One snippet, full control
Drop a JS loader or sandboxed iframe into any web app, pick the project token, and decide where campaigns appear. The widget stays a thin client — your backend stays the source of truth.
B2B retention infrastructure
One script. Game loops that keep bringing users back.
Branded mini-games, streaks and promo campaigns you embed in an afternoon. Progression, caps and fraud checks run on our servers; the reward decision reaches your backend as a signed webhook.

Product shape
A retention engine you can embed in a weekend.
Not a badge widget. A compact retention engine for SaaS, e-commerce and communities that need measurable return visits — with anti-fraud, Stripe billing and a React admin included.
Quest & streak logic
Daily quests, XP, streaks, leaderboards and completion rules — server-authoritative, no game infra to own.
Signed reward callbacks
HMAC-signed webhooks for coupons, points, unlocks, CRM events or email triggers — with idempotency keys.
Brand skins
Change colors, copy and campaign visuals so the widget feels native in every client product.
Analytics surface
Plays, completions, reward unlocks and return behavior — by campaign and segment.
Anti-fraud built in
Rate limits, session fingerprints, a server-side FraudGate and signed events keep rewards from being farmed.
Visible product, backend-first engine
The dashboard stays visual. The engine stays reliable.
What your team touches is a focused retention widget — campaigns, skins, webhooks and a compact dashboard. What keeps it honest is a Rust backend that stays authoritative about every play, cap and reward.
- Embed, campaign builder, reward webhooks and dashboard metrics in one product.
- Progression, caps and fraud rules run on our servers; identity and fulfillment stay on yours.
- Ships with a React admin, JS / PHP / Python SDKs and a full API reference.
Interactive demo
Switch the same engine between game modes.
One shared progression layer sits behind every mode. Moving a campaign from a streak to a quiz is a change of configuration, not a second integration.
Daily Match Quest
A branded match-3 challenge that turns one session into the next return visit.

Not vaporware
What's already shipped.
RetentionPlay is a working vertical slice, not a pitch deck. The retention engine, admin and integrations are already implemented and tested.
Authoritative Rust core
Modular monolith: unified /v1/events ingress, SpecEngine, ProgressionService with hot/cold state (Dragonfly + Postgres) and graceful degradation.
7 game adapters
Streak, quiz, scratch, clicker, match-3, memory pairs and wheel — driven by a data-first GameplaySpec, served through one generic play shell.
FraudGate & rewards
Server-side fraud rules, caps and cooldowns, score reconciliation, atomic idempotency and HMAC-signed reward webhooks with replay protection.
Admin, SDKs & docs
React admin, JS / PHP / Python SDKs, WordPress & Shopify integrations, Swagger API reference and a full docs site — deployable via Docker Swarm.

FAQ
Questions teams ask first.
Built developer-first: you stay in control of identity, rewards and data. Here is how the boundaries work.
Where does reward logic actually run?
On the backend. The widget never decides rewards. Eligibility, caps, cooldowns and fraud checks are evaluated server-side, then a signed webhook tells your system to grant the reward.
How do you stop reward farming?
Rate limits, session fingerprints, score reconciliation and a configurable FraudGate. Reward-bearing outcomes can be required to come from your backend via a server API key.
How fast is integration?
Anonymous free-play is one snippet. A production identity or reward loop asks your backend to call /v1/server/session-token with a session:issue API key, then adds the returned session token to the widget.
Can I match my brand?
Yes. Colors, copy and campaign visuals are configurable per project, and the widget renders in a sandboxed iframe so it stays isolated from your app.
What about my data and auth?
You keep identity and billing. RetentionPlay uses scoped project/session tokens; secrets never live in the browser, and admin/reward actions are audit-logged.
What happens if RetentionPlay is down?
The widget lives in a sandboxed iframe, so a failure stays inside it and never blocks your page. On the backend, progression degrades from the hot store to Postgres instead of dropping the session, and webhook delivery retries with idempotency keys.
Which games are available?
Seven adapters today — streak, quiz, scratch, clicker, match-3, memory pairs and wheel — all driven by the same progression layer, so new surfaces reuse it.
Can I prove it moved retention?
A/B exposure assigns each user a stable cohort and the dashboard reports D1 and D7 return per arm, so the comparison is against a held-out control rather than against last month.
