Version 1.24.11 of the classic Jacks or better video poker game introduces support for Mac OS X in a Universal Binary package. It is now also listed in Apple's Downloads and available from MacUpdate, Versiontracker, Download.com and Softpedia.
It's the game with 52 cards without jokers. You’ll be given 500 credits for a start and drawn 5 cards from which you can choose to hold the cards. The ones you did not hold will be replaced. In case of the win you’ll be given an option to cash out or double by guessing the rank of the next card.
Poker 1.24 is really simple but yet entertaining. Enjoy!
