Each 3x3 block hides a nine-letter word: trace it through all nine of the block's letters, each step to a touching letter (diagonals too). (unfinished)
Then the blocks are one grid: find the hidden words in straight lines. (unfinished)
Then find the wrapping words, whose lines go past an edge of the grid and on from the other side. (unfinished)
The words aren't given: each clue is a word's first letter and length (S????? is six letters starting with S). (unfinished)
