I've secretly picked one of the 24 characters below. Ask yourself yes/no questions about hair, glasses, hats, etc., then tap a face to flip it down when you rule it out. When you're sure, click "Make Your Guess" and pick the right one.
Characters remaining: 24
Tip: click a face once to flip it face-down (ruled out). Click again to bring it back. Use "Make Your Guess" when you've narrowed it down to one.
