How to play Binary
Just 0s and 1s, but they have to be perfectly balanced.
The rules
- Fill every square with 0 or 1.
- No more than two of the same digit next to each other in a row or column.
- Each row and each column has as many 0s as 1s.
- No two rows are the same, and no two columns are the same.
A quick example
Two 0s side by side force a 1 next to them.
Tips
- Look for pairs (0 0) and gaps (0 _ 0): the squares around them are forced.
- When a row already has its half of 0s, fill the rest with 1s.
- Near the end, compare almost-finished rows so no two turn out identical.
