Plus or Minus
Show canned hints
The six-letter entries can be filled into the grid as is.
The legend to the right of the grid says that of the 36 squares in the grid, 3 are of one type and 5 of another. The squares indicate what happens to across and down answers passing through them.
The four-letter entries can also be finagled into the corresponding rows and columns, but with two extraneous letters. Some of these correspond to the 8 squares that have minuses.
When an entry hits a plus as it enters a square, the letter in that square is appended to the entry as normal. When an entry hits a minus, the letter in that square is instead removed from earlier in the entry. This cancels out an earlier plus, accounting for the four-letter entries.
To extract, examine the 8 special squares.
