100% of the money raised with ticket sales will be paid out to the three winners and on top of this the site will give out another 1%! Players with winning tickets will win an extra 1% of the prize pool.

I'd say the provably fair tabs on each game are a great starting point.
Everything is explained in detail on there, and you even have a third party verifier linked with each bet.
That should be sufficient information to allow you finding the answer to your question.

I might have figured it out.   It only occurs when I'm use the max win chance "1.02x" ... so probably the C# might be sometimes sending something slightly less.   At least that is my current guess, I haven't actually captured the packets to check it out yet.  


EDIT:  I had a bug where I set my reward to 1 and then it sent a chance that is too high, that generated the "Invalid Ratio" which is a bit of a cryptic message.   "Chance too high" would have been clearer.
