How to play

  • The numbers to the left of each row and above each column are clues: in order, they give the length of each run of filled cells in that row or column, with at least one empty cell between runs.
  • Every puzzle is generated by the game and has a unique solution you can reach step by step through logic alone, with no guessing. Fill every cell that belongs to the picture to finish; crosses are just notes for yourself.
  • With "Show mistakes", a wrong fill or cross is rejected and counts as a mistake, and that cell shows the correct answer. "Free mode" doesn't check anything, and the puzzle completes automatically once every fill is correct.
  • Hint reveals one cell that can be deduced from the current board. Each hint and each mistake adds a 10-second penalty. You can undo and clear the board, and this device keeps your fastest time for each size.

Worked examples and tips

On a 10×10 board, one row's clue is 8. Whether the run starts at cell 1 or cell 3, cells 3–8 are always filled, so fill those 6 cells first and leave the 2 cells at each end for now. Once the row has its run of 8, the remaining 2 cells must be empty and can be crossed out (with "Auto-cross" on, this happens automatically).

Detailed rules and controls

Controls
  • Tap a cell to fill or cross it with the current pen, and tap it again to erase. Press and drag to keep marking along a row or column.
  • On a computer, right-click to cross a cell. With a keyboard, arrow keys move, Space or Enter marks, X crosses, Delete erases, and M switches between fill and cross.
  • If the cells are too small, enlarge the board: drag the clue area or use two fingers to move it, and pinch to switch between the enlarged and full view.
  • The current row and column and their clues are highlighted; clue numbers that are already satisfied fade out.
Solving basics
  • When the clues plus one gap between each add up to exactly the row length, the whole row can be filled in straight away.
  • When a run is longer than half the remaining space, the overlapping cells in the middle must be filled wherever it goes.
  • Once a row's filled cells already match its clue, none of the other cells are filled, so you can cross them all out.
