About moggles
moggles is a free head-to-head photo rating game. You’re shown two photos at a time and pick your favorite. Every pick adjusts both photos’ ratings ELO-style — the same math that ranks chess players — so a photo that keeps winning climbs and one that keeps losing drifts down. The highest-rated rise to the top of a live leaderboard.
How it works
- You’re shown two photos side by side.
- Tap the one you like more — no sign-up needed to vote.
- Both ratings update instantly, ELO-style.
- Submit your own photo to enter the ring and climb the leaderboard.
Frequently asked questions
What is moggles?
moggles is a free head-to-head photo rating game. You're shown two photos and pick your favorite; every vote adjusts each photo's rating, and the highest-rated climb a live leaderboard.
How does the rating work?
Every photo has an ELO rating — the same system used to rank chess players. When you pick one photo over another, the winner gains points and the loser drops. Beating a higher-rated photo earns a bigger jump than beating a lower-rated one.
Do I need an account to vote?
No. Anyone can vote without signing up. You only need an account to submit your own photo and appear on the leaderboard.
How do I get on the leaderboard?
Sign up and submit a photo. It enters the ring at a starting rating and moves up or down as people vote. Leaderboards are ranked by ELO and split by category.
Is moggles free?
Yes — voting, submitting your photo, and climbing the leaderboard are all free, and there are no ads. A few optional paid extras may come later, but nothing you ever need to pay for to play.
Can I remove my photo?
Yes. You can replace or remove your photo, or delete your account entirely, at any time from your settings.
