Hi,
I've developed a new coin flip game that can be played with Lightning on telegram.
https://t.me/lncoinflipbot

Deposit with any lightning wallet, flip for any amount of satoshis, withdraw your earnings instantly for free.

House edge is only %0.5 and everything is provably fair. I've included a quick way to verify the seeds, hashes and results.

Any feedback is welcome,

Feel free to check out my other lightning apps/games: https://kriptode.com


They have a verification tool, and that's great, but a verification tool doesn't make the site a provably fair one. Let me explain the problem. Users can't manipulate the client seed:

Quote
/provablyfair
Current game hashes are:
Server Seed Hash: aff7eccc891de69f877e363a1e2aec7172b5985535a207e86204ce0b221628c1
Client Seed Hash: d5cf9d43f2635ba4cd79190008b0c6743c6648056f14b598687d0d48a6ac50d3
Nonce: 1

And since the server provides both seeds, then the game is not provably fair because those seeds could be tested before the runs to warrant a looser seed for the long run.

To make it a provably fair game, users should be able to change the client seed before the bet.
