Card games, not gambling. Nothing on this shelf takes money, pays out or asks you to register, and there is no way to buy anything inside these games. What is left is the card play itself: Klondike with four free cells, Demon Solitaire, Black Widow Patience, and Stop The Bus for a hand against the computer. The smallest category in the archive, and the one with the most patience in it.
15 games, free to play in the browser.
