Suguru Game Guide

📖 About

Suguru is a number placement puzzle where you fill regions with digits. Each region's size determines which numbers to use (a 4-cell region needs 1-4). The key rule: no two adjacent cells (including diagonally!) can contain the same number. A fresh twist on number logic!

🎯 Objectives

Fill each region with numbers 1 through its size, ensuring no adjacent cells (orthogonally or diagonally) share the same number.

🎮 How to Play

Fill each region with numbers 1 through its size. Identical numbers cannot be adjacent (including diagonally). Use logic to deduce each cell's value.

⌨️ Controls

Click a cell and enter a number from 1 to the region's size. Each region must contain all numbers from 1 to its size exactly once.

⚙️ Game Mechanics

  • Each region must contain numbers 1 through its size
  • No two adjacent cells can have the same number
  • Adjacency includes all 8 neighboring cells (diagonals count!)
  • A 1-cell region can only contain 1
  • A 2-cell region needs numbers 1 and 2

Features

  • Multiple grid sizes and difficulties
  • Auto-check for duplicate adjacencies
  • Highlight same-number neighbors
  • Undo/redo functionality

💡 Tips

  • Start with small regions (size 1-2)
  • Look for cells that can only be one number
  • Use elimination based on adjacent numbers
  • Check all 8 neighbors when placing numbers

Frequently Asked Questions

How is Suguru different from Sudoku?
Suguru has irregular regions instead of 3×3 boxes, and most importantly, diagonal adjacency matters! Two cells touching diagonally cannot have the same number.
What does region size mean?
A region with 3 cells must contain numbers 1, 2, and 3 exactly once each. The region size determines the number range.
Why do diagonals matter?
Unlike Sudoku, Suguru considers all 8 neighbors around a cell. This means corner-adjacent cells also cannot share the same number.
What's the best starting strategy?
Find single-cell regions first (they must be 1). Then look for cells surrounded by different numbers that force a specific value.
