Finger Grinder is a reflex game for your Windows Phone that if you're too slow your finger tips could be toast. Well...in a virtual sense of things.
Not sure when all these finger smashing games snuck into the Marketplace but Finger Grinder is a well animated, reflex challenging game from this genre. You have three devices to try to avoid with either one or two fingers.
From Finger Grinder's main menu you have options to play the game, view the local leaderboards, access the options (volume/vibration on or off) and the developer's about screen. Once you start the game you have to choose your poison.
