Rolex? 1 in a billion? Yeah, why not?
It may worth mentioning that, the chance of winning the $15,000 Rolex is even lower.
Every time you spin the wheel of fortune, a random 8 digit hexadecimal number is calculated and is converted to a decimal number. That's divided by 4.294967295 and then rounded down to the nearest whole number.
The only 8 digit hexadecimal number that can give you 1 billion is FFFFFFFF. This means that the chance of winning the $15,000 Rolex is 1 in 4,294,967,295.
That's interesting, I didn't know this.
I believe the maximum number of WOF spins you can get each day is 238 (someone please let me know if I'm missing any):
16 if you have been a level 7 premium member for 360+ days
2 emailed to you (1 promotional email, 1 daily wagering stats email if you've wagered >500 sats that day)
100 from the "Exchange RP for WOF" option
120 if you redeem the 5 WOF spins / roll reward and do a 24 free rolls over the next 24 hours
Based on the 4.2 billion number you gave, if you get 238 WOF spins per day, you will, on average, win 1 rolex every ~49441 years
