Casino Guide to RNG Games

An RNG is a computerized electronic device that generates sequences of numbers randomly. It is used in casinos because it is seen to be a fair way for the casino to calculate its edge. The RNG will undergo rigorous testing to confirm its randomness of sequences. There are three areas in a casino where RNG machines are utilized.


There are currently two types of slots that can be played in a casino. The first is the old fashioned “one armed Bandit” machine. These types of machines do not use RNG technology. Modern slots with mechanic reels (3, 4 and 5 reel) use RNG technology. These slots give the players many different variations on playing the game. The number of winning lines on any slot machine can be determined by the casino. A three reel slot may offer the player the choice of horizontal and/or diagonal win lines. Some three reel slots offer the player an option of playing a nine win selection. Each window of each reel spins independently giving the player a much great chance of being awarded a winning line. These slots are also played in online casinos and there’s no better way to learn all the details than experience the game by yourself.

Random Number Ticket Games

Random number ticket games are basically classified under two heading:


Bingo is a random numbers game that is played with 90 numbers. All players buy books of six tickets. Each ticket has 15 numbers printed on it. The numbers are called and the game concludes when a player has cancelled all 15 numbers of their ticket.


Keno is a random number game that is played by marking a ticket. The player selects 20 numbers from the 80 on the ticket. All 80 numbers are marked on balls, in a bubble. 20 balls are randomly selected and entry tickets are compared to the drawn balls. The winner is the ticket that shares the closest match to the drawn balls.
