Three rules constrain the board: no run of three identical colors, equal counts of the two colors in each row and column, and no duplicated full row or column. The official site identifies this logic form as Takuzu or Binary Sudoku.

Objective

Complete a grid satisfying all three color constraints.

Progression

Choose a board size and resolve cells using row and column constraints.

Guide based on official sources; this is not a new gameplay or mobile compatibility test.
