Provability / fairness:

If you click on the question mark icon

then click on the microscope icon

then you should see a list of hashes of future seeds plus the results of previous races/grabs.

We publish the hashes of future seeds in advance so you can check they don't change when people play.
There used to be a detailed walk-through of using the seed, etc. but we removed it as it took up too much room.

Essentially there's a SHA256 hash of the seed and a fixed string to provide an integer that maps to a winner.

How to verify results ? Are the game results probably fair? I don't see any thing regarding fairness of the results, no secret key or seed nothing to verify results.

Also what is the house edge?

The idea is pretty dope actually..
But,how can I see if this is provably fair?

Thanks for the visitors today - and your feedback.

One aspect keeps coming up though:

Should play be on-chain or off-chain?

For on-chain play, there's no need to register, verify, load up an "account". All transactions/plays are viewable on the blockchain. But there's more of a hit due to fees. We actually contribute 0.0001BTC towards fees when sending winnings. Is that enough to make it worthwhile to players?
Players having accounts adds to the security workload of a website. We'd also rather not hang onto players' funds any longer than necessary. Both of these aspects make a website more of a target for hackers.

We were originally on-chain, then we changed to off-chain but then people complained about having to sign up!

Is the answer to implement both?
Or do players prefer on-chain for more peace of mind?
Or maybe it's a case of "you can't please 100% of the people 100% of the time"?
