Percentage return to player (%RTP) is an amount of money that is used to play the machines, and is then returned to the player as prizes.

There are various kinds of rewards offered by gambling machines.

The %RTP is the average across a substantial number of games, but not for every game played.

The average %RTP is typically measured over 10,000 or 100,000 games in compensated machines. Random machines can have more games depending on the category they belong to.

Gaming machines do not require the minimum RTP.

Example:

If a machine that is gaming boasts an RTP of 85 percent it is not realistic to win an average 85 pence per PS1 you bet on during a gaming session.

Random machines

Random machines are based solely on the probabilities of an outcome occurring to meet their target percent RTP. The probability of winning in the current game is always. They are not affected or influenced by losses in the past.

Compensated machines

Compensated machines are also random. However, the chances of winning a prize vary depending on previous results. If return to player percentage is below the %RTP that it is aiming for, it may become more generous dependent upon design, or it may be able to pay less. Random chance is the primary factor that determines frequency as well as the amount of rewards.

House edge in casinos

Casino games, including:

• roulette
• blackjack
• Punto banco, for instance. are games for bankers and have an unequal chance.

The way that these games are played gives an advantage for casinos (the house). This is referred to as the house edge and it provides a measurement of the percentage of profit the casino should retain, on average from every hand or spin in the normal pattern of games.

Being apparent to players

Gaming machines should provide details about their class RTP percentage, and whether they’re either compensated or random.

This should be visible on every machine and could be in the form an indication or label that is placed on the machine. It might be displayed on a game help screen or on a different screen area within the game.
