About the game

Numbers sit above every column and beside every row of a bare grid, and together they describe a hidden pixel picture. Each clue counts one unbroken block of filled squares in that line. When a line carries two or more numbers, the blocks are separated by at least one empty square, so a clue of 3 1 asks for three filled squares, some blank space, then one more.

You choose a difficulty and work through the grids in the collection. Nothing needs guessing: fill only what the clues prove, then test a row against its column to settle the next square. Easy puzzles close quickly, larger ones ask for patience, and the picture surfaces one confirmed square at a time.

How to play

• Read the clues over each column and beside each row: every number is the length of one run of filled squares in that line.
• Separate runs in the same line with at least one empty square.
• Click or tap a square to fill it, and clear it again if the clues do not support it.
• Work from the numbers alone, comparing rows with columns, and never guess.
