Futoshiki (Futoshiki)
Futoshiki is very similar to Sudoku, but with additional rules and restrictions, you must also fill the cells with numbers. Some of them are already on the field. There are mathematical signs between the cells: more or less. They must be taken into account when choosing a number that will be on a particular position. This game will greatly improve your logical thinking, and those who love Sudoku, but consider it not so difficult for themselves, will enjoy new difficulties for the mind.
