How to play

Solve the puzzle by placing blocks on the grid so that each row and column get spans of the correct length as indicated by the label guides. You can also place crosses in the grid to help you remember cells you have eliminated. Each time you touch the grid the puzzle will highlight the corresponding row and column and show you the spans they must contain. Use the arrow tool to investigate the grid without modifying cells, use the block tool to toggle blocks on/off and the cross tool for crossing out. The following two tools fill the remaining empty cells in a row or column with your current selection (arrow+fill clears the cells). The last tool introduces a semitransparent layer showing the hints for every row and column.
