Modulot is a fun and addictive puzzle based on number additions and their modulus 10 values.

The aim of the game is plain and simple... Try to clear the grids!

Select an empty field in the grid and add all surrounding/adjacent numbers.
Try to match the last digit (modulus 10) with the given next modulus value.
If the match is valid all cells of the addition will be cleared.
If there is no match the given next modulus value will be placed at the previously selected empty field.

There is always a match possible... it's up to you to find it :)
