Put your logic skills to the test with 400 Hard to Very Hard Binary puzzles on 7×7 grids.

Binary puzzles are solved using only the digits 0 and 1. Your task is to fill every empty cell while following several interconnected rules.

No row or column may contain more than two identical digits next to one another. Because the grid has an odd number of cells, each row and column must contain three of one digit and four of the other. In addition, no two completed rows may be identical, and no two completed columns may be identical.
