最近のrecaptchaって文字入力がないんだが、なんか微妙なルーチンなんだなぁ、、

I would assume it looks at how you behaved prior to clicking, how your cursor moved on its way to the check (organic path/acceleration), which part of the checkbox was clicked (random places, or dead on center every time), browser fingerprint, Google cookies & contents, click location history tied to your fingerprint or account if it detects one etc.
