What are the principles that are behind the idea of RC?
At the foundation of RC is the principle that the initial deck (for card games) or initial sequence of numbers (for roulette, the Wheel of Fortune and slots) does not change. After the initial deck (or sequence) is formulated and the computed checksum is shown to the player, the deck or the sequence doesn’t change. Players can introduce additional randomness by cutting the deck or selecting the order of the deck (for card games) or by using shift option for roulette, the Wheel of Fortune and slots. The checksum is used in RC for the same reason it’s used in cryptography: it guarantees that the initial data (the deck of cards or the sequence of numbers) doesn’t change.
