### Puzzle 405 (Creek) [Treasure hunt]

June 13, 2012

This is a Creek puzzle, with a twist. One of the grid squares has treasure in it, though its location is not given. A number in a grid cell gives the length of the shortest path to the treasure going through adjacent unshaded cells. The path length is computed as the number of grid cells used, including the two cells with the clue and the treasure. Cells with a number or treasure are unshaded.

Puzzle 397

Almost went an entire year without one of these… given that, perhaps a reminder is in order: I’ve always used a variant on the rules which does not require every room to be visited. This puzzle is no exception.
