ScratchCard Pro: Ultimate Guide to Setup and Customization

Introduction

ScratchCard Pro is a modern, flexible scratch-off component designed for web and mobile applications, enabling engaging reward mechanics, promotions, and interactive experiences. This guide walks you through installation, core setup, customization options, integration patterns, analytics, security considerations, and practical tips to get the most out of ScratchCard Pro.

1. Installation and Initial Setup

- Requirements: Modern browser or WebView, Node.js (for build pipelines), and a server-side API (optional for validation/fulfillment).

- Install via npm/yarn:

- npm: npm install scratchcard-pro

- yarn: yarn add scratchcard-pro

- CDN: Include the compiled JS and CSS files if you prefer a CDN or static import.

- Basic initialization (vanilla JavaScript):

- HTML: create a container

- JS:

const scratch = new ScratchCardPro({

container: '#scratch-root',

width: 320,

height: 200,

rewardContent: '

coverPattern: 'silver',

onReveal: (result) => { console.log('revealed', result); }

});

scratch.mount();

2. Core Concepts and Options

- container: CSS selector or DOM node to mount the card.

- size: width and height in pixels or responsive units.

- rewardContent: HTML or component shown after reveal.

- coverPattern: prebuilt patterns (silver, gold, gradient) or custom image.

- brushSize: size of the scratch brush/touch area.

- revealThreshold: percentage of area scratched to auto-reveal.

- durability: number of interactions required; useful for gamified reveals.

- animations: entry/exit animations for the reward content.

- callbacks: onStart, onProgress, onReveal, onComplete for lifecycle control.

3. Visual Customization

- Cover styling:

- Use built-in patterns for quick setup.

- For custom imagery, provide coverImage: 'url(...)' and set blend modes if supported.

- Reward styling:

- The rewardContent accepts HTML so you can insert buttons, images, or micro-interactions.

- Style via CSS or pass a component reference for framework integrations (React/Vue).

- Theming:

- Expose a theme object: colors, borderRadius, font, shadow.

- Example:

theme: {

primary: '#FF5A5F',

background: '#fff',

borderRadius: 12,

shadow: '0 4px 14px rgba(0,0,0,0.08)'

}

- Fonts and localization:

- Load custom fonts using standard @font-face or external loaders.

- Ensure reward text is localized and supports RTL if needed.

4. Behavior Customization

- Brush behavior:

- brushSize: adjust for desktop vs mobile.

- brushShape: circle or square.

- Reveal logic:

- revealThreshold: 50 means reveal when 50% scratched.

- manualReveal: disable auto-reveal to require an extra user action.

- Progressive reveals:

- Use multiple layers and thresholds to create multi-step reveals (e.g., scratch three panels to win).

- Sound and haptics:

- Hook into onProgress to play scratching sound and send haptic feedback on mobile.

5. Templates and Skins

- Prebuilt templates: promotional coupon, mystery box, multi-panel game, loyalty reward.

- Custom skins:

- Combine cover patterns, animations, and reward types to create unique skins.

- Save skins as JSON presets for reuse:

{

"name": "Holiday Gold",

"theme": { "primary":"#DAA520", ... },

"coverPattern":"gold",

"animation":"sparkle"

}

6. Framework Integrations

- React:

- Provide component wrapper.

- Use useEffect to mount and cleanup.

- Vue/Angular:

- Use directives/components to mount and manage lifecycle.

- Server-side rendering:

- Mount only on client-side hydration to avoid canvas issues.

7. Backend Integration and Fulfillment

- Prevent client-side forgery: never finalize prizes purely on the client.

- Flow recommendation:

- User interacts with the scratch card client-side.

- When reveal occurs, client sends a reveal request to server with a nonce/session id.

- Server validates eligibility (user, inventory, rate limits) and returns a signed token or redemption code.

- Client displays the server-approved reward and records analytics.

- Concurrency: use atomic operations or database transactions for limited inventory or one-time rewards.

8. Analytics, A/B Testing, and Metrics

- Track events: impression, start-scratch, progress (percent), reveal-start, reveal-complete, claim.

- Use UTM and session identifiers to link behavior to campaigns.

- A/B testing:

- Vary cover patterns, revealThreshold, and reward values to measure conversion lift.

- Example metrics: scratch-to-reveal rate, claim conversion, time-to-reveal, revenue per impression.

9. Accessibility and Localization

- Keyboard interaction: provide keyboard shortcuts to reveal content for users who can’t use pointer events.

- ARIA: ensure the reward content is announced upon reveal (aria-live).

- High-contrast modes: ensure cover and reward colors meet contrast guidelines.

- Localize text and images; account for text length in different languages.

10. Security and Anti-Fraud

- Avoid embedding prize logic or inventory counts client-side.

- Use signed tokens (HMAC/JWT) when returning redemption codes.

- Rate limiting: throttle reveals per user/IP to prevent abuse.

- Tamper detection: include server-side verification of scratch events or use cryptographic challenge-response when starting a scratch session.

11. Performance Optimization

- Use canvas-based rendering with requestAnimationFrame for smooth scratch interactions.

- Lazy-load assets (cover images, sounds) to reduce initial payload.

- Debounce progress reporting to the server to minimize network chatter.

- Use device pixel ratio scaling for crisp rendering on high-DPI screens.

12. Troubleshooting and Tips

- Scratch not responding on mobile:

- Ensure passive event listeners and touch handlers are correctly registered.

- Prevent default scrolling in the scratch area while touching.

- Reveal never triggers:

- Check revealThreshold and ensure brush/touch events are being counted correctly.

- Blurry visuals:

- Scale canvas by devicePixelRatio and redraw to match actual pixels.

- Testing:

- Use deterministic seeds and unit tests for the reveal logic.

- Test across browsers and WebView versions commonly used by your audience.

13. Example Configuration (JSON)

{

"container": "#scratch-root",

"width": 360,

"height": 200,

"coverPattern": "silver",

"coverImage": null,

"brushSize": 26,

"revealThreshold": 60,

"manualReveal": false,

"theme": { "primary": "#1E90FF", "borderRadius": 10 },
