Nonio

Nonio is an old and well known game. Its usually played in schools and universities on grid paper. Due to the small amount of rules and the simple layout it seems to be easy to finish, but it develops a high complexity over time and can get very addicting.

The goal is to cross out all digits on the grid and the rules are simple. You’re allowed to cross out numbers which add up to 10 or are equal. The numbers must be in the same column or row and the space in-between must be empty or filled with crossed out numbers. You’re able to cross out numbers over multiple lines as long as there are no other numbers in-between.

- the classic game starting with the numbers 1 to 19
