Hi, rrrobbo, The extra letters in the clues give three words (6,2,7) in the across clues and four words (7,6,2,4) in the down clues, which should be read as a single phrase. In total, there are 31 across clues and 35 down clues. There are 32 clues with extra letters and 34 clues without extra letters. Although there are only 25 cells used in the six objects in the grid, some of these cells are in both across and down clues. I’ve checked that the grid entries for all 34 of the clues without extra letters contain at least one of the 25 cells, and none of these cells is contained in any of the entries for the 32 clues with extra letters.
