Winning opportunity
Ah! I have a great idea for Charles. When they push the button to make sure the dice don't come up with your numbers, you should notice what numbers they are making come up. Then make a a really big bet on the numbers they have been making come up. Take down your profit, then make lots of small bets on the same numbers. When you can see that they pressed the button again to make other numbers come up, hit them with the big bet again. Then repeat until they catch on.
