Are you joking? Because I ever saw someone hit 99.99 or even 0 to make a big hit and now you said that their client doesnt let us hit that? You should check their big winner tab and then you can post something like this
U understand me wrong. I said that they only allow u to change the outcome by 50 %. So whatever Serverseed they give you, you can maximal add 50 % to it.
So if they give u ServerSeed of 2,147,483,648 then your outcome can be in a range between 50 and 99.99, depenedent on the ClientSeed you pick. But with this given ServerSeed it would not be possible to have an outcome below 50.
To better understand that I recommend to just try to calculate your outcome for an example. It's really not hard to do.
Server can chose a seed between 0 and 2^32 and the client only between 0 and 2^31. The sum of both numbers devided by 2^32 will be your roll result.
You will notice that u can only change the outcome to a 50 % range between the possible 0 and 99.99.
And which range this is, get's basically defined by the ServerSeed you get provided.
