How it works

You're shown two ad creatives. You tap the one you'd be more likely to click. Both creatives' scores move, you see where they rank, and the next pair appears. That's the whole game.

Arena CTR

Every creative carries an Arena CTR, shown as a click-through-rate percentage. It goes up when the creative wins a matchup and down when it loses. Under the hood it's a chess-style rating system — the kind where beating a strong opponent is worth more than beating a weak one — mapped onto a percentage scale so the number reads in the units marketers already think in. A strong creative sits around 5–6%, an average one around 1.1%, a weak one under 0.5%.

Arena CTR measures crowd preference inside this game. It is not a measurement of how the creative performed in a real campaign, and it should never be quoted as one. Nobody here has access to real ad-account data; the number reflects only which creative people tapped when shown the pair.

Rank

Rank is a creative's position against every other creative of the same aspect ratio. New creatives start low and climb as they prove themselves — the number shown is the rating we're confident a creative has earned, not its most optimistic estimate, so a lucky early streak can't park a newcomer at #1. A creative joins the leaderboard once it has played 20 rounds.

Matchmaking

A new creative is paired at random for its first few rounds so it meets the whole field. Once its level is roughly known, it only faces creatives rated near it, so every matchup is a genuine close call. Each pair is dealt fresh: nothing you pick carries into the next round, and refreshing the page shows you the same pair, not a new one.

No accounts

There's nothing to sign up for. There are no scores, streaks or profiles, because the point is looking at a lot of creative quickly and noticing what wins — not competing.

Where the creatives come from

The starting pool was assembled by hand and given a rough head start — sorted into good, decent and weak tiers — so the leaderboard wasn't empty on day one. That head start is deliberately small and the crowd overrides it within a handful of rounds. Beyond the starting pool, creatives arrive through submissions from people who confirm they hold the rights to them, and every submission is reviewed by a person before it plays.

No brand names or logos are attached to creatives as labels. If something in the image identifies a brand, that's the image; the site doesn't add to it. Each creative carries four craft tags — Style, Hook, People and Copy — that describe how it was made, which you can filter the leaderboard by.

Taking something down

If a creative is yours and you'd rather it weren't here, ask and it comes down. No argument.
