Share this page to Google Classroom


Takuzu, also known as Binairo or Binary Sudoku, is a logic puzzle game that involves filling a grid with black and white tiles according to certain rules. The goal is to create a grid where each row and column contains an equal number of black and white squares and no more than two consecutive identical colored tiles appear in either row or column.



Color every square either black or white, in such a way that:
  • no three consecutive squares in a line, horizontally or vertically, are the same color
  • each row and column contains the same number of black and white squares.

Left-click in an empty square to turn it black, or right-click to turn it white. Click again in an already-filled square to cycle it between black and white and empty; middle-click to reset any square to empty.
