Masyu Game Guide

📖 About

Masyu is the elegant Japanese logic puzzle that tests your spatial reasoning! Draw a single continuous loop that passes through every pearl on the grid. White pearls require the loop to pass straight through, while black pearls require a turn. This pearl placement creates logical constraints that make every puzzle solvable without guessing—pure deduction from start to finish!

🎯 Objectives

Draw a single continuous loop that passes through every pearl. At white pearls, the loop must go straight through (no turn). At black pearls, the loop must turn. The loop cannot cross itself or branch.

🎮 How to Play

Click on edges between dots to draw line segments. The loop must pass through all pearls. At white pearls, go straight through. At black pearls, make a turn.

⌨️ Controls

Click on the edges between grid dots to draw line segments. Click again to remove a segment. Build the loop section by section until it forms a complete closed path.

⚙️ Game Mechanics

  • Single continuous loop required
  • Loop passes through all pearls
  • White pearls: go straight through
  • Black pearls: must turn at pearl
  • Loop cannot cross or branch

Features

  • Pure Logic - No guessing needed
  • Elegant Rules - Simple to learn
  • Visual Deduction - See patterns emerge
  • Multiple Sizes - Easy to expert

💡 Tips

  • Black pearls must turn - plan corners around them
  • White pearls need straight paths - avoid blocking both directions
  • Look for pearls near edges - they constrain the loop
  • Build the loop section by section, connecting as you go

Frequently Asked Questions

What do white pearls require?
White pearls require the loop to pass straight through them—the loop must enter and exit in opposite directions (no turn at the pearl). However, the loop CAN turn immediately before or after the white pearl.
What do black pearls require?
Black pearls require the loop to make a turn at that exact position. The loop must enter and exit at a 90-degree angle, forming a corner at the black pearl.
Can the loop cross itself?
No! The loop must be a single continuous path that never crosses itself or branches. It's one closed curve that visits every pearl exactly once.
Is guessing ever needed?
No! Well-designed Masyu puzzles can be solved entirely through logical deduction. If you're guessing, look harder for the logical constraints you may have missed.
