How to Play Binairo

1. Objective: Fill the grid with black and white circles following three simple rules.
2. Rule 1 - Equal Numbers: Each row and each column must contain an equal number of white and black circles.
3. Rule 2 - No Three Adjacent: More than two circles of the same color can't be adjacent (horizontally or vertically).
4. Rule 3 - Unique Rows/Columns: Each row and column is unique (no two rows or columns are identical).
5. Gameplay: Click a cell to cycle through: empty → black → white → empty. Use the color buttons or click directly on cells.
6. Winning: When all cells are correctly filled following all rules, you've solved the puzzle!

Strategy & Tips

• Start with Equal Numbers: Since each row/column must have equal black and white, if a row has 3 black circles, it must have 3 white circles too.
• Watch for Adjacent Patterns: If you see two same colors together, the next cell must be the opposite color to avoid three in a row.
• Use Uniqueness: If a row or column would become identical to another, that placement is invalid.
• Check All Constraints: Always verify that your placement doesn't violate any of the three rules.
