Like you read above, the game involves players participating in a lottery. The contract uses Chainlinks's VRF (v1) to randomly then choose a winner, and award all the collected entry fees combined.
The Graph protocol is used to index all the games that are played, and are queryable at "https://api.thegraph.com/subgraphs/name/captain-woof/lottery-dapp-v1".
