must put a 40 above it to complete the equation: 5 x 8 = 40.

There are 20 progressively difficult levels to begin with. A high-score Plateau lets you post your name and results. The game's name means ''falling numbers'' in Dutch: English, Friesian, Dutch, German and Spanish interfaces are included.
