Without simple math, you’re playing a guessing game.

"Hands down the most well thought out and put together introduction to poker math for any skill level on the internet. I lucked out and got this on a flash sale, but even halfway through the course I’d still pay full price."

- Trevor H.

"Topics such as pot odds, hand equity, and EV were clearly defined with easy-to-understand examples. The lectures averaged about 10 minutes, which made it easy to plan and study."

The “KISS” Teaching Approach

This course follows the Keep It Simple Student (KISS) methodology. We teach progressively—from the basics to more advanced concepts—so you can implement essential poker math quickly and painlessly.

If you can do basic arithmetic, you can use the math in this course to make clearer decisions, avoid common mistakes, and stop guessing in the spots that cost most players money.

KISS teaching approach


"For anybody who doesn’t know the math of poker, it’s like you’re simply guessing. After watching this course, I realized I was playing with both hands tied behind my back. I’m itching to do more of Alton’s courses—top course!"

- Keith H.

"This is the best resource on the net for poker math. Most poker courses just glaze over the math. One thing that would be helpful is showing more how to apply it in a live game environment—doing the drills off the table is valuable, but bridging it to real-time decisions would be amazing."

- Greg P.
