3987: Fizz Buzz by BeRo

In this puzzle from BeRo, only the starting cell of each answer was given, and we were told to simulate the counting game of Fizz Buzz when filling the grid. This was to be done by changing the direction of entry by 90 degrees each time that a letter value divisible by either 5 or 7 was reached. The relevant letters were therefore E,G,J,N,O,T,U and Y. Initially, only the first letter of an answer could be positioned with certainty, but when enough of these had been placed, some partial or complete answers could be entered in the grid. The highest concentration of starting cells was in the top left corner, so Gregson suspects that this is where most solvers will have made initial progress.

Unchecked letters, in grid order, spelt out CHAMPERS (a synonym of FIZZ) and DRAIN (a synonym of BUZZ). Solvers and forfeit-payers were therefore invited to DRAIN CHAMPERS, although on this occasion Gregson elected to celebrate the completion of an enjoyable puzzle by quaffing something brewed a little closer to home.
