Really and addicting game! Wish I could deposit and bet smaller amounts because I am a bitcoin peasant at the moment, but the fountain is definitely generous. Definitely my new go-to and glad I stumbled across this on the forum

Nice work!

Playing right now, I really like the concept. My question to you is, is it provably fair?

Thanks, glad you guys like it!

It's 100% provably fair because a future block on the Bitcoin blockchain is used to determine the winner, which can't be manipulated. Fairness can be independently verified by making sure that the "Block Hash" matches the stated block number.

Open source code is also available to verify each of the available games:
