Binary Sudoku
Instructions
Balance out the light and dark! Select any grid to start the puzzle. The more spaces on the grid, the more challenging it'll be! Fill in the grid so each cell contains either a white or black circle. Tap an empty cell once to place a black circle, or twice to place a white circle. Tap on the cell a third time to remove the circle completely.
Cells separated by an equal sign mean that the cells share the same type of circle. Cells separated by an x sign mean those cells do NOT share the same type of circle.
No more than two of the same circle can be next to or on top of each other. So if you see two circles of one color next to each other or on top of each other, place the opposite color on both sides of them!
If you get stuck, click the lightbulb in the upper right corner to get a hint. You start with 5 hints. If you use up all of your hints, you can watch an ad to get more.
