I've been playing a lot of minesweeper on my phone lately and it annoys me how much randomness their is to the game. I'm tempted to make a version that completely removes chance from the game so it's 100% deductive reasoning required to complete any level.

Something even more interesting is to change the unknown parts of a board loose up until the player commits a move. Thus enabling us to tweak a "luck bias" so unknown moves always results in no bomb (or even more devious: always bombs)
