Online Slots RTP: What Does It Mean?

RTP is short for Return to Player. Percentage return to player (% RTP) is the expected percentage of wagers that a specific game will return to the player in the long run..

Each online slot game has its own RTP, and this information is made readily available by the casinos.

Many players are interested in finding the slot machines with the highest RTP, since these are the games that theoretically pay out the most amount of money over time.

However, it’s important to remember that all outcomes are random and just because a slot has a high RTP it doesn’t guarantee you a win.

That said, let’s take a closer look at the slot games with the highest RTPs around. Read on to find your new favourite!

Mega Joker

RTP: 99%


Mega Joker has an impressive 99% RTP, making it a firm favourite with players worldwide. This entertaining slot game has a classic fruit machine style, with a design that mimics traditional slot machines plus some fun fruity symbols. Although the game doesn’t have any bonus features as such, it does have a Super Meter AND a progressive jackpot that more than make up for it!

In the Super Meter game, more money is at stake but the potential prizes are higher. Activate it by landing a winning combination in the base game — or you can hit ‘Collect’ to continue playing the base game. 

Match three jokers in the base game to win the progressive jackpot!

1429 Uncharted Seas
