Our take
Q42's elegant take on the binary puzzle (takuzu): fill the grid with red and blue tiles so that no three of a color sit in a row, every row and column holds equal counts, and no two rows or columns repeat. Rules take thirty seconds to learn, grids scale from 4x4 to challenging sizes, and it plays free in the browser with a companion game, 0h n0, by the same studio.
In one line: Sudoku-style deduction compressed into two colors and three rules.
