An online scratch card is a virtual version of the classic scratch-off lottery or gift card. Instead of using a coin to scratch a physical coating, you use your mouse cursor or fingertip on a touchscreen to "scratch away" a digital layer, revealing a hidden message or prize underneath. It's perfect for virtual celebrations, email marketing campaigns, social media giveaways, and adding a fun interactive element to your website.

This tool uses HTML5 Canvas technology to simulate the scratching experience. A silver metallic coating is drawn on a canvas element that sits on top of the hidden message layer. When you drag your mouse or finger across the canvas, we use the destination-out composite operation to erase the coating at your cursor position with a soft-edged circular brush. The system periodically samples the canvas pixels to calculate scratch progress. Once you've scratched over 65% of the surface, the coating automatically fades away to fully reveal the surprise message.

Absolutely! You can either choose from our curated preset messages (covering categories like celebration, love, motivation, humor, and fortune) or type your own completely custom message in the input field. The hidden message supports emoji, and you can write up to 120 characters. Once you click "Apply," the new message will be hidden beneath a fresh scratchable coating, ready to surprise the next person.

Yes, this online scratch card tool is 100% free and requires no registration, login, or download. You can use it as many times as you want, with unlimited custom messages. There are no hidden fees, no watermark, and no data collection. It's designed to be a fun, accessible tool for personal and light commercial use.

Yes! This scratch card is fully responsive and optimized for mobile devices. It supports touch gestures (finger scratching) on smartphones and tablets running iOS or Android. The canvas automatically scales to fit your screen size, the brush size is adjusted for fingertip use, and touch-scrolling is prevented only on the card surface so you can still navigate the page normally. The entire interface — including preset buttons and custom input — is mobile-friendly.

When you scratch approximately 65% or more of the silver coating, the tool triggers an automatic reveal. The remaining coating smoothly fades away over 0.45 seconds, and a burst of colorful confetti particles celebrates the full reveal of your surprise message. You can also manually reveal the entire message by thoroughly scratching the entire surface. The progress bar above the card shows your real-time scratching percentage.

Definitely! Many businesses use virtual scratch cards for email marketing campaigns, social media contests, customer loyalty rewards, and product launch events. You can customize the message to reveal discount codes, prize notifications, or special offers. The interactive nature of scratch cards drives significantly higher engagement rates compared to static content. For advanced use, you can even take a screenshot of the revealed message or integrate similar functionality into your own website.

No. This tool operates entirely within your browser. Your custom messages, scratch progress, and usage data are never transmitted to any server, stored in any database, or shared with third parties. Everything happens locally on your device. When you close the page or reset the card, all temporary data is cleared. We respect your privacy completely.

If you experience difficulty scratching on mobile, it may be due to your browser's touch sensitivity settings or screen protector thickness. For the best experience, use a firm, steady drag motion with your fingertip rather than quick, light taps. The brush uses a soft edge for natural scratching feel. Also ensure your browser is updated — Chrome and Safari on iOS/Android both provide excellent touch support for HTML5 Canvas applications like this one.

The default brush radius is optimized for both mouse (40px) and touch (48px) interactions, providing a comfortable scratching experience. The auto-reveal threshold is set at 65% to balance the fun of manual scratching with the convenience of not needing to be perfectly thorough. While this web version doesn't expose brush size controls (to keep the interface simple), developers can easily modify these parameters in the JavaScript code — look for brushRadius and autoRevealThreshold variables.
