📖 How to Play & Rules – Nonogram (Picross)
- Numbers along each row and column indicate the lengths of consecutive blocks of filled cells in that line.
- Multiple numbers (e.g., '3 1') mean there is a block of 3 filled cells, followed by at least one empty cell, then a block of 1.
- Use the tool toggle to switch between 'Fill (⬛)' and 'Mark X (❌)' for cells you know are empty.
- The puzzle is solved as soon as all required filled cells are uncovered!
💡 Strategy Tips & Tricks
- Start with lines featuring large numbers or sums that span the whole row or column.
- Mark confirmed empty cells with an ❌ so intersecting lines become much easier to deduce.
