Players lay tiles beginning at the Sheriff’s Office, and must find dynamite at the Survey Camp and get to the mine and blow it up before noon. While you’re doing this, there are bandits around that will try and stop you. Western in my Pocket features a modular board, so no 2 games are ever the same.
