## What is Futoshiki Japanese Puzzles?

Enjoy this challenging Japanese puzzle game.

Rules listed below!  Enjoy.

Futoshiki is a fun puzzle game. The rules of futoshiki are as follows:

You start with a 5 x 5 grid.

There are also greater than and less than signs between certain cells on the grid.

The aim is to fill each row and column with 1 - 5 exactly once (assuming a 5 x 5 grid) - this rule is familiar from sudoku.

However there are no box regions to concern you as in sudoku.

The big difference is the inequality signs, and you must obey these in your answers. For instance if you have that a cell is greater than the one next to it, then you know the left cell cannot be 1 and the right cell cannot be 5.

Use logic alone to deduce where each number goes and solve the puzzle.

## Key features

- 5x5 grid puzzles

### 4/5 — Simple but fun

*2022-12-26*

I like not having pencil marks and being able to just use my brain. It makes for a different experience. But quite a few of the puzzles have incorrect solutions. 1>3 and all sorts… I can’t get the app support link to work so I’m just writing here so Andrew can see there’s a problem.

### 1/5 — Missing very basic features

*2020-04-17*

I’ve been looking for my ideal version of a Futoshiki app, and this is by far the worst one I’ve tried. No pencil feature at all, and the method of filling in the squares is ridiculous (tap multiple times to shuffle sequentially through each option)
