One Armed Bandit is a very simple slot machine simulation program. You start with 50 credits; each play costs one credit. Every time you pull the lever by pressing Space, Alt + P or selecting "Play" with your mouse, you'll have a chance to win more credits.

Unlike most slot machines, however, you only bet on the middle line in the slot machine. Any winning combinations you get on the top or bottom lines are ignored.

The credits are not saved; you lose all your earnings when you exit the game.
