Casino is a collection of four gambling games:
Backgammon
Blackjack
Fruit Machine
Roulette

All games are played in windows on the desktop and are launched from their own executables. Running one of the program also launches a application called Banker which keeps track of the player's money. To make bets money is dragged from the banker window to any of the game windows. All games use the same bank account so money earned in one can be spent in another. The game can be played by up to four players. Generous players can choose to give away money to the other players.
