CAPTCHA, but fun.
Replace image puzzles with Tetris. Verify humans through gameplay — deterministically validated server-side.

Game-based verification
Users play a quick round of Tetris instead of clicking on fire hydrants. Better UX, same security.
[#=]
Deterministic replay
Server generates a seeded piece sequence. Moves are replayed server-side to verify legitimacy — no trust in the client.

Drop-in integration
One web component on the frontend, one API call on the backend. Same siteverify pattern as reCAPTCHA and hCaptcha.
