How to Play
- Tap any empty cell to cycle its value: Empty → 0 → 1 → Empty.
- No Triples: You cannot place more than two identical digits next to each other horizontally or vertically (e.g., 0-0-0 is forbidden).
- Balanced Lines: Each row and column must contain an equal number of 0s and 1s (e.g., three 0s and three 1s in a 6×6 grid).
- Unique Lines: No two rows can be identical, and no two columns can be identical.
- Fill the entire grid correctly without breaking any of the three rules to win.
About Binairo (Takuzu)
Binairo, also known as Takuzu or 0-1 Logic, is a binary deduction puzzle. Despite using only two symbols, Binairo generates deep logical interactions. Every placement creates a ripple of constraints across horizontal and vertical lines, rewarding systematic reasoning without ever relying on luck.

Binairo Strategy and Tips
1. Avoid Triples (Pairs and Sandwiches)
Whenever you see two identical digits next to each other (like 0 0), place the opposite digit on both ends (1 0 0 1). When two identical digits are separated by an empty space (like 1 _ 1), the space between them must be the opposite digit (1 0 1).
2. Count Remaining Digits
In a 6×6 grid, every row and column has exactly three 0s and three 1s. Once a line has three 0s placed, immediately fill all remaining empty spaces in that line with 1s.
3. Eliminate Duplicate Lines
Near the end of a puzzle, check rows or columns that are almost complete. If completing a line one way would make it identical to another already-finished line, choose the opposite combination to keep every line unique.
Why Binairo strengthens analytical thinking
Binairo teaches you how simple local rules combine into global constraints. Regularly solving binary logic grids trains your ability to recognize patterns quickly and deduce logical consequences with high precision.

What is the difference between Binairo and Takuzu?
Binairo and Takuzu are different names for the exact same classic 0-1 binary logic puzzle. The rules and deduction strategies are identical.
Why can't I place three 0s or three 1s in a row?
The rule forbidding three identical consecutive digits (no triples) is the core engine of Binairo deduction. Whenever you see two identical digits next to each other, you immediately know the adjacent cells must be the opposite digit.
