🎉 So you've won a game, congratulations!
Proof Of Treasure Coin is a Chia Asset Token, running on the Chia blockchain, so in order to receive your coins, you just need a wallet capable of receiving Chia Asset Tokens (CATs). Once you have your receive address from a compatible wallet, you can submit that on your unique win page and your tokens should be with you fairly quickly depending on network congestion.
If you don't already have a wallet, you might want to consider some of these wallets to store your coins:
Pawket App: (Pawket is an open-source wallet for the chia ecosystem, optimised for both mobile and desktop)
GOBY Wallet: (Goby is an open-source browser plugin wallet for the Chia Network)
In order for your wallet to recognise the coins, you'll need to add the CAT asset ID to your wallet:
