Review each hand
street by street once it ends.

See the result and the ranges first. Then your coach explains each decision you made, in the order you played it. Ask about any choice you're unsure of in your own words, and try it again in the next hand.

Sample hand · review example

Why did you call BTN's 1/3 pot bet?

BB vs BTN Starting stacks 40BB each

Your position

BB BTN

BB hole cards

Flop

  1. Preflop

    BTN opens 2.5BBBB calls

  2. Flop

    BB checksBTN bets about 1/3 potBB calls

  1. GTO analysis

    Calling keeps the weak Qx and bluff candidates in the range and carries the pot to the next street. Raising can fold these candidates out, but if called, strong hands such as overpairs and sets can remain.

  2. Opponent range

    On Q♣8♦3♠, BTN bet about 1/3 pot after BB checked. Even at this small size, BTN's range can include strong candidates like AA, KK, QQ, 88, and 33, along with weak Qx such as KQ and QJ, and missed Ax. Separating which hands call a raise and which fold shows you the difference between calling and raising.

Next practice

Play the same board again with a different opponent. Face one who bets small often and one who bets only with strong hands, and choose between calling and raising again.

You can also play

Frequently asked questions

For any other questions, email js@lysners.com.

I'm new to poker. Where should I start?

If you're new to poker, start with First steps in poker. If you've played before, start with the level test. The level test asks you to play 16 hands without coach feedback, then gives you an overall assessment and recommends the next course.

How is the curriculum organized?

It runs from First steps in poker through preflop, short stacks, flop, turn and river, 3-bet pots, ICM and final tables, heads-up, and live tournament play, across 11 chapters and 53 courses. Each course pairs a short concept lesson with 4–30 hands of practice. No course is locked, so you can start wherever you need.

Do I play right after the concept lesson?

Yes. After you read the concept one screen at a time and answer the check questions, you move on to practice, where you play the same decision in real hands against AI opponents. If you already know the concept, you can go straight to practice.

How does review work?

When a hand ends, we first show every card and the result. Your coach then walks through the streets where you made decisions, in the order you played them. If you have questions, you can ask in your own words.

Can I pick up where I left off?

Yes. Practice in progress can be resumed from the same hand on the home and study screens.

What do the AI opponents and coach do?

Each opponent has its own playing style, such as unknown, loose-aggressive, or tight-aggressive. You tell them apart by position and style labels, and they play poker actions and make short table remarks. The coach tells you what to watch for when a hand starts and reviews the hand with you when it ends. Both are AI and can be wrong.

Can I bet real money or win money?

The chips at the table are a simulation for practicing poker decisions. We do not offer any game where you bet real money or win prizes, and there is no way to cash out chips.

How do I use credits?

Credits are spent 1 at a time when you play against the AI, ask the coach a question or read a blind structure photo. Accounts with no purchased credits or pass get 20 free uses every day, refilled at 0:00 Korea time. Unused free uses don't carry over to the next day. The beginner stage 0 course and your first level test don't use credits. Coupon credits can be used for 30 days from the day you receive them.

Can I use it on my phone?

Yes. You play in your browser with no install, and on a phone you can use concept lessons, practice, and review in the same flow.

Is it available now?

Yes. Sign in with a Google account or email and you can start right away. There is a one-time age verification step the first time you sign in.
