We use same system as bitzino - in fact, you can take values and paste it to bitzino.com/about/fair and verify... All i can tell, see your game history - right next to "new game" button, click on "verify provably fair game".

See your cards at "4. Final Table" and you can easily replay whole game with real cards on desk - eg. http://bitsolitaire.com/verify.html#client_seed=cHQw7L6V5ls0cSc0gpZB1VcSzrXeZwjH&final_shuffle=zycrLmG7O4Ng63Jj80do2FlvMBuAhnawqD5bfse1PtkIpxCE9KHi&hash_secret=0b259a2f0e9e6b09d2bc21e47bc9c42b395af2ff0f35a584072b68e611ef97c3&secret=%7B%22server_seed%22%3A%22FEM%5E4q%23~I%2FK4w%3Fb%60NK_7Mq%265%3CF%3F_%3Dn%40N%22%2C%22initial_shuffle%22%3A%22Ous0rlL2mcaJPnDB3Mk1qFKoe76AEGvix5pbgjtdHCIzfNh8wy94%22%7D
