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