Binairo: fill the grid with 0s and 1s
Binairo turns number placement into a clean deduction puzzle, and the grid starts partly solved so every move has to fit the pattern already on the board. As a Puzzle title, it asks you to think in lines and columns, not in guesses, with a no download and no signup setup.
Balance every row and column
Your main job is to place zeros and ones until each row and column contains the same amount of both symbols. The catch is that you cannot let three matching digits touch in a line, so every new move has to respect both the balance rule and the spacing rule.
Start from the filled clues
The visible digits are your anchors, because the empty cells have to be solved around them. That makes each board a logic exercise: one placement can force a whole stretch of the grid, and a wrong idea tends to clash with the existing pattern fast.
For fans of grid logic games
If you enjoy deduction puzzles like Sudoku, Classic Sudoku Puzzle, or Hexalau, this one scratches the same pattern-reading itch with binary symbols instead of numbers. IQ Test: Exercise Your Brain! fits the same brainy mood when you want another logic challenge after finishing a board.
