What is Futoshiki?

Futoshiki is a logic puzzle game that started in Japan and has been growing in popularity. Translated, it means "not equal".

How to play Futoshiki?

Futoshiki rules are simple. You must place the numbers 1 through 5 in each of the five rows and columns, neither of which can contain the same number twice. At the start of the game some numbers are given to you. Additionally, your number placement must follow the greater than and less than signs that are on the board. Futoshiki puzzles tend to be easier than Sudoku puzzles as they are smaller; Futoshiki uses a 5x5 grid and Sudoku uses a 9x9 grid. They are, however, a fun and challenging game.
