The roulette wheel is numbered from 0-36 and when added up, the value of the numbers is 666 (six hundred and sixty-six). There are so many theories as to why this is the case, but one of the major ones is that Blaise Pascal, the father of the roulette wheel, is a prankster.
The mathematician created and designed the wheel, including the numbers, and it is believed that he added this little piece as a joke. There are other allusions to the number 6 that can be found by adding numbers across rows on the wheel.
The 666 number is known in religious circles as the devil's number. Many players believe it is a significant and deliberate addition to the game, which has moved them to nickname it the devil's game. It is hard to tell if this was a deliberate or accidental outcome, but the truth remains that it is a fun one.
