What is RTP, and what does it mean for online casino players?

Before we go any further, we should perhaps explain RTP (Return To Player) in more detail for us UK players.

What is RTP, and why do you need to know about it?

Return To Player, or RTP, isn’t just a fancy term. A neat percentage shows how likely an online slot will pay out over time. Think of it as a tip-off on where to place your bets. A higher RTP means more cash in your stash so that you can enjoy a good time spinning those reels.

How important is RTP for a player?

Higher RTPs offer bigger rewards over time, yet each spin may not be a jackpot. A slot with an RTP of 94% may target lucky jackpot winners, who frequently have lower RTPs.

Volatility and hit rate are the magic. Low volatility yields frequent but small wins, while high volatility is unpredictable but can yield huge payouts. RTP doesn’t guarantee payouts. If bonuses drive that RTP, make sure they’re easy to win.

What’s the difference between RTP and Volatility

Volatility refers to how often a slot machine gives out payouts, while Return to Player (RTP) indicates the percentage of total wagers that the casino game returns to british players as winnings. For instance, if there’s a penny slot with an RTP of 90%, it signifies that the slot pays out £90 in winnings for every £100 wagered.

It’s important to note that both high and low-volatility slots can have the same RTP, illustrating that the frequency of payouts and the average amount returned are distinct aspects of the game.
