Purchase a game

Step 02
Copy your embed code
Your dashboard shows a two-line snippet: a script tag and a div with your unique site key.
Step 03
Paste into your form
Drop it into any HTML form. When a visitor passes the game, a token is generated. Verify it server-side before processing the submission.

The checkbox is dead.
Security doesn't have to be annoying. Here's why developers are switching.
Bots can't play games
Game logic requires real-time human input: spatial reasoning, reaction time, decision making. No scraper, headless browser, or ML model beats it without your token system catching it.
Users actually enjoy it
Instead of squinting at blurry letters or clicking fire hydrants, visitors play a 10-second arcade game. Conversion rates go up. Bounce rates go down. People screenshot it.
Two lines to embed
One script tag. One div. Drop it anywhere: React, Vue, plain HTML, WordPress. No SDK, no npm package, no bundler required.
Server-side token verification
Game completion generates a signed short-lived JWT. Verify it on your server before processing any form submission. Bots can't fake the token.
Pay what you want, keep forever
No monthly fees. No per-verification charges. No usage limits. Pay once, embed everywhere, use indefinitely.
Your brand, not Google's
No reCAPTCHA watermark. No Google tracking. No privacy policy footnotes about third-party data collection. Your form, your experience.
