CryptoGammon

CryptoGammon is an on-chain backgammon game developed by Switzerland's Crypto Games AG on Concordium, announced in September 2022. Gameplay keeps classic backgammon rules and adds tournaments and global matchmaking, with a social layer supporting camera and voice chat; assets take the form of NFT boards, checkers, shakers, dice, avatars, and emojis, and players can configure their own NFTs into the game profile, while those without a connected wallet play with the standard board and accessories. The technical choice rests on Concordium's identity layer: protocol-built-in KYC and age verification let skill-based matches run in a compliant way, event prizes are denominated in CCD, and NFT trading happens on its ecosystem marketplace.

The project received a Free and Open Grant from the Concordium Foundation and was built with development partner 9HZ. A naming distinction is required: a Solana-based project of the same name issues the CBG token and supports USDC deposits and withdrawals, and is a different entity from this one.
