Binary Game Guide

📖 About

Binary (also known as Takuzu) is a deceptively simple logic puzzle that tests your pattern recognition skills. Fill a grid with 0s and 1s following three elegant rules: no more than two identical digits can be adjacent, each row and column must contain equal numbers of 0s and 1s, and no two rows or columns can be identical. Simple to learn, challenging to master!

🎯 Objectives

Complete the grid with 0s and 1s so that no three consecutive cells contain the same digit, each row and column has equal numbers of each digit, and all rows and columns are unique.

🎮 How to Play

Click cells to fill with 0 or 1. Rules: 1) No more than two same digits adjacent, 2) Each row and column has equal 0s and 1s, 3) No two rows or columns are identical.

⌨️ Controls

Click a cell to cycle through: empty → 0 → 1 → empty. On mobile, tap to toggle between states.

⚙️ Game Mechanics

  • No three consecutive cells can contain the same digit
  • Each row must have equal numbers of 0s and 1s
  • Each column must have equal numbers of 0s and 1s
  • No two rows can have identical patterns
  • No two columns can have identical patterns

Features

  • Grid sizes from 6×6 to 14×14
  • Auto-check for invalid patterns
  • Highlight matching rows/columns
  • Undo/redo functionality

💡 Tips

  • If two same digits appear, the next must be opposite
  • Count remaining 0s and 1s in each row/column
  • Look for rows/columns that are nearly complete
  • Compare partial rows to find unique patterns

Frequently Asked Questions

Why is it called Binary?
The puzzle uses only two digits (0 and 1), representing binary code. It's also known as Takuzu or Binairo in different regions.
What happens if I create three consecutive same digits?
That's an invalid move! The puzzle will typically highlight this error. You need to change one of the three cells to fix it.
Can I use the uniqueness rule to my advantage?
Absolutely! If filling a cell would make two rows identical, that cell must be the opposite value. This is a key advanced strategy.
Is there always a unique solution?
Yes, well-designed Binary puzzles have exactly one valid solution that can be found through logical deduction alone.
