Not a video course. A poker trainer that teaches back.
Poker is learnt by making decisions, not by watching them. Here every decision gets feedback.
Every decision is explained
A wrong answer comes with the exact reason: pot odds, ranges or position. Mistakes return at the end of the lesson until you understand them.
An Academy that plays like a game
18 lessons as short interactive cards instead of long text, a path map with stars, and module exams with lives. A friendly way to learn how to play poker from scratch.
Maths you can verify
Outs, pot odds, equity, EV, SPR, MDF and ICM are computed by the same engine in lessons, trainers and calculators.
Progress you can see
Accuracy by day, week and month, a leak radar and ranks that keep you coming back, synced across devices.
Nothing to install
Runs in the browser on a phone or a computer. Chips are virtual and no card is needed to start.
Calculators and ranges, free for everyone.
No sign-up and no payment: pot odds calculator, equity calculator, ICM calculator, MDF, SPR, fold equity, hand combinatorics, risk of ruin, hand rankings and 6-max and 9-max preflop charts.
Preflop charts: 6-max and 9-max
Interactive 13×13 matrix with opening ranges for every position, 3-bets and big blind defense at 100bb.
Poker calculators
PokerStars and GGPoker hand review: find your mistakes in a minute.
Upload a hand history from PokerStars or GGPoker and get every decision reviewed street by street: preflop against ranges, postflop by equity and pot odds. Files are processed in your browser and never uploaded.
- Export your hand history from the PokerStars or GGPoker client (a .txt file).
- Drop the file into the trainer: cash and tournament NLHE 6-max and 9-max are supported (antes included, Nash push/fold on short stacks), many hands at once.
- Get mistakes by street, your costliest hands and a leak report by position.
Beta: the review is approximate and is not a solver. 5 hands a day are free, no limit with PRO.
