Picture code

• Read each row’s code from left to right.
• The number tells you how many adjacent cells to leave empty □ or fill ■. For example, “2 □, 3 ■” means: 2 empty cells, then 3 filled cells.
• Click a cell to change its state.
• “Check” shows whether you recreated the picture correctly.
• “Reveal picture” lets you see the answer and return to your attempt.
• “New puzzle” changes the picture and clears your current attempt.
• Row numbers are on the left; column numbers are at the top. Fill each row from column 1 to column 8.
