The gameboard consist of six squares where you can place your bets and a croupier that handles the dice and bets. The croupier rolls two standard, fair, six-sided dice inside an inverted cup so that nobody can see the result. Each player bets on a number from 1 to 6.
If none of the dice shows your number you neither won nor lost. Your bet remains on the table (some variants allow the withdrawal here or change of number but generally this is not allowed).
If only one of the dice shows your number you lose.
If both dice show your number you win, collecting 9 times your bet.
The gamblers reasoning goes like this:
“If none of the dice show my number I neither win nor lose so that’s OK. If one of the dice show my number there is a 1 in 6 chance the other one will as well so if I get more than six times my money I'll gain on the average.”
Most Dhe tables generate quite a lot of cash so obviously the reasoning above is flawed.
