The basics
What is GTO, in one sentence?
Game Theory Optimal play is the mathematically unexploitable strategy: play it and no opponent can beat you long-term, whatever they do. We break it down fully on the “What is GTO?” page.
Do I need to be an advanced player?
No. Look up any range for free, solve any flop for free, then train it hand by hand with instant feedback. Beginners learn fundamentals; regulars close specific leaks.
Which formats are covered?
Cash games, tournaments (MTT) and Sit & Gos - from full-ring down to heads-up, deep-stacked through push/fold, each with its own solved ranges.
How the training works
How does grading work?
Preflop, your action is checked against the solver’s mixed strategy for that exact hand. Postflop, every decision is scored by its EV loss in big blinds against a deep solve.
How does the analysis screen work?
Every graded hand is saved to your account, then read back four ways: a 13×13 heatmap of your accuracy per starting hand, a ranking of your positions, your spots ordered by EV lost in big blinds, and a curve of the big blinds your training has won — measured against the rate you were giving away when the window opened, as a running total or per hand. Preflop and postflop are tracked separately, and you can view any window from the last 7 days to all time.
Free hands and Pro
How much can I play for free?
25 graded hands with no account at all, and 60 a day once you create a free account - same solver, same instant grading. They are played on chapter 1 of a real guided path: pick tournaments, cash or sit & go, and the trainer deals you opening decisions on that game's table until you have cleared 40 spots at 78%. Preflop charts are browsable for free too. Pro is what removes the daily cap and opens the six chapters above the first.
Is there a free trial?
There is no timed trial, because there is something better: the free tier does not expire. Chapter 1 of every path, 60 graded hands a day with a free account, every preflop chart and the solver stay free for as long as you want them - that is your trial, and it runs on the real trainer with the real grading. Pro is billed from day one and you can cancel it at any time, keeping access until the period you paid for ends. No real-money play is involved.
What happens if I cancel?
Cancel in one click from the customer portal. Your subscription stays active until the end of the period you have already paid for, then the account drops back to the free tier - it is not deleted, and neither is your history: every hand you have played stays in your analysis, and the free chapter keeps grading new ones.
Still deciding?
The two things worth an answer are both free and neither needs an account: play a hand and see it graded, or solve a spot of your own and read the strategy back.
