01 / Tools

One for playing, one for practising, one for the maths.

Most poker tools either deal hands at you or show you charts. These do both, and show the working.

02 / Features

The things that actually move a win rate.

Most study tools tell you what a solver would do. These tell you what your decision was worth, at your table, against the players you chose.

While you play

  • Every call and fold priced immediately. You find out what a decision was worth in big blinds before the next hand is dealt, not in a review session three days later.
  • The odds on screen if you want them. Your equity, the equity you need and what calling is worth, on a key press. Switch it off when you want an honest score.
  • A hand guide that shows what you can still make. All nine hand types with your chance of finishing with each, counted exactly on the flop and turn.
  • Rake, if you want the real numbers. Practise with the house taking its cut and see what it does to a win rate. Most players have never looked.

The opponents

  • Pick who you sit with, seat by seat. A calling station on your left and a strong regular on your right, or five maniacs. Style and skill are set separately for every player.
  • Opponents picked by percentile. Each seat is set to a standing, from the bottom 10% up to the top 0.1%. Weak players misread the board and ignore the price they are getting; strong ones do neither.
  • Save the line-ups you want to practise against. Build the table that gives you trouble and come back to it.
  • Real stakes and buy-ins. £1/£2 through £50/£100, with the buy-in range each stake actually runs.

Getting better

  • Rated on how you decided, not how you ran. Winnings over a few hundred hands are mostly luck. The rating measures the expected value you gave away, so a bad session played well still scores well.
  • A standing that moves both ways. You are shown where your play ranks, not a number only chess players understand. It climbs faster when you beat a strong table and falls when you play badly against a weak one.
  • Told which way your mistakes go. Calling too wide and folding too tight are opposite problems with opposite fixes. You get told which one you have.
  • Your own style, measured. The same labels used for the bots applied to you, from your actual VPIP and aggression factor.

Practicalities

  • Up to six tables at once. Each fully independent, with the ones waiting on you highlighted.
  • Drills for the close spots. Opening ranges and pot-odds decisions, weighted towards hands that are genuinely a decision.
  • Know when your results mean something. The variance tool tells you how many hands you need before a win rate is evidence rather than noise.
  • Nothing to install and nothing uploaded. It runs in the browser, on your machine, including on a phone.
03 / Under the hood

The maths was tested first.

A poker tool is only as good as the code deciding who wins. That part was checked against published figures before anything was built on top of it.

0.5 pts
Biggest gap across seven published preflop match-ups. Aces against kings gives 82.6% here; the published figure is 82.4%. You can check that one anywhere.
χ² = 48.3
Shuffle uniformity measured over 52,000 deals against 51 degrees of freedom. A fair shuffle scores about 51; anything under 86.7 shows no detectable bias.
0 leaks
Over 600 self-played hands with random stack sizes, no chips were created or lost. That is the test of the side-pot code.
Level
Two identical bots over 15,000 hands finish level (+5.8 ±14 bb/100), which is the check that the table itself is not biased.
04 / Methods

Named methods, not magic numbers.

Every figure here comes from one of these. They are standard techniques with standard names, so you can look up what each one does and judge for yourself whether it is the right tool.

♠ The deal

Cards are shuffled with Fisher-Yates, the only shuffle that makes every ordering equally likely, driven by the browser's cryptographic random number generator rather than Math.random. Numbers are drawn by rejection sampling, because taking a random value modulo 52 quietly favours the lower cards.

♥ Who wins

Every hand is scored by checking all 21 ways of picking five cards from seven and keeping the best one. No shortcuts and no lookup table that might be wrong in a corner case.

♦ Equity

Exact enumeration wherever it is possible: on the river every hand your opponent could hold is counted, and on the flop all 1,081 runouts are. Only where the count runs into millions does it fall back to Monte Carlo sampling, and it tells you on screen when it has.

♣ Variance and ruin

Long-run results use the central limit theorem; the chance of going broke uses the standard risk of ruin formula for a bankroll facing normally distributed swings, inverted to give the bankroll that a chosen risk requires.

Two things this deliberately is not. It is not certified or audited by anybody, and the opponents are not a GTO solver. Anyone telling you a browser tool is either of those is selling something. What is here instead is the arithmetic, in the open, with the tests that back it.

05 / Straight answers

What this is, and what it isn't.

01 Your play stays on your machine

The tools run entirely in your browser. Hands, results and ratings are worked out on your device and never sent anywhere. The account exists only to control access.

02 The equity figures are accurate

Hand strength, pot odds and expected value are worked out properly and match published figures to within half a percentage point.

03 The bots are not a solver

They follow sensible rules, and the opening charts are close to standard published ranges rather than a GTO solve. Use it to build judgement, not as a reference to memorise.

04 It is still gambling

Practise here all you like, but only play for money you can afford to lose. If it stops being a game, BeGambleAware can help.

06 / Pricing

What it will cost, when it opens.

Every plan is the same product: everything unlocked, with no limits inside any of the tools. The only difference is how you pay.
