Subiku : the binary sudoku play online

The Subiku is a number puzzle game that follows the same logic as Sudoku, Takuzu, the picross, or the 2048. Faster than a Sudoku, the grid can be complete in less than 5min.

You'll be able to easily handle it in short runs, but you can just as well spend hours thinking about the way to solve the hardest puzzle.

This little logic game is usually a grid of 8x8 squares, containing just 1 and 0, and which must be completed according to three simple rules:

There must be an equal number of 0s and 1s in each row and column.
No more than two similar numbers next to or below each other is allowed.
No more than two rows or columns can be the same.
