Futoshiki

Futoshiki is a popular Japanese numeric puzzle game similar to Sudoku. The objective is to place the numbers 1 through 5 in each row and column without any repetitions. Additionally, the relational signs (greater than or less than) placed between certain cells must be respected.

The game offers a generator with three difficulty levels: easy, medium, and hard. Each generated puzzle is guaranteed to have a single unique solution.

The aim is to fill the cells with the numbers 1 through 5, ensuring each number appears only once in each row and column. You must also adhere to the inequality signs placed between the cells. Tapping on a selected cell will toggle the notes mode on and off.
