haha be careful with gambling on this site.. I invest some money there and I get all back next day (thank God I cashout same day 
).. But day after I got 22 time LO in row and lost all.. So I think that this isn't provably fair HI-LO game 
Look like they have big House edge.. So rather try somewhere else to gambling ..

The High-Low multiply game has a 5% house edge, but each roll is based on your clients seed and the servers seed hash and is provably fair.
The order things are done when you hit roll.
1. Two strings are created :
STRING1 = "[NONCE]:[SERVER SEED]:[NONCE]"
STRING2 = "[NONCE]:[CLIENT SEED]:[NONCE]"
2. Then HMAC-SHA512 is used to hash STRING1 with STRING2 as the secret key, giving us a 128 character hex string.
3. The first 8 characters of the hex string are taken and converted to a decimal.
4. This decimal is then divided by 429496.7295 and rounded off to the nearest whole number.
5. This whole number is used as your roll, with the maximum possible value being 10,000.
