The Award Winning
Online Casino

Mr Green online casino

Welcome to Mr Green - the gentleman among online casino Ireland operators. At Mr Green, our primary focus is entertainment as well as providing a safe and responsible gaming environment. Our approach, that makes the customer our top priority, has seen us win several awards within the industry across the years, including the IGA Online Casino Operator of the Year 2013, 2014, 2015, IGA Online Gaming Operator of the Year 2017, and SBC Award for Socially Responsible Operator of the Year 2017.

What is an Online Casino?

Online Casinos are the equivalent of traditional casinos and high street bookmakers in Ireland, but brought to you with ease online. In online casinos punters play and wager on online casino games such as slots and table games through the internet using a computer or mobile phone. Betting online can often give you more freedom than placing wagers in-person, as you can tailor your bets how you please and can occasionally get enhanced odds, which are unavailable elsewhere. The games offered by casinos are often rented or bought from game providers such as NetEnt, Yggdrasil Gaming, Play’n Go, Microgaming, and Playtech.

Different platforms and live gambling

At Mr Green, we have plentiful options if you like to play casino online. You’ll have the freedom to play from your computer or from the comfort of your mobile phone or tablet – all you need is an internet connection! This applies to casino, live casino and sportsbook, including live betting.

Live casino

There are plenty of choices as to which live casino game you play with Mr Green. You can play traditional table games like Blackjack, Roulette, Baccarat and Poker, with professional live dealers manning the tables. We have many tables for each game, including Texas Hold’em, Caribbean Stud Poker, and exclusive Mr Green branded tables. Playing in our live casino is a unique and fun experience and is the closest thing available to playing in a casino in-person.

Mobile casino

Many people’s preferred method of gaming is on their mobile device. With Mr Green, you get a seamless and mobile friendly application that is available to play on smart phones. With this app, you can access Mr Green's casino and most of its games from almost anywhere as long as you have access to internet.

Live betting

Live betting can change the way you experience sporting events. At Mr Green, you can place live bets on a huge selection of sporting events, such as GAA, Football, Horse racing and more in our innovative Sportsbook 2.0. Live betting simply means that while the event is being contested, you can still place bets on it. It can be a very exciting way to bet, as it gives bettors access to markets that are unavailable prior to the event, such as who will be given the next corner kick or yellow card. In addition, in live betting you still have access to more traditional markets such as betting on the outcome of the event. With Mr Green’s Sportsbook 2.0 you can also benefit from using our ground-breaking Bet Assist tool to get a competitive edge when placing your bets.

Apps (Android and iOS)

For those that enjoy gaming while on the move, the Mr Green smartphone app is the perfect tool. The app is available on both iOS and Android devices. It offers a slick and comprehensive gaming experience that can be navigated intuitively and packs lots of great features. With the app, you'll have access to your favourite live casino, slots and keno games, as well as the ability to back sporting events - all at the press of a button. You'll also be able to easily and securely deposit and withdraw funds within the app. There's 24/7 access to customer support for any queries you may have. The app also has the built-in Green Gaming tool, which makes it quick and easy to set limits for deposit, loss, or wagering.

Different Casino Games

You’ll be able to play all kinds of casino games with Mr Green. The classic casino games can be divided into two types: slots and table games (e.g. Roulette and Blackjack). In addition to these traditional games there is also the option to bet on number games such as Bingo and Keno and the extensive Sportsbook that allows you to bet on sporting events. Below, we will have a more in-depth look at some of the games available.


Online Casino slots are just like the slot machines that can be found in traditional casinos. They usually have between 3 and 5 reels and can be played through your Mr Green account quickly and easily. The player sets the bet level and then pushes a button to spin the reels. Certain combinations and patterns of symbols result in wins when the reels stop spinning. Most online slots include extra features such as free spins, bonuses, and wilds. Below you will find a more detailed look at some of our games:


Starburst is a fast and colourful game with five reels and ten pay lines. As the name suggests, the game has a space theme and lots of fun and exciting features. One of the most exciting features of this game is the Starburst Wilds, which appear on reels two, three or four, where they stay in place for up to three re-spins at no additional cost.

Gonzo's Quest

Join the little adventurer Gonzo, as he goes through the jungles of South America in search of El Dorado, the lost city of gold. Great graphics, quirky animations, and lots of exciting special features all combine to make sure you have a great experience while playing this fun slots game.

Twin Spin

In Twin Spin, every game round starts with identical, adjacent dual reels that are linked together. For each spin, the dual reels can expand to become three, four or even five-doubled reels. With this unique feature and the 243 ways to win, you will have tons of excitement on every spin.

Rainbow Riches

Rainbow Riches is one of many slot machines with a Leprechaun theme. It's a fun game with exciting features like Bonus Rounds, Pots of Luck, scatter and wild symbols, and a bonus round called Pick Me. The most important symbol of this slot machine is the Leprechaun Gold Coin, which is a Wild that helps generate winning combinations by switching with other symbols. Also, keep an eye out for the Leprechaun's Hat, which is a scatter that triggers the bonus round.

Mega Moolah

Mega Moolah is an Africa-themed jackpot slot game. The game offers multiple ways of winning rewards on a unique combination of five reels and twenty-five pay lines. Lions are wilds that can double your winnings. Trophy Hunters are scatters, and if you get one of these, you will be rewarded with fifteen free spins and tripled winnings when you play and win with these free spins. It's an exciting game in an interesting setting that offers plenty of ways to win.

Book of Ra

Book of Ra is an Africa-themed jackpot slot game. The game offers multiple ways of winning rewards on a unique combination of five reels and twenty-five pay lines. Lions are wilds that can double your winnings. Trophy Hunters are scatters, and if you get one of these, you will be rewarded with fifteen free spins and tripled winnings when you play and win with these free spins. It's an exciting game in an interesting setting that offers plenty of ways to win.


In roulette, players bet on either red or black, a single number, groups of numbers, odd or even, or high (19–36) or low (1–18) numbers. At its core, the game is as simple as that. After the bet is placed, the wheel is spun in one direction and the ball in another. The ball slows down and wherever it settles determines the bet. There are 37 pockets on the wheel, all of which are numbered and are either black or red (with the number zero being green).

Sportsbook & sports betting

The Sportsbook is one of the most popular betting categories with Mr Green. With the Sportsbook, you can bet on many sports and events, including football, ice hockey, tennis, boxing, mixed martial arts and also sports and competitions that may particularly interest the Irish market such as GAA and the League of Ireland. It's not just sports that have available markets either - you are also able to bet on political events and competitions such as the Eurovision Song Contest. How you place your bet will vary depending on the sport, but it's always easy to understand with Mr Green. There are also plenty of live betting markets available so you can bet on events as they happen.


Mr Green offers many jackpot games where there are large amounts of money up for grabs. Many of these jackpots are progressive jackpots. This means that the prize money increases each time the game is played but the jackpot is not won, making for huge potential winnings.


You can't think about a casino without thinking about Blackjack. Sometimes known as 21, it is perhaps the most popular table game in the world. You may be playing with several people when playing Blackjack, but you're not playing against each other - everyone is playing against the dealer. You play the game using one or more decks of cards, and the aim of the game is to beat the dealer by getting 21 on the player's first two cards (which is called a blackjack), by reaching a final score higher than the dealer without going above 21, or by letting the dealer draw more cards until the hand exceeds 21.


Baccarat is a card game that is contested between the player and a banker. Cards two through nine are worth their values in points. Tens, jacks, queens and kings are worth zero, and aces are worth 1 point (jokers are not used). A hand is valued by the rightmost digit of the sum of the cards, and each round has three potential outcomes - the player gets the higher score, the banker gets the higher score, or a tie. The hand that is closest to the number nine is the winner. There are three variations of bacarrat (Chemmy, Banque and Punto Banco) and each of the variations have their own unique differences.


In the game of Keno, players choose numbers from a board that ranges from 1 through 80 (there can be variations on this). Then 20 numbers out of the 80 are randomly drawn. The amount a player wins depends on how many of the randomly drawn keno numbers match the player’s chosen numbers, how many numbers the player chose initially and finally, the amount the player wagered. The player can check the pay table to work out how much a wager and match combination would win. At Mr Green, there is a Keno draw every minute with potential to win 100,000 euros on each draw.

Responsible Gaming - Green Gaming

Green Gaming is Mr Green’s take on responsible gaming. In 2017 we launched a predictive tool that analyses the actual playing behaviour of a customer and the customer's own perception of his or her behaviour. Using this tool, our customers can receive personalised insights and analyses about their gaming behaviour. If a customer's behaviour is risky, we can adjust our offerings and communications to that customer. For example, customers that exhibit increased risk behaviour may be asked to set different limits for their playing or to take a break from playing for a period. We will also refrain from communicating sales messages to customers with increased risk behaviours. We believe we are leading the way with our Green Gaming approach and are very proud to have won the following awards:

  • 2017 SBC Socially Responsible Operator of the Year
  • 2018 GGA Corporate Responsibility Provider of the Year
  • 2018 IGA Social Responsible Operator of the Year
