On this page you can learn all about suguru!


Suguru, also known as cijferblokken or number blocks, is a creation of Naoki Inaba from Japan. Naoki Inaba is a well-known puzzle designer.

These suguru puzzles only have a few simple instructions, but they can be extremely challenging. At first sight they resemble sudoku puzzles.

You have a grid which is subdivided into shapes. Each shape has 1 to 5 cells in size. Now fill the grid so that each cell contains a digit from 1 to 5. So for example a 3-square shape may only contain the numbers 1, 2 and 3. A 5-square shape should contain the numbers 1 to 5. No same digit appears in any neighboring cell, not even diagonally.

There is no fixed order to place to digits, but you have to use thinking strategies. Suguru is not a game of trial and error.

To get you started some cells already contain a number. Let’s try it!
