Futoshiki, also known as Hutosiki, is a new logic puzzle game from Japan that is almost as popular as Sudoku. Futoshiki is like Sudoku except there is no box
constraint. Instead, you have greater than and less than
signs indicating the relationship between certain cells
in the puzzle.
Fill in the 5x5 grid with the numbers from
1-5 once per row and column and in obeyance with any
inequalities shown. In futoshiki there is only one valid
solution per puzzle that can be reached through logic and
clear thinking alone!
We can generate an almost infinite number of Futoshiki games for kids (aged 8 and up) and adults. Difficulty levels can range from beginners to experts,
with a grid size of 4x4 (Kids), 5x5, 6x6 or 7x7. Click on the links below to see some samples.
To solve a Futoshiki, combine the three strategies of Sudoku (Excluding, Situating and Securing) with the following
IF A < B THEN
The candidates for A will be less than the largest candidate for B.
IF A > B THEN
The candidates for A will be greater than the smallest candidate for B.
For example: suppose the candidates for A are 245 and for B 124.
If A < B then A=2 and B=4.
Look for chains of boxes linked by inequality signs.
