Quick check: you're human
Jump over three obstacles. No time limit, unlimited attempts.
“Slow” lets the obstacles approach more gently; “High contrast” draws them with a pattern instead of colour. Esc pauses at any time.

Automated programs call this page in bulk. A short interaction that is easy for people and costly for scripts holds those requests back, without an account and without deciphering images.
Your figure runs in from the left. Space, Enter, a click or a tap makes it jump. Clear three obstacles in a row and the check is passed. If you touch one, counting starts over, as often as you like and with no penalty.
There is no time limit. Esc pauses at any point, and the game pauses automatically when you switch to another tab.
“High contrast” draws obstacles with a pattern and heavy outline instead of colour. If jumping is not an option, verify via “Verify by e-mail”. The link unlocks access without the game.
Only whether your jumps succeeded is measured. No profiles, no permanent storage, no sharing with third parties.
