For example, if £100,000 is wagered on a game, and £95,000 is returned to players, the RTP is 95%. Higher RTPs give players better odds of winning in the long run, though it doesn’t guarantee short-term outcomes. Remember that the RTP is the return to player percentage, meaning the game returns £96 for every £100 wagered over time, not just in a single session for one user. For example, if £100,000 is wagered on a game, and £95,000 is returned to players, the RTP is 95 per cent.

It represents the average gross profit that the casino, or ‘house’, can expect to make on the game. RTP is calculated based on the total wagers and winnings over a large number of plays – usually 10,000 or more.
