Discover the Joy of Suguru Puzzles
Unlock the fascinating world of Suguru puzzles, where irregular regions meet number logic. Master the art of Tectonics and discover why millions love these captivating number blocks challenges.
What is Suguru?
Suguru, also known as "Number Blocks" or "Tectonics," is a captivating logic puzzle invented by Naoki Inaba. Unlike traditional grid-based puzzles, Suguru features irregular regions of varying sizes, creating a unique and visually appealing challenge that tests your spatial reasoning.
The rules are elegantly simple: fill each region with numbers from 1 to the size of that region, ensuring no identical numbers touch each other—not even diagonally. This "no-touch" constraint creates intricate logical relationships that make every Suguru puzzle a delightful brain teaser.
🧩 Fun Fact: A 3-cell region contains exactly the numbers 1, 2, and 3—but where each goes depends on the surrounding constraints!

Essential Solving Strategies
Master these proven techniques to solve Suguru puzzles with confidence and efficiency
Start with Small Regions
BeginnerBegin with 1-cell or 2-cell regions as they have the fewest possibilities. A 1-cell region can only contain '1', making it the perfect starting point.
Use the No-Touch Rule
IntermediateIdentical numbers cannot touch even diagonally. Use this constraint to eliminate possibilities in adjacent cells and narrow down your options.
Apply Elimination Logic
AdvancedWhen a region is nearly complete, the remaining cells are determined. Use this cascading logic to unlock entire sections of the puzzle.
Master Regional Analysis
ExpertAnalyze how regions interact with each other. Numbers in one region can constrain possibilities in adjacent regions through the no-touch rule.
How to Solve Suguru: Step-by-Step Guide
Follow this systematic approach to master any Suguru puzzle from easy to expert level
Identify the Regions
Look at the outlined areas. Each region needs numbers from 1 up to its cell count (1-cell = only "1", 2-cell = "1" and "2", etc.)
Apply No-Touch Rule
Remember: identical numbers cannot touch each other, not even diagonally. This constraint is key to elimination.
Start Small
Begin with 1-cell regions (must be "1") and 2-cell regions (must be "1" and "2"). These provide initial placements.
Use Elimination
When placing numbers, check adjacent cells to see what numbers are eliminated by the no-touch rule.
Work Systematically
Focus on regions where you can make definitive placements, then move to areas with fewer possibilities.
Stay Patient
Suguru rewards careful analysis over guessing. Each placement opens up new logical deductions.

While both are number logic puzzles, Suguru offers a unique twist that makes it special
🧩 Suguru (Tectonics)
- Irregular regions of varying sizes create visual variety
- No-touch rule adds diagonal constraints
- Numbers 1 to region size (not always 1-9)
- Spatial reasoning focus enhances visual thinking
- Fresh challenge for experienced puzzlers
🔢 Traditional Sudoku
- Fixed 9×9 grid with uniform 3×3 boxes
- No repetition in rows, columns, boxes
- Always numbers 1-9 in every region
- Logical deduction through elimination
- Worldwide popularity and recognition
The Bottom Line: If you love Sudoku, Suguru offers an exciting new dimension of puzzle solving with its unique spatial challenges and visual variety.

💡 Pro Tips for Suguru Mastery
Expert strategies from seasoned Suguru solvers to accelerate your learning
Start with 1s and 2s
Single-cell regions must contain "1", while 2-cell regions need both "1" and "2". These provide the easiest starting points.
Master the No-Touch Rule
Remember diagonal adjacency counts! A "1" eliminates all surrounding "1s" in an 8-cell radius, not just the cardinal directions.
Use Pencil Marks
Keep track of possibilities in each cell. Cross out numbers as they become impossible through the no-touch constraint.
Practice Daily
Regular solving builds pattern recognition. Start with easy puzzles and gradually increase difficulty as your skills develop.
