Not really – the figures are calculated based on thousands of wagers. For example, if a slot has an RTP of 96%, in theory, this means that for every £100 wagered on it, the slot will pay out £96. It represents the percentage of all wagers a slot will pay back over time. So even if you hit the jackpot, the terms might prevent you from getting paid out.

Playtech is not afraid to step out of the norms and always pushes new, cool ideas into the games. For example, if a game has an RTP of 94%, part of that percentage is used to fund the jackpot, leaving a smaller portion for regular payouts.

The prize pool grows bigger over time by taking a small portion of every bet placed and adding it to the jackpot pool.
