Roulette is a one-button game which sees you sat at a table playing a game of Russian Roulette. You and your opponent take it in turns to point the gun at your head and pull the trigger. Firing the gun is done by holding down the space bar on your turn.

The whole thing is made up of dozens of video clips strung together, with a dark graphical effect over the top. It's really shocking stuff - I found myself gritting my teeth and watching out of the corner of my eye every time the trigger was pulled. The outcome is completely random, as are the reactions from your competitor, hence each game is different.

Please heed the warning above - if you think you're not going to like this, then do not download it. Otherwise, grab it from the Select Button forums and see how shocking a one-button game can be.
