Total of (approx) 3000 hidey holes

On average the correct solution will be found at 1500 guesses

Everyone gets 2 guesses per post

The "traffic light" system to help locate near misses will probably reduce the guessing to a 14x14 grid after first map update, and therefore reduce total guessing by a factor of 4

Therefore 1500/2/4 = (approx) 200 posts until solution is found

If 20 people play this will take 10 days

And will take 2DividedbyZero 10 map updates at approximately 15 minutes per update = 2.5hrs of work

LOL. Thank gwd it's his time that's being wasted and not ours!

PS. Did I win yet
