Habbo Hotel Dice Rigger?

Ok, on the game Habbo Hotel, there is these things called Holodice.

When you roll them they can be a random number from 1-6
I was wondering if you could rig it so you could choose any number out of those 6, so if you were betting in a casino...you could always get 21 and win a ton of furni. Any suggestions?
