The idea
What is 12th Man?
Every team has eleven players. The twelfth is the crowd, and that's you. This is where World Cup fans back their team, cheer, and call the scores. Everything you do here is saved permanently, so your support and your predictions are provable, forever.
What can I do here?
Get your Fan Card
Pick one team, one time. It's your permanent supporter badge, proof of who you backed and since when.
Pick your team →Post chants
Your chants hit the live wall for the whole world to see, and they never disappear.
See the wall →Call scores before kickoff
Locked at kickoff, no take-backs. Nail the exact score: 3 pts. Right result: 1 pt. Points land automatically after full time.
See the fixtures →Climb the leaderboard
Every point and every chant counts toward your team's fanbase total. Loudest country wins.

Cheer and call scores
Post chants, predict results before kickoff, climb the world table. Exact score: 3 pts. Right result: 1 pt.
Why "saved forever"? What's underneath?
Every action here (a chant, a prediction, your Fan Card) is a tiny record on Solana, a public network that nobody controls alone. That's why nobody, including us, can edit it, fake it, or delete it. And it's why using it costs a fraction of a cent. That's the entire reason this isn't just another website: your bragging rights don't depend on trusting us.
Does it cost real money? No. Right now it runs on Solana's test network, so everything is play money. Try it below.
Try it yourself
What you need
The Phantom (or Solflare) browser extension, and about 2 minutes.
Flip Phantom into play-money mode
In Phantom: Settings → Developer Settings → Testnet Mode ON. That switches it to Solana's practice network (devnet). Nothing here costs real money.
Grab a ready-made test account
Both accounts below are loaded with 1.5 devnet SOL. Import one in Phantom: Add / Connect Wallet → Import Recovery Phrase.

One team per account, forever. If the account already has a Fan Card, that step is done for you; everything else still works. There are two accounts so a second tester can pick a rival team.
Or use your own wallet
Already have one? Switch it to devnet and grab free practice SOL from faucet.solana.com.
