Gin rummy variants
The basic game is the same in all three: 10 cards each, draw and discard, sets and runs. What changes is when you may end a hand and how it is scored. Each variant can be played here against the computer.
Oklahoma gin
The first up card sets the knock limit. A spade up card doubles the hand. Usually to 150.

No knocking. A hand ends only with gin, or a draw when the stock runs out.
