UK bookmakers: Free bets guide 
				  When placing a bet with a bookmaker, you place what is know as a stake (your bet   amount) on the outcome of an event at particular odds. Take a football match for   example, if you were to place £10 on Team A winning the football match at 3/1   (4.0 in decimal odds) you would win £40 (your stake of £10 plus the winnings of   £30), now if you lost the bet, the bookmaker would keep your £10 and you would   receive nothing. 
  Taking the above example, imagine you are the bookmaker   offering the same odds to someone for the same outcome, if the bet loses you   gain their £10, however if the bet wins you have to pay out £40 (£10 of their   money back, plus £30 of your money). This is known as 'laying' a bet and is   something which can be done on a betting exchange.
				  Now if you were to place the bet above and then lay the same bet at the same   odds (by using a betting exchange and acting as the bookmaker) whatever the outcome   of the match you would not lose any money, the bets would cancel each other   out.
				    With football there are two possible outcomes. Below are the potential outcomes of   placing the above bet/lay (matched bet):
				  Qualifying bet
                      Team A   wins
				    You win £40 (your stake of £10 plus the winnings of   £30).
				    Your 'lay' bet loses (with the betting exchange) meaning you lose   £30.
				    Therefore you would be left with the following £40-£10 (stake) - £30   ('lay' bet) = £0
				  Team A does not win (loses or draw's match)
				    You lose £10   (your stake)
				    Your 'lay' bet wins (with the betting exchange) meaning you win   £10
				    Therefore you would be left with the following £10 ('lay' bet) - £10   (stake) = £0
				    So by placing your bet and 'lay' you neither win nor lose any   money.
				  Now lets look at the same scenario as above but with a bookmakers free £10   bet
				  Free bookmaker bet
                      Team A   wins
				    You use the free bet of £10 at 3/1 (4.0). You win £40 without   risking your own money on the stake. 
				    Your 'lay' bet loses (with the betting   exchange) meaning you lose £30.
				    Therefore you would be left with the   following £40 - £30 ('lay' bet) = £10 profit
				  Team A does not win (loses or draw's match)
				    You use the   free bet of £10 at 3/1 (4.0). You lose the £10 free bet.
				    Your 'lay' bet wins   (with the betting exchange) meaning you win £10
				    Therefore you would be left   with the following £10 ('lay' bet) = £10 profit
				  This means you can place a qualifying bet as above with a bookmaker with no risk   whatsoever, in return you will be given a free opening account bet which if used   in the second example will generate a guaranteed £10 profit. Once you get the   hang of matched betting this can be done many times for each of the bookmakers with   opening offers.
				  Things however are not quite as simple as the example above. Betting   exchanges charge commission on winnings made at the exchange (usually 5%), also   it is fairly difficult to 'lay' bets at the same odds as the bookmakers, there is   always a small difference. Taking these factors into account it is still   possible to make 95% profit on the free bet without much difficulty and without   any risk.
				  Step by Step process
				    Once you understand the above   examples its time to follow the below step by step guide and place your first   matched bet.  
			      
Step 1
				      Find a bookmaker with a free bet (use the bookmakers uk list for current free bets).   
			      
Step 2
				        Open an account and read the terms and conditions to   determine the type of free bet and the conditions of using it, some bookmakers have   stake returned bets other may require the free bet to be placed on a particular   sport for example. If you are unsure then email customer service and ask what   the conditions of the free bet are.  
		          
Step 3
				          Open a betting exchange account, there is a link to Betfair   on the here which will also give you a free   £20 bet.   
		          
Step 4
				            If you haven't already, download a copy of this spreadsheet which will help calculate how much to   back/lay when placing matched bets. The spreadsheet also has the advantage of   being able to record the bets placed and keep a record of your username for   future reference.   
	              
Step 5
				              You now need to find a good match to use for the qualifying   bet, the aim being to place a back bet that has the closest 'lay' odds at the   betting exchange. This will produce the lowest loss in the qualifying bet. Enter   the bet odds and 'lay' odds into the spreadsheet to obtain the loss you would   make on the qualifying bet, play around with the spreadsheet so that you can   understand how it works.
				              You will need to look at the amount below the lay   odds at the exchange, this is the amount available to lay and should always be   more than the bet you are placing.
				              For example you may have entered something   similar to the following:
                  
                  
 
                  
This qualifying bet would result in a £1.25 loss with the free bet to follow.   It is important to make sure you back and lay the same event and try to get as   close a match as possible in order to reduce the loss of the qualifying bet.   There may be a rare occasion when the odds at the bookmaker are higher than the   'lay' odds at the betting exchange, this means you would make a small profit   regardless of the outcome.  
                  
Step 6
                    The next step is to deposit money at the bookmaker and deposit   money at the betting exchange which is more than the lay risk liability amount   in the spreadsheet.  
                  
Step 7
                    Once you have money in both accounts you now need to place   the bet. Take time when doing this until you get the hang of it in order to   reduce the risk of making a mistake. First place the bet at the bookmaker double   checking you have put the right odds into the spreadsheet. Then click on the lay   odds at the betting exchange and place the amount in the lay stake cell of the   spreadsheet into the betting exchange lay box (the risk should match that of the   spreadsheet). Both the bet and the 'lay' bet have now been placed.  
                  
Step 8
                    Repeat the process detailed above using the free bet to   extract the free bet money.
                    That's the process complete and the free bet has   been extracted. Now all that's left is to repeat the process to extract another   bookmakers free bet bonus!
                  Tips and Advice
                    Below I have listed some tips/advice that   you may find useful.
  
  Why choose football?
                    Football is an easy   market to choose when placing matched bets, this is because the rules are easy   to understand and also there is a lot more money available to 'lay' at the   betting exchange.   
                  
What are the best markets for qualifying bets?
                    The best markets to   choose when placing a qualifying bet are:
                    Win-Draw-Win
                    Under/Over 2.5   Goals
                    Half Time Result
                    First team to score
                    The reason for choosing the   above are that they usually contain fairly low odds and usually attract the most   money making it easier to 'lay' at the betting exchange.   
                  
Why use decimal odds?
                    Decimal odds are easier to work with as they   include the stake money in any return, therefore meaning they are easier to   calculate with.  
                  
Stake not returned bets
                    Some bookmakers offer free bets where the   stake is not returned. The key to extracting the free bet is to place a bet and   'lay' at slightly higher odds than the qualifying bet (above 4.0   decimal).
