Getting started

Gaambl Lotto

Moderate (25%), Aggressive (15%), High Risk (10%), Extreme (5%)

Players & duration

10–500 players, 24h–30 days

Fees

Flow

Create/join → randomness requested → finalize → winners claim prizes

Gaambl Raafl

NFT-based raffles: players pay an entry fee for a chance to win a specific NFT (ERC-721 or ERC-1155). NFT owners often earn 110–150% of floor; players get affordable shots at high-value NFTs. Creator does not auto-join.
