STEP 1: Finding your Qualifying Bet

Video_Guide_IconTo view a video guide example please Join for Free here.

i) Switch to Decimal Odds Format

  • On desktop look for ‘Odds Format’ on the second menu bar and switch to decimal
  • On mobile click the menu icon and go to ‘Odds Format’ and select decimal

ii) Choose a popular league or cup

Examples include the Premier League, La Liga, Champions League, Euro 2020 etc.

To make life simpler for you we often provide lists of good Qualifying Bets to do in our Potential Bet Selections blog

iii) Select teams which have odds above the minimum odds of 1.51

For this first qualifying bet, we recommend selecting a team to bet on at William Hill with odds between 1.51 and 2.80. This is to keep your liability (balance needed in Smarkets) low.

For clarity, if you select a team with odds of 1.40 (which is below the minimum odds), and place this bet, William Hill will not then grant you your free bets.

iv) Check the Smarkets Exchange lay odds and choose the team which have the closest lay odds to the odds at William Hill

HOT TIP: Remember the lay odds at Smarkets are in the BLUE BOXES.

Ideally you need a maximum 10% (or around 0.2) increment between the back odds at William Hill and the lay odds at Smarkets.

For example, if the team you select at William Hill have odds of 2.3, your Smarkets lay odds should not be higher than 2.5. This is  to minimise your qualifying loss.

STEP 2: Calculate the Lay Bet Amount

Using the Qualifying Bet Calculator

You will now need to enter:

  1. Your stake amount at William Hills (e.g. £10 – which is the minimum required)
  2. Your back odds at William Hill (e.g. 2.30 were our example odds for Leicester to win)
  3. The blue box lay odds from Smarkets (e.g. 2.40 were our example odds against Leicester winning)

The calculator then works out your lay stake amount.

This is the amount you will use at Smarkets for your against bet.


> At this point you must always check the liability amount on your calculator. Your balance in Smarkets must be the same or larger than the liability amount. If your Smarkets balance is less than the liability, you can not do your Qualifying bet until you top up your Smarkets balance first.

> It’s also a good idea to check the liquidity available in Smarkets is greater than your stake amount (the liquidity is the small silver numbers in £ that are under your lay odds blue box) . Ideally your liquidity should be at least double your lay stake amount.

Checking Liquidity on Smarkets for Matched Betting

HOT TIP: £10 is the minimum stake needed to unlock the £30 free bets at William Hill. To appear as a good customer and increase your chances of unlocking more offers in the future you can bet £15 or more instead if you are able to.

STEP 3: Placing your bets

IMPORTANT: Remember to not use any odds boosts offered in your betslip by William Hill for this first bet. They may not give you the free bets if you do use it. 

The matched betting rule is to always put your bookmaker bet through first. So place your bet at William Hill.

As soon as your bet at William Hill has been placed and confirmed, you must now use your lay stake (as shown in your calculator) to place your against bet at Smarkets.

At Smarkets, just click on your lay odds in the blue box, write the lay stake amount in on your betslip, then click Place Bet and Confirm Bet.

STEP 4: Profiting from your Free Bets

Your 3 x £10 free bets are normally credited as soon as you’ve placed your Qualifying Bet. They will appear in your betslip. Usually they are valid for 30 days.

We now have to repeat the same process to do our Profit (Free) Bets that we used to do our Qualifying Bet – but with a few small changes…

i) Choose a team with higher odds to make a larger profit

We recommend doing each of the three £10 free bets separately on three different teams (from different games) if you can.

We need to find bets with higher odds in order to extract a larger profit from each of the free bets.

We have created a table for you below to see what amount of liability you will need in Smarkets to obtain a certain profit from each of the £10 free bets.


To help you out, we also talk about the best matches to place your free bets on in our weekly Potential Bet Selections Blog.

ii) Open the Profit Bet Calculator

Enter your free bet stake, with your back odds from William Hill and lay odds from Smarkets.

The calculator will work out the lay stake amount you need to use at Smarkets to make your profit. Here’s an example of what your calculator will look like:



Before placing your free bet, remember to do your two important checks: 

Smarkets balance is greater than the liability in the calculator

Liquidity at Smarkets (silver numbers in £ under blue lay odds box) is greater than your stake amount

iii) Select to use your free bets in the bet slip

As you know, you will make your profit using the free bets provided by William Hill, so don’t forget to select to use the Free Bet in your bet slip before placing your bet at William Hill.


HOT TIP: It’s good practice to double check everything before in your betslips before placing your bets. 

Once the free bet is confirmed at William Hill, then you can lay the bet off at Smarkets using the lay stake worked out by your Profit Bet Calculator.

Now all you have to do is repeat the process with your remaining two £10 free bets.


That’s another bookmaker down, and you should have made £15+ profit from these William Hill free bets – and you’re still just getting started!

HOT TIP – Fake Mug Bets & Checking your Email!

If any of your bets win at William Hill, consider making a few fake mug bets before withdrawing your cash. For these fake mug bets you can use any odds boosts offered by Hills. Each fake mug bet  will “cost” you around 40-80p, but they are a really great way to increase your chances of receiving private email promotions from them to make even more profit going forward…
