This casino slot machine was used for a Zipcar advertising campaign in London. A bike messenger was equipped with a mobile touchscreen backpack that ran this game. He was randomly stop people on the street and ask them to play the game.
The kiosk was written in Adobe Flash and built to run fullscreen on a touch screen display.
The mechanics of this were difficult as there was a car given away as a grand prize. The prize distributions for the tumblers are the same as used in casinos.
