Major V.3.0 update - Worldwide high-score leaderboards for each quiz and for overall odds knowledge (using OpenFeint for the leaderboards).

And in the several V.2.x updates we added more quizzes and questions, as suggested by iTunes reviews, so this app has gone to a new level since its first release.

First take our quick 10-question general assessment quiz. Then go deeper and take our pre-flop, post-flop, basic, and advanced quizzes. The quizzes cover common pre-flop and post-flop situations involving made hands and draws and random hands that you'll encounter frequently in actual play.

Then for even more of a challenge, take our hand ranges and multi-player quizzes (pre-flop and post-flop). Poker is a game of incomplete information; we can almost never put our opponents on specific cards. We have to put them on ranges of hands (e.g. "I think he has Aces or Kings or maybe AceKing") and make odds estimates based on incomplete information.

* Shows you the questions in random order, times you, and shows you the correct answers.
* Explains the players' outs and counter-outs and runner-runner outs, for post-flop questions.
* Gives you an A+ ... F grade for each quiz, and a score, and saves your grades and scores locally.
* Post your scores on worldwide leaderboards. Chat, invite friends. These social game features are optional of course.
* Built-in Outs Chart.
* Built-in Pre-Flop Odds Chart for common pre-flop matchups.
* Built-in Odds Tutorial - explains "equity", "outs", and more.

See where your odds knowledge currently stands ... See if you can improve and get all A's ... Compare your scores with friends and with players from around the world ...

There's much more to poker than just the odds of course, and you don't need to know the odds to 1% accuracy to be a good player. But you could be off far enough on your odds estimates for some situations to make a difference. We believe the odds are the foundation and are worth mastering.

See our website for more information. We're also the developers of PokerCruncher, the advanced Texas Hold'em hand ranges odds calculator, and Poker Odds Teacher, and our goal to help you master poker odds continues with this app.

Re. the slider issue in the first review (US App Store):

We can't reproduce this, and no one else has reported this. Restarting your phone after installing the app may help. Thanks to the second reviewer for feedback on this and for your review.
