One shared round for everyone, run by a Solana program on devnet. Each tick of the chart is one Solana slot, decided by that slot's hash and a secret number committed before the round. Devnet SOL is play money with no value. Working name.
Waiting for a round to finish.
Re-check a finished round from Solana's public record, in this page: the secret numbers hash back to the commitment made before betting, and every tick is recomputed from its slot hash and number with the program's own rules.
