Matthew, thanks for your comments.
The concept is the answer to all those games that require some form of hash/seed and calculations to verify fair results.
In our case the hash of the block that confirms a transaction is also the winning number.
I have not seen any game based on this simple principle and I wanted to point this.
Thank you for your response. I'm actually referring to any and all "blockchain" games actually, and didn't mean to downplay any specific complexities or innovations in yours. Just think of it like we're rating pop music and I only like classical-- I'm not good for a 10/10 on this one, but since you seem to use the same method we use for raffles around here, that is worth something. I've edited my previous score. Cheers.
