Cutthroat Pinochle Lite gives you a taste of the full-featured Cutthroat Pinochle app also available in the Mac App Store. The lite version plays individual hands only rather than a full game, and does not record game stats. There is a link in the app menu to the full version in the Mac App Store.

Cutthroat Pinochle is a 3-handed card game with a special 48-card deck of 9s, 10s, jacks, queens, kings and aces. The game consists of a repeating sequence of bidding (for the right to take the optional kitty and name trump), melding, and trick-taking. Players score points by melding various card combinations and by taking tricks. Adjust the rules to play the game you’re familiar with.
