At MansionCasino, we guarantee that our casino provision is 100% fair. We use a Random Number Generator for all online casino games, and our payout percentages are displayed. A Random Number Generator (RNG) is a computer programme which randomly produces the game results. The RNG produces the outcome of each card deal and every dice roll, without any unrealistic duplication (such as two of the same card dealt at the same time). These results cannot be predicted, and are subject to games rules. The RNG is completely random and the results cannot be manipulated.
