How to play free online games

In many countries, slots are some of the most popular casino games, and as a result of the innovative improvements that gaming companies like Novomatic or NetEnt offer, their popularity is constantly growing. Obviously, in addition to the frequent searches for free online casino games, there is another subject of great interest for players: how can I win and what are the strategies that help me beat the casino?

First, and perhaps most importantly, you need to understand how to play online, and then experiment with as many free online games as possible. Only by doing so will you discover what you like and what motivates you to be persevering. On our website you can choose from hundreds of free games. It’s 100% free, no registration needed!

If you are a beginner, the slots are the best option to get acquainted to online gambling. The rules are simple and differ very little from one game to another.

On our site you will find free games from Novomatic, Microgaming, iSoftBet, Quickspin, NetEnt, EGT and other top manufacturers.
The advantage of being able to start playing online slots directly provided by top software companies is not to be neglected, especially if you take into account the fact that you do it for free. Not to mention the spectacular graphics, video and audio effects – offered by Microgaming, NetEnt or EGT, which are at an unbeatable level at the moment, so the game is not only fun, but also introduces you to the atmosphere of the story.

Every month there are new, entertaining slots being released with features that are getting more advanced, bringing new levels of excitement. Even though the slots are evolving, they are more or less all based on the same type of symbols, which makes it really easy for you to learn and get to know a new game as long as you just know these different types.


Paylines are the lines on which the matching symbols must appear for you to win a payout. Typically slot machines have 20 paylines, though some have only 5 or 10 and some can have 50, 100 or even as many as 250. Sometimes paylines are fixed so that all the paylines are in play each spin, while other slots let you change the number of paylines you bet on each spin. Generally, the more paylines you play, the higher your total bet will be.


Slots have different ways to change your bet. Some slots allow you to select the size of your bet by changing the coin value, others let you also change your bet level, while others also let you alter the number of paylines in play. All of these options help you select the right bet per spin for your bankroll, depending on how much money you want to risk on each spin.


You can find out more about the game you are playing by clicking on the information button which can usually be found at the bottom of the screen. This button can be a tool symbol or a question mark. This page will let you read the game rules and learn how to trigger the bonus rounds. You can also see the paytable where all the symbols and their payouts are displayed, along with the rules for any scatter and wild symbols.

Slot games have symbols related to the theme of the game. They also have some special symbols, which can award bonus rounds, bigger payouts and multipliers. Some symbols can substitute for others to create more possible wins. Here are the main special symbols you will find when playing online slots:

Wild symbols

Wild symbols transform into any other symbol to achieve a winning payline. As such, you can use Wilds to increase your bankroll during your online slot game.

Wilds are also helpful for players as they can represent different things in a slot game online. Some Wilds stay on the reels for the next spin (Sticky Wilds), while others stack up (Stacked/Expanding Wilds) or move along the reels (Creeping Wilds).

The number of Wilds also varies between slot games. Some include just one while others feature many; the more Wilds that feature in a game, the more wins they generate for the player.

Scatter symbols

Scatters symbols are slightly different from Wilds in that you can activate them outside a payline, as well as on an active payline.

There are various outcomes of using Scatter symbols in online slots. These include unlocking: mini-bonus games, free spin rounds, special Wild symbols, multipliers, or a combination of the above.

Wild symbols and Scatter symbols appear at random and may not feature in every online slot game. 

Choosing an online slot game

With more than 300 online slots games to choose from at Mr Green, how do you decide which game to play first? A vital first step to choosing the right online slot for your playing style is to consider volatility.

Volatility (sometimes called ‘variance’) is the relation between stakes of a slot game and the size of the pay-out. The volatility rate is usually categorised as either low, medium or high volatility.

  • Low volatility games are those with smaller stakes and smaller pay-outs. These are the most common type of slot game as they deliver more winning rounds and help to build up a bankroll slowly.

  • High volatility games have higher stakes and higher pay-outs (jackpot slots are an example of a high volatility game). You may be less likely to win in a high volatility slot game, but the returns are much larger.

  • Medium volatility games are those which sit in-between the low and high volatility options.

If in doubt, we advise players match their online slot games with their bankroll and experience level. For instance, if you are a beginner or have a low bankroll, you should choose a low volatility online slot. If you have a higher bankroll and are prepared to risk more for greater rewards, a high volatility game is more suitable.

To ensure you always understand the risks of each game you play, we clearly display the volatility rate in each of our slot games online – just view the pay-table for all the information you need.
