- Valgetal Tables
- License: Shareware
- Price: 12


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 size of the container, which immediately makes it harder to control successive blocks precisely.
