Real single-player Texas Hold'em against AI — no accounts, no real money,
open source and provably fair.
▶ Play at playpip.io · no signup, nothing to install
Free poker apps tend to look and feel like a scam: neon, leather textures, coin jingles, and more time spent closing offers than playing cards. Pip is the opposite — a flat, calm, black-first table where the poker is the whole product. Single-player, play money only, no pop-ups, no fake felt.
- The venue ladder — ten winner-take-all sit-and-go tournaments, from the 100-chip Friends' Garage to the 1,000,000-chip Main Event. The buy-in is your starting stack; win the table, take the prize, climb. Blinds escalate, so tournaments always end. Side tables (turbo, deep, heads-up, bounty) twist the format without gating the climb.
- The cast — opponents are a fixed troupe of regulars with faces, bios, and personalities, not random bots. Doris plays every hand; Frank bluffs constantly; the Vault has a boss. Your reads on them build across sessions, and they occasionally say something dry.
- The Daily Deal — one date-seeded tournament a day: everyone in the world plays the identical shuffle, provably (the engine is open and deterministic). Once a day, no streaks, a calm copyable result line.
- Hand permalinks — share any hand as a URL; the whole hand is encoded in the link (no server, no account) and replays step-by-step for whoever opens it.
- The Chip Shop — spend winnings on card backs, a four-colour deck, table finishes, and souvenir chips of venues you've conquered. Style, never edge: nothing for sale affects gameplay, and award chips can't be bought.
- Broke? Win your way back — there's no free top-up. The Kitchen Table freeroll opens when you can't afford the Garage: beat one soft opponent heads-up and the winner's stake buys you back onto the ladder.
- Ambient help — live win-% equity, hand strength, plain-English reads on opponents, and a reviewable last-hand history. Informative, never nagging.
- Yours, locally — your profile, Roll (bankroll), rank, collection, and style live in localStorage (versioned, exportable). No login, no server, no account. The only analytics are anonymous and cookieless — see Privacy below.
- Light and dark themes, quiet tactile sound, desktop and mobile layouts.
Play money only: balances are chips, never a currency. The only shop takes chips you won at the table — nothing costs real money, ever.

A change is done when pnpm test:all passes (and build for structural
work). The UI isn't unit-tested — verify it by running the app.
Three layers with hard boundaries (Next.js App Router, React 19, Tailwind v4, Zustand, Framer Motion):
- Engine —
src/lib/poker/. Pure, deterministic, React-free Texas Hold'em: dealing, betting, side pots, hand evaluation, Monte-Carlo equity, and the AI policy. Every rule lives here, and ships with tests. - Orchestration —
src/store/.game.tsruns the tournament over time (turn pacing, AI timers, blind escalation, hand history, the economy);profile.tsis the persisted player (versioned, with migrations). - Presentation —
src/components/,src/app/. Reads the stores; look & feel only.

No accounts, no cookies, no personal data. Your profile lives in your browser, not on a server. The only thing Pip records is anonymous, cookieless usage counts (via Umami) — no fingerprinting, no ad tech, nothing tied to you. The privacy page lists exactly what's counted and for how long. Because the whole app is open source, you can verify all of this in the code.
Contributions are welcome — and not only code. Playtesting and bug reports, design and
UX feedback, docs, and spreading the word all count. Start with
CONTRIBUTING.md, see what's next in ROADMAP.md, or pick
up a good first issue.
Pip is built by playpip, open source, and under
active development. It's a pure front-end app: no backend and no accounts —
everything runs in the browser and persists locally. The engine is deterministic
and fully unit-tested, so anyone can read exactly how a hand is dealt and shuffled —
provably fair by inspection, not by promise. The product docs in docs/
are the source of truth for everything from the brand to the
economy.
Openness is a deliberate foundation: as Pip grows to include things you can pay for (cosmetics and extras — never pay-to-win) and social/multiplayer play, a public codebase is what keeps the anti-scam promise honest. Contributions welcome.
Play money only, forever — chips are never a currency, and nothing is for sale.
