The bet menu on site has been designed to help you locate events by order of sport, for example Football, Formule 1, Tennis or Esports. Can’t find the particular event you’re looking for? Try the sports locator search function. Just enter a team, name of a particular player or country.

Mr Green has even included a quick filter if you’re looking for LIVE odds for matches that are being played as you bet. Or for events that are starting soon. These are useful if you would like to place your bet and have it resolved (paid out) sooner.


Once you have found a match or event you are interested in, you can open it to view all the possible “bet markets” (learn more about markets further down) available for you to bet on.

Odds are simply a reflection of the chance or probability of a certain outcome in an event or sports match. In any event, every outcome has a chance or likelihood of taking place. Odds are simply an interpretation of those chances. A bookmaker will form odds or prices to reflect those chances.


The odds on screen look strange, I’m used to seeing other odds? Most online bookmakers like Mr Green give you the option of which type of odds you want to use. The odds can be displayed in decimal, fractional or American format.

On the Mr Green sports betting page, simply select the drop down menu to choose the odds display that you feel most comfortable with.



Decimal odds are most commonly used throughout mainland Europe and are also commonly known as ‘European odds’.

It’s super easy to understand how decimal odds work and how much you can win if the bet goes your way. Basically, you multiply your stake by the decimal shown and the answer is how much you’ll receive in winnings – including your stake.

For example, if you bet €20 on a wager with the odds 2.00, the payout will be: €20 x 2.00 = €40.

Conveniently, all this information is clearly displayed on the web site, so you do not need to calculate this by yourself.



Odds displayed as fractions show how much you will win on a bet compared to how much you put on it. The first number in the fraction shows how much you will win if you place the amount shown in the second number. Fractional odds are most commonly used in the UK.

For example, odds of 2/1 tell you that for every one (1) euro you stake, you will win two (2) euros. If on the other hand you saw the odds 1/3, this indicates that you will need to stake three (3) euros in order to win just a single euro.

For your convenience, the payout is automatically calculated and displayed on the web site, so you will never need to calculate this by yourself.


There are two main betting methods in sports betting: pre-match bets, and LIVE bets for betting during matches.



Pre-match betting takes place before a match begins, even up to a year before the match begins and concludes once a match starts.

Pre-match betting involves successfully being able to predict or foresee particular outcomes before the events have started, then wagering on that event to happen or not happen.

Example: placing a bet on Leicester to win the 2015/2016 Premier League season before the season had begun, the odds were a huge 5000/1 – a €20 bet would have won you €100,000 a little less than a year later!



LIVE betting takes place after an event has started and up to its conclusion.

Watching an event LIVE and being able to appropriately predict and respond to a given situation, are the two most important factors in LIVE betting.

Example: During LIVE betting Tennis, players can bet on the next point, games to deuce, total points in a game, total games in a set, set score, plus a host of other markets. In LIVE football, you can bet on the half time result, next team to score, next corner, next goal scorer, plus the winner of the match and many more markets.

The odds change during the game depending on the performance and positioning of the team and players.



A single is a bet on 1 selection in one event. Your selection must be successful to get a return.

Each way

Commonly used in horse racing or any event with a tournament based qualifying format, an ‘each-way’ bet is a wager that consisting of two separate bets: a win bet and a place bet.

For the win part of the bet to give a return, the selection must win, or finish first, in the event. For the place part of the bet to give a return, the selection must either win or finish in one of the predetermined places for the event, such as first place or second place.


Also commonly referred to as an ‘Acca’, a combination bet is one bet requiring a selection of multiple bet markets on a single bet slip, the only difference being that ALL the selections must win to have a return.

The advantage of a combination bet is that winnings are much higher at the expense of increased risk. The only drawback is that it takes just a single selection in the combination to lose, for the entire combination bet to lose.

To place a combination bet, select the markets you would like to bet on so that they appear in your bet slip. Select the ‘Combination’ tab to combine the selections and enter the stake you want to wager. The bet slip will calculate the potential payout for your combination bet.

Please note that some bet selections cannot be combined. The bet slip will notify you if any of your selections are incompatible.


A system bet is made up of several combination and single bets. As soon as you have added at least 2 or more bets to your bet slip, you can place system bets. To do so, click on the ‘System’ tab to see the number of possible system bets available to you based upon your bet selections.

Below are examples of combination bets and system bets. The number of bets selections (markets) that are required on the bet slip and how many combinations a particular system bet creates.


To place your bet, go through the following steps:

1. Find a bet you like, for example “Ajax – Chelsea”
2. Click on the outcome you want to bet on, for example “Liverpool to Win” – a bet slip will open up with your selection on it
3. Enter a stake in the bet slip
4. Click “Place bet” and wait for the bet slip to be confirmed.
5. Your bet is now placed. You can view all the details for the bet in the betting history
