Seeds In the provably fair tab, users can change and verify seeds used. To do this, click "Rerandomize" near the top of the provably fair tab. Before you specify your own seed, you are shown the SHA256 hash of the server seed that will be used alongside whichever seed you pick. Changing the client seed used will also reveal the previous server seed, which you can then verify was the seed we hashed and showed you. Roll Numbers
