For a similar game covering the contiguous United States, see Guesseteer.
For some reason, OS updates can occasionally delete the record of places that have been guessed. I therefore recommend that users save their guesses to a text file from time to time (using the 'Copy guesses' menu option to get the guesses onto the clipboard); this backup can then be used to restore the guesses (via 'Paste guesses from clipboard') if they should become lost.
Find it difficult to understand the concept this game, dont understand the before and after thing........ is there away of simplifying the concept about the game, just a bit confusing
This game is Brill (in Bucks), or is it Brigg, or perhaps Bridport, or somewhere thereabouts.
