Find all of the blocks. Beside each row/column are listed the lengths of the runs, in order, of the blocks in that row/column. What are the numbers for? The numbers show you how many blocks appear together in each Row/Column.
This is the start of the puzzle.
Column 4 has a 4 clue, and no matter where these 4 are, these squares must be blocks.
These squares can all be determined from the clues for each of the rows involved.
These two squares must be blocks to complete the clues in the respective columns.
These squares must be crosses to complete the respective rows and columns.
These squares must be blocks to complete the clues in Column 1 and Column 2.
These squares must be crosses to complete the respective rows and columns. The puzzle then completes once Column 4 is set correctly.
The completed puzzle.
