Online slots - choose between more than 800 slots at Mr Green

Sometimes known as ‘winning lines’, paylines run across the reels and dictate where matching symbols must appear for you to win from each spin. They come in many combinations and can appear horizontally, diagonally, vertically or even zig-zagging across the slot’s reels.
The total number of paylines can be anywhere between a basic 5 up to 250 or more. Some slot titles allow you to choose how many paylines to activate; others will be decided by your bets. The more paylines that are active, the higher the bet cost per spin will be.

Before playing, you’ll need to select your bet-value. This can either be done manually by changing the ‘coin value’ per spin or adjusting the total number of active paylines. This helps you to customise your online gaming experience.

Click on the info button, usually displayed as a wrench or a question mark symbol, to view a game’s paytable. This displays all of the game’s unique features and winning symbol combinations plus the list of possible payouts. You’ll also find the slot’s rules and bonus features explained, including how the scatter and wild symbols can impact your spins.

The exciting combination of bonus features, engaging themes, easy to master gameplay and fantastic potential payouts, have made slot games a top choice for many players. Choosing a slot game which fits with your budget and playing style can easily enhance your online casino experience.
No two slot games are the same. Some offer more regular payouts of smaller amounts whilst others payout bigger amounts but less often. This difference in the frequency of payouts is referred to as ‘volatility’ and is categorised as either low, medium or high.
Playing a low volatility slot will usually extend your gameplay by paying out smaller winnings on a more frequent basis. In contrast, a high volatility slot may payout bigger amounts less frequently. Slots classed as medium volatility sit between the two extremes and make an ideal choice for budget-conscious players.
A low volatility slot will typically pay you around 250 coins from its highest-valued symbol whereas, a high volatility slot can reward you with up to 10.000 coins.
It’s also worth considering the RTP percentage when selecting a slot game. This stands for Return to Player and represents the percentage that a slot could pay back for every €100 wagered. An online slot game with an RTP of 95% would payout €100 for every €95 wagered. Remember that this average is calculated over millions of spins, and your experience of a game can differ greatly.
Looking at a game’s paytable should tell you all you need to know about its specific volatility level and RTP percentage.

Jackpot slots offer players a chance of winning potentially huge amounts from a single spin. They come in two flavours, progressive and fixed.
A fixed jackpot has a set prize fund to be won at random, whereas the main prize pot increases with every spin on a progressive jackpot slot-potentially reaching millions of euros. A percentage of each wager contributes towards the total prize fund with games often linked between multiple casinos. This helps the jackpot to grow rapidly in a short time. It’s also not uncommon to see a mini, maxi and mega jackpot on offer in the same slot game, giving you more prizes to play for.

A typical myth about online slots is that they can go ‘hot’ and payout more, or, ‘cold’ and payout less. Playing any slot game is totally random, and each spin is entirely independent of the next or previous one. Online slots simply don’t go hot or cold.
It’s also untrue to think that jackpots cannot be won progressively. Each spin of a jackpot has an equal chance of winning the top prize, and there is no set time between jackpot payouts.
