[1] The UK Gambling Commission allows customers to be informed about the risks in the form of Return to Player or house-edge percentages.
For example, a casino may inform the player about a payout percentage of 90%, which means that for $100 bet $90 is going to be returned.
Both variants are identical, however in accordance with the so-called framing effect, there is a certain influence on players due to different ways of perception.
[3] All the slot machines at Crown Perth in Australia have a 90% minimum Return to Player percentage.
