I had the same idea not long ago but scrapped it. I asked a couple staff if it was an idea that would be allowed, and they said if it's completely legit it would be allowed, but they advised me against it because people take their cubits seriously so you may need to log every transaction/ticket and record the wheel spin and maybe even prove it's your first time spinning it. If you do it, I think you should make the tickets 0.1 cubits because 0.01 is way too little, I even thought 0.1 was a bit low.
Not that I would participate anyway
