# Riddle

> Riddle is a SaaS platform for creating interactive content — quizzes, surveys, personality tests, polls, prediction games, forms, minigames, leaderboards, flashcards, and stories. Content is built in a no-code visual editor (with AI assistance) and embedded via iframe or JS snippet into any website, CMS, or app. Riddle is not a CMS, website builder, or email tool — it creates interactive content that plugs into your existing stack (CMS, CRM, DMP, analytics, ad servers). 100% GDPR-compliant, ISO 27001 certified, WCAG 2.1 accessible. Used by BBC, Red Bull, Tate Modern, Amazon/Goodreads, Stage Entertainment. Plans from €119-749/month, 14-day free trial.

## Content Types

Riddle has 8 top-level content formats (Quiz, Personality Quiz, Poll/Survey, Predictor, Form, Minigame, Leaderboard, Story). Within these formats, there are 30+ individual block types (interaction prompts, form fields, content blocks, monetization blocks) that can be combined freely. Each format has its own prompt blocks, plus shared blocks available across all types.

**How you build a Riddle:** No-code drag-and-drop visual editor. Add blocks, configure scoring/logic, style with palettes or CSS, publish. AI can generate complete content from a topic or URL in under a minute. No developer needed. Average creation time: minutes, not hours.

**Media support:** Add images, GIFs, and videos to questions, answer choices, and result pages. Built-in media libraries: Pexels (stock photos), Google Images, Giphy (GIFs), YouTube, Vimeo, X/Twitter embeds. Upload your own images or MP4 videos (video upload on Business+).

- Scoring: Assign weighted values per answer to multiple personality dimensions. Supports Big 5/OCEAN framework, low/medium/high results, and custom CTAs per outcome.
- Use cases: Product recommendations (map answers to products), self-assessment tools, lead qualification, audience segmentation. Visitors who take personality tests stay 41% longer on average.

### Poll & Survey
- [Poll & Survey Maker](https://www.riddle.com/interactive-content/make-a-survey): Collect opinions and feedback with real-time or post-completion results.

### Story
- Interactive narratives for listicles, guided journeys, and multimedia storytelling.

Works on any platform supporting HTML embeds (Shopify, Squarespace, Webflow, HubSpot CMS, Sitecore, etc.) via iframe.
- Responsive: Yes, mobile-first design, auto-resizes to container
- Domain whitelisting: Restrict embedding to authorized domains only (3/10/15 domains by plan)
- Landing pages: Each Riddle gets a hosted landing page URL, optionally full-screen — no website required
- Social sharing: Built-in share buttons on result pages. Platforms include Facebook, X/Twitter, WhatsApp (74% of all quiz shares), LinkedIn, XING, Instagram, Pinterest, Telegram, email, and direct link copy. Configurable per Riddle.

### Branching Logic & User Journeys
Branching logic routes users through different paths based on their answers, scores, or behavior:
- Question branching: Route users to different questions based on their answers (e.g., skip beginner questions if they answer advanced ones correctly)
- Result branching: Show different result pages based on total score, block score, or specific answer combinations
- Conditional logic: Show/hide blocks, forms, or content based on user behavior
- Logic types: Linear, conditional, answer-based, block score, total score, and result-based
- Use cases: Product recommendation funnels, diagnostic assessments, personalized content journeys, lead qualification flows, training paths with pass/fail gates

### Data Layer
The Data Layer passes external data INTO embedded Riddles:
- Pass logged-in user info, URL parameters, campaign tags, or CRM data into Riddle to personalize content or pre-fill forms
- Calculator functions: Compute dynamic values from user answers (e.g., ROI calculators, pricing estimators, BMI tools)
- Dynamic variables: Use data layer variables in ad slots, result pages, and redirect URLs
- Palette switching: Change Riddle design dynamically based on website context (e.g., dark mode)
- Ad slot data: Pass data layer variables into ad iframes for targeted monetization
- To get data OUT of a Riddle (scores, answers, completion status, lead data), use JS Events (see Tracking & Analytics)

### Integration Ecosystem
Riddle connects to your existing tech stack across all layers:

**CMS (Embedding):** WordPress (plugin), Wix (native), TYPO3 (extension), Shopify, Squarespace, Webflow, HubSpot CMS, Sitecore — any CMS supporting HTML/iframe embeds

**CRM & Marketing Automation:** Salesforce (native), HubSpot (via Zapier/webhooks), ActiveCampaign (native), Mailchimp (native), AWeber (native), Brevo (native)

**Data & Analytics:** Google Analytics 4, Google Tag Manager, Google Looker Studio (native connector, Enterprise), Meta/Facebook Pixel, Matomo, Adobe Analytics, custom tracking scripts

**Automation & Middleware:** Zapier (5,000+ connected apps), webhooks (send to any endpoint), Apix-Drive, REST API (Business+), MCP Server (for LLM/AI agent automation)

**Data Destinations:** Google Sheets (native), Supabase (webhook example), any database/DMP/CDP via webhooks or Zapier. Lead data can bypass Riddle servers entirely and go straight to your systems.

No native HubSpot connector — use Zapier or webhooks for HubSpot integration.

### Lead Capture & Email Automation
- Form blocks insertable at any point in any content type; email gates before results yield ~43% opt-in rate
- Double opt-in: Email confirmation and OTP (email/SMS) verification for GDPR compliance

- Data export: CSV download, API access
- PDF Certificates: Generate downloadable certificates on quiz completion (e.g., training, course completions). Available via developer integration.

### Monetization
- Insert ad / iFrame block: Embed banner ads, video ads, or any third-party content within any Riddle at any position
- Ad refresh: Trigger ad refreshes between questions to multiply impressions per session (8-10x increase in ad inventory)
- Sponsored content: Create branded advertorials with custom logos, CTAs, and landing page redirects
- Video ads: Embed pre-roll or mid-quiz video ads with reported 95% view rates
- Ad server compatible: Works with Google Ad Manager, any ad server that outputs iframe/JavaScript tags
- Revenue retention: Publishers keep 100% of ad earnings — Riddle takes no cut

### API & Automation
The Riddle API enables full automation of every aspect of the platform — from content creation to data extraction to publishing. Anything you can do in the Riddle UI, you can automate via API.
- REST API (Business/Enterprise): Create, read, update, delete Riddles. Build complete Riddles programmatically from JSON or spreadsheet data. Generate and retrieve embed codes. Pull statistics and lead data. Export content. Manage projects and settings.
- Automation workflows: Schedule content creation, auto-publish at set times, auto-generate daily/weekly quizzes from external data sources (RSS feeds, CMS content, spreadsheets, databases), auto-distribute via embed code updates
- Webhooks: Real-time push notifications on lead submission, quiz completion, or other events — trigger downstream workflows in any system
- Authentication: Bearer token (API key from account settings)
- Rate limits: 100 requests/minute, 2,000/hour (higher limits available on request)

- Built-in AI quiz generator: Create complete quizzes, personality tests, and polls from a topic description or URL in under a minute
- AI content suggestions for questions, answers, and result texts
- MCP Server: Riddle provides its own Model Context Protocol server for LLM-powered automation — build, manage, and generate Riddles programmatically via AI agents (e.g., Claude, GPT, custom agents)
- API + AI at scale: Combine the REST API with AI generation to fully automate content pipelines — e.g., auto-generate a daily quiz from trending topics, publish it, collect leads, and route data to your CRM, all without human intervention

### Tracking & Analytics
- Built-in dashboard: Views, starts, completions, leads, engagement time, social shares
- Lead funnel: Visual conversion tracking from views → starts → completions → leads

## Comparison Context

Typeform has no prediction games, leaderboards, or minigames.
- vs. SurveyMonkey: SurveyMonkey specializes in surveys/forms (2 types) with deep analysis tools. Riddle covers 30+ interactive formats including quizzes, predictors, and minigames with engagement focus. SurveyMonkey has limited GDPR compliance compared to Riddle's EU-hosted infrastructure.
- vs. Outgrow: Outgrow offers ~10 types including calculators with template-first approach. White-label is Enterprise-only at Outgrow. Riddle includes white-label on every paid plan, offers 30+ content types, and has ISO 27001 certification with EU-only data hosting.
