Quick explanation:
Result of each round (Game's "Fly away" multiplier ) is not generated on our servers. It's generated with help of round players and is fully transparent. This way, it's impossible for anyone to manipulate game output. Also, anyone can check and confirm game fairness
More information
The round result is generated from four independent participants in the round: the game operator and three random players from the previous round. The operator generates a server seed (a random 64-character string). Each player generates a client seed on their side.
When the round finishes, the game merges the server seed with the three client seeds. A SHA512 hash is generated from the merged characters, and from this hash, the game result is derived.
A hashed version of the combined seed, excluding the 8 result characters, is publicly available before the round starts (In the user menu, check "Provably Fair Settings" and then "Next Combined SHA512 Hash Without Result").
