Fillomino Game Guide

📖 About

Fillomino is the creative region-dividing puzzle from Japan! Fill every cell with a number, where same numbers form connected regions (polyominoes). Each region's size must equal the number it contains. But here's the twist: different regions of the same number CANNOT share an edge. This creates fascinating logical challenges as you balance region sizes with placement constraints!

🎯 Objectives

Fill the entire grid with numbers such that each number forms a connected region of exactly that size. Different regions with the same number cannot be orthogonally adjacent. Every cell must belong to exactly one region!

🎮 How to Play

Click a cell and enter a number (1-9). Same numbers must form connected regions. Each region size must equal its number. Different regions with the same number cannot touch.

⌨️ Controls

Click on a cell and type a number (1-9) to fill it. Connected cells with the same number form a region. Each region must contain exactly as many cells as its number indicates. Same-numbered different regions cannot share edges.

⚙️ Game Mechanics

  • Same numbers = same region
  • Region size = the number itself
  • Same-number regions can't touch
  • All cells must be filled
  • Regions must be connected (orthogonal)

Features

  • Region Division - Create polyominoes
  • Number Logic - Size equals value
  • Creative Solving - Multiple approaches
  • Unique Solutions - One correct answer

💡 Tips

  • Given numbers are anchors - regions must match their value
  • Small regions (1, 2) are easiest to place first
  • Watch for conflicts where same-numbered regions would touch
  • Count cells carefully - each region needs exactly its number of cells

Frequently Asked Questions

Can two regions with the same number touch?
No! This is the key rule that makes Fillomino unique. Two separate regions with the same number cannot share an edge (orthogonal contact). Diagonal contact is fine. This constraint is crucial for solving.
How do I know where regions end?
Each region must contain exactly the number of cells shown by its number. A region of 5s must have exactly 5 cells. When a region reaches its size, all adjacent cells must have different numbers.
What's the best starting strategy?
Look for given numbers that constrain each other. Small regions (1s, 2s) are often forced. Also look for areas where large regions must extend—there's only one way to fit them without touching same-number regions.
Can I have unfilled cells?
No, every cell must be filled with a number and belong to exactly one region. The puzzle is complete only when the entire grid is properly divided into regions following all rules.
