While there's a link to the rules on that page, I will go ahead and explain them here as well. Your goal is to write one letter in each cell of the grid so that those letters can be used to spell the words listed below the grid, starting in one space, and then moving one space at a time up, down, left, or right (and not diagonally). Each word starts in the numbered space indicated, and the first move must be in the direction indicated by the arrow; the rest is for you, as the solver, to determine. In the example puzzle below, for instance, the word ONE must be spelled by starting with cell 1 for the first letter, moving one cell to the left for the second letter, and then moving one more cell in some direction for the final letter. Some letters will be used in more than one word (such as the O in ONE and TWO, or the R in THREE and FOUR), but no cell may be used more than once in the same word.
The actual puzzle (linked to above in the first paragraph) involves the names of Housepets! characters. (Note that punctuation and spaces, such as in MR. BIGGLESWORTH, are to be ignored, and not entered in the grid.) If you can prove that you've solved it (preferably by PMing me -- don't spoil the fun for others!), then I'll honor your puzzle-solving efforts in my signature! I can't think of a better reward at the moment, so settle for that.
[edit]I almost forgot to thank Buckdida for his Housepets! information thread, which greatly assisted in this puzzle's construction.[/edit]
. I might try it later. Nicely done, mathgrant.
