Step 1 This is the start of the puzzle.
Solve this puzzle for yourself at the same time.


Step 2 Column 2 has a 4 clue, and no matter where these 4 are, these squares must be Black.


Step 3 The 2 clue in Row 4 cannot reach these two squares, so they must be crosses.


Step 4 Column 4 has a 2 and a 1, and as both cannot fit in the three squares above the cross, the 1 must be this square.


Step 5 The 2 clue in Row 5 cannot reach these two squares.


Step 6 The 4 clue in Column 2 completes with this square.


Step 7 We've now found the 1 clue in Row 1, so these squares are crosses.


Step 8 Wherever the 3 is in Column 3, these squares must be Black.


Step 9 We've found the 2 clue in Row 4, so this square is a cross.


Step 10 Which means that these squares are the 2 clue from Column 1.


Step 11 We've found the 2 from Row 2, so this square must be a cross (otherwise there would be 3 Black squares for a 2 clue).


Step 12 These squares must be the 2 from Row 1.


Step 13 We've found the 1 in Column 5, so these must all be crosses.


Step 14 These squares are all obvious. Row 2 must be a Black square to satisfy the 1 clue. Row 3 must be a cross as we've found the 3 Black squares required. Row 5 must be Black to complete the 2 clue.


Step 15 The completed puzzle.
