No wallet needed. Press H or T to pick, space to flip. Your side locks in once you flip.

Where the 2% goes

Every flip pays a 2% fee, and all of it goes to one public buyback wallet you can check on Solscan whenever you want. That wallet market-buys $tUP every 5 minutes.

100%

Buybacks

Every lamport of the fee market-buys $tUP every 5 minutes. Every buy is on-chain.

$tUP

The house token. You don't need it to play. Holders win when the table is busy, because more flips mean bigger buybacks.

Nobody picks the side. Not even us.

On mainnet every flip settles on-chain with verifiable randomness. Here's what happens when you hit the button.

  1. You sign one transaction

    Your bet and the 2% fee go into the game's vault.

  2. An oracle rolls the number

    A VRF oracle returns a random number tied to your transaction, with a proof anyone can check.

  3. The program pays you

    Even is heads, odd is tails. Win and 2× your bet lands back in your wallet.

Questions

What are the odds?

Exactly fifty-fifty. The 2% fee is the only edge the house has.

Why is it a practice round right now?

Flips use play SOL until the game wallet is funded. Until then anyone can flip, no wallet needed.

Do I have to connect a wallet?

No. Connecting Phantom is optional. It shows your address on the table and in the live feed, and nothing else.

Will you ever ask for my seed phrase?

Never. Connecting only shares your public address. Anyone asking for your seed phrase is trying to rob you.

How big can I bet?

2 SOL per flip at launch. The cap goes up as the vault grows.

Do I need $tUP to play?

No. Anyone with SOL can flip.
