Hi, We created this site after trying to learn the theory found in most Poker Math books. Rote memorization of equations didn't cut it -- so we created this interactive site instead, thinking it might be useful to others. Let us know your thoughts! Thanks P.S. The site's name is PokerGym -- the HN spam-killing bot didn't seem to like stories with "Poker" in the title. P.P.S. We use poker-eval (through its Python bindings) to dynamically generate training questions. Here's a nice intro to it on Coding the Wheel: http://www.codingthewheel.com/archives/a-pokersource-poker-eval-primer http://www.codingthewheel.com/archives/a-pokersource-poker-e...

  Congrats. It looks great. Some feedback here after doing the first demo. I expected that every lesson would contain a practical example. In the demo, it's good to know that you have 9 outs, but the real objective is knowing that you shouldn't call a bet unless the pot odds are above certain value. Otherwise, this lesson alone doesn't quite teach much. Also, even if you didn't prepare more lessons (I guess you'll wait to see if it picks up traction), I'd have liked to see some more lessons, even if marked with a "coming soon" sign.

    Thanks for the feedback. The demo linked from the home page is much more a demo of the site's "abilities" than a full course. Once you finished the demo, did you try going through a "Learning module"? (tip: you don't really have to register... simply click the PokerGym logo in the upper-left corner). There are two courses which are fully available -- Counting Outs and Combos. If you're signed in, you should see them on this page: https://www.pokergym.com/dashboard/ https://www.pokergym.com/dashboard/

Even though I know Greg I dont think I'm biased in saying that it is a pretty awesome way to get better at poker! I've completed the first two modules and learned a lot of cool tricks (like rapidly calculating your outs)!

Awesome! Great UX. It is like http://duolingo.com http://duolingo.com or http://www.memrise.com http://www.memrise.com for Poker. :)

This look sick and I LOVE your funnel - Quickly show how it works, register and then sell. Def. will check this out!

  Thank you! It seems to be working -- our conversion rate from homepage to registration is about 10% (although it's very early, and I'm basing this off a few hundred uniques). Still hoping to hit the HN homepage :-)

    I felt hornswaggled when I finished the first one and saw that the next one costed $4.99. I had just signed up too. When I clicked to try it I did so because it clearly stated "You can only get better, and it's free." However this was a flat lie. I looked for a way to delete my account but could not find one. I felt deceived. I just checked back at the site without logging in and it even says "Save your progress to unlock" for the next modules. "Save your progress" is a euphemism for "sign up" and then when you do that it doesn't actually unlock. $4.99 unlocks the module. Wow.

      Hi jrode, Sorry that the site left a bad impression on you. We were trying to get across that "it's free" applied to the fact that "trying it" (the main action) was free. We'll make this clearer. By the way, we will have more free courses (there are two which are completely free right now). It's just a matter of time. Sorry also about not having a way to delete your account -- it was an oversight, and it will be corrected. Finally, you're right that the "Save your progress to unlock" copy is, in fact, incorrect. We'll make sure to get it right. Thank you for your feedback!

        Hey, thanks. I really liked the site by the way, it is very nicely done. I also understand why you would charge for the modules, and you should. Just thought it could be more clear. Again, thanks for responding.

I’ve been waiting to learn Poker for some years. I’ve no reason to didn’t start right now with this!
- gregsadetsky 14y ago
  We'll have more beginner courses as well in the future, although the Counting Outs course (the first one) shouldn't be too hard. Let us know what you think! Thanks

I really like the tutorial style of the lessons and the smoothness of the UX. I am not a poker player but I just recommended it to a friend who plays a lot. Nice work!
