You specifically state that you will roll a number 1 - 20,000.
You're the saying the multiplier on a roll under 10,000 is 3.2x. Therefor you have a 50% chance of winning (You also stated this as 51% odd's - It's 50%) 3x your money?
You might want to recalculate...

Read again, it clearly says 21,000!
Also, the percentage adjusts itself based on dice rolls.
I coulda sworn it was 20,000...
And that makes no difference. a 10/21 chance of winning with a 3.2x multiplier is still a MASSIVE negative EV.
Your lucky someone isn't taking advantage of you right now. Then again this could be a ploy to make people think its their odd's for you to more or less take their money
