For fun: Futoshiki puzzles

futoshikiI love number puzzles. On Saturdays I treat myself to a lie in with the newspaper, but I have to confess that I don’t read much of the paper — my Saturday morning treat involves doing the puzzles.

Futoshiki was one of my favourites, but it no longer appears in my newspaper, so I was pleased to find this website, which generates Futoshiki puzzles of various sizes and levels of difficulty.

The basic idea is simple: if you are solving a 5 x 5 grid, you have to make sure that the digits 1 – 5 appear in each row and each column. You also have to make sure that the inequality symbols are correct, so 3 < 4 is fine, but 3 < 1 is not correct.

Seems simple? Why not give it a try?
