Suguru Puzzle Books

Suguru (Also called "Number Blocks" or "Tectonics" ) is a logic puzzle invented by Naoki Inaba. The puzzle consists of a grid divided into multiple outlined regions.

Each region must be filled with each of the digits from 1 to the number of cells in the region. So, a single-cell block contains the digit 1, a block of two cells contains the digits 1 and 2, and so on.

The aim is to fill the grid so that no same digit is touching, not even diagonally.

This Suguru Puzzle Book is a fun way for teens or adults to sharpen their minds and test their logic. Including 504 Puzzles of varying size and difficulty to keep you entertained for hours.
