DOOM CAPTCHA
Play DOOM and defeat three monsters to pass a CAPTCHA. A joke with a point: it makes the cost of a challenge impossible to ignore.

What it asks
Defeat at least three monsters in a WebAssembly build of DOOM running inside a CAPTCHA-style box. The demo starts with 50 bullets and 100 health. A counter tracks progress towards the challenge.
Why it matters
It turns an interruption into a game, while making the interruption much harder to overlook. The visitor must learn the controls and finish an unrelated task before continuing. Enjoyable as an experiment does not mean suitable for a real contact or login form.
What to use instead
Let visitors complete the form they came for. CleanTalk checks submissions without a CAPTCHA puzzle. You can also compare the installable options in our CAPTCHA test.
Fun to look at. Expensive to use.
