The return to player percentage (or RTP) is the amount of money you can expect to win back over a long period. The RTP however is just theoretical, so while it does provide a good enough indication of just how much can be won over time when playing a game, it should not be dependent on. Another important point to note is how RTPs are inversely proportional to the house edge. This means that the higher the RTP, the lower the house edge. So for example, if an online casino game has an RTP of 95%, the house edge (money accrued to the casino from the wager) is 5%.
