About Binary Sudoku (Takuzu / Binairo)

Binary Sudoku, also known as Takuzu or Binairo, is a logic puzzle where you fill a grid using only 0s and 1s. Like traditional Sudoku, it requires pure logical deduction - no guessing needed. Our Binary Sudoku+ version adds extra constraint symbols between cells for an additional challenge.

Binary Sudoku Rules

• Balance: Each row and column must contain equal numbers of 0s and 1s.
• No Triples: No more than two consecutive 0s or 1s in any row or column.
• Uniqueness: No two rows can be identical, and no two columns can be identical.
• Plus Constraints: "=" means adjacent cells are equal; "x" means they differ.

Solving Strategies

Start by looking for cells where only one digit is possible. Common patterns include:

• Triple Prevention: If you see "0 0 _" the blank must be 1 to avoid three 0s.
• Sandwich Pattern: If you see "0 _ 0" the middle must be 1.
• Balance Counting: If a row already has three 0s (in a 6x6), remaining blanks must be 1s.
• Constraint Chains: Use "=" and "x" symbols to deduce connected cells.
