Gambling products may display how much money people can expect to lose over time. This information is typically displayed via the ‘return-to-player’ format (e.g., ‘this game has an average percentage payout of 90%’). Research suggests that the ‘house edge’ format (e.g., ‘this game keeps 10% of all the money bet on average’) is a better way to relay this type of information. This study compared the return-to-player format with two different phrasings (original and alternative) of the house edge format. The researchers found that the alternative house edge phrasing led to the lowest perceived chances of winning, but was not any better understood than return-to-player information. But the original house edge phrasing led to both lower perceived chances of winning and higher rates of correct understanding compared to the return-to-player phrasing.
