Death Board is a Windows Phone game that has the potential to drive you nuts. It is a game that challenges you to quickly find a matching number before the game clock strikes zero.
While the game concept sounds simple, you only have a few seconds on the clock and it's surprising how long it takes to have four digit numbers register in your brain. I'm not sure how much staying power Death Board will have but for occasional gaming or as a conversation piece, the game should do well.
Available for low-memory Windows Phones, don't be shocked if your score stays in the single digits with Death Board.
