Where's the captcha at registration that only I don't see?

Hey lightenx you need to refresh your page. After reloading your page captcha will be shown. Hope it works for you.

I got this also sometimes with the login. Refreshing the page would do the trick. If it doesn't restart the browser.

Looks like a nice game. Will try it now.
