Quick summary
GTO Heads-Up is a poker training tool for one-on-one play: it puts you in heads-up spots and trains you toward game-theory-optimal decisions. A focused, data-driven trainer for serious players, running right in the browser.
Who this template is for
This is a practice instrument rather than a game. It is for players who want repetitions against a baseline, not entertainment.
- Serious poker players drilling heads-up decisions who want feedback rather than a simulated opponent
- Coaches who need a shareable browser tool to put a student in a specific spot repeatedly
- Product teams looking for a reference build of a focused, data-driven training interface
What problem this template solves
Most “browser game” offerings are either heavy engine exports or toy demos that fall apart the moment you look under the hood. This build is neither.
- Engine exports ship megabytes of runtime before the first frame ever draws
- Toy demos skip the hard parts — real collision, game states, difficulty curves and persistence
- Builders who want to learn from a finished game almost never get to see the instructions that produced it
What you get with this template
You get a heads-up trainer that puts you in real spots and scores your decisions against a game-theory-optimal baseline, hand by hand.
- Modelled heads-up situations that repeat until the decision becomes automatic rather than considered
- Scoring against a GTO baseline, so abstract theory becomes a concrete right-or-wrong signal
- A focused single-purpose interface with nothing on screen that is not part of the decision
Page sections overview
| Section | Purpose |
|---|---|
| Heads-Up Spot Engine | Generate one-on-one situations that isolate a specific decision |
| GTO Baseline Scoring | Score each decision against a game-theory-optimal reference |
| Hand-by-Hand Repetition | Drill the same class of spot until the response is automatic |
| Focused Decision Interface | Strip the screen to only what the current decision requires |
| Browser-Native Delivery | Run entirely in the browser with no client to install |
Design & branding system
The design is deliberately utilitarian: a calm felt-toned surface, high-legibility numerals, and colour reserved almost entirely for feedback.
- A restrained felt-and-graphite palette that keeps the screen comfortable across long drilling sessions
- Tabular numerals and generous spacing on every value, because misreading a number is a failure of the tool
- Colour used almost exclusively to signal decision quality, so feedback is legible in peripheral vision
Mobile & speed optimization
The game targets desktop first — keyboard and mouse are the primary controls — while staying light enough to load instantly anywhere.
- No engine runtime and no asset downloads, so the whole game arrives in a handful of requests
- A capped frame delta keeps the simulation stable even when the browser tab stutters or loses focus
- The page stays lean: no frameworks, no trackers, nothing between the visitor and the game loop
How this template helps you convert
A playable game holds attention longer than any showreel. The page around it is structured to turn that attention into a next step.
- Visitors play immediately — no signup, download or install stands between them and the first round
- The finished build is fully inspectable, which turns curious players into builders who want the prompt behind it
- The one-time prompt unlock offers a concrete, low-friction next step while the session is still hot
Other information about this template
A few notes on scope before you adapt this build.
- It trains heads-up play specifically; multi-way pots are a different solver problem and are out of scope
- The baseline is a training reference for building intuition, not a live solver for a specific opponent pool
- The spot definitions and scoring thresholds are data you can retune for a different game or stake level
- It runs in any modern browser on desktop or tablet with no install
How it works
The trainer models heads-up situations and scores your decisions against a GTO baseline, turning abstract poker theory into repeatable, hand-by-hand practice.
