Before continuing, please make sure you have read the ‘points to note’ on the previous page. Then, carefully follow the steps below to unlock free bet credits. Always complete account verification before moving onto Step 2 and depositing.
For the most profitable outcome, this offer requires you to have an account with a betting exchange. If you do not already have one, click here to read our quick guide on how to get started. A basic knowledge of exchanges will be helpful - also covered in our guide (4 min read).
Step 1:
Sign up to Grosvenor Sport here, completing the account verification process if required.
Step 2:
Deposit a minimum of £20 with a debit card and, when prompted, opt in to the casino welcome bonus when depositing. We suggest a higher deposit (£40), mentioned in our ‘Points to note’ on the previous page.
Step 3:
Use your boost:
Grosvenor Sport are offering the chance to double the odds of any bet. To take advantage of this follow the instructions below:
Find a Horse race later in the day (a few hours later to give yourself time to complete the whole offer before the race), compare the doubled odds to win on Grosvenor Sport, with the lay odds on a betting exchange for the same horse. (To double the odds you must multiply by 2 then subtract 1. E.g. Odds of 4.0 will become odds of 7.0).
You need to find a situation where the doubled win odds on Grosvenor Sport are significantly higher than the lay odds on your betting exchange (this will be extremely common). The bigger the gap between the two the better. e.g. when the doubled Grosvenor odds are much higher than the exchange lay odds).
Choose the horse where the gap is the largest - place £10 on this horse selecting to double the odds on your bet slip.
Lay the same horse, staking the amount that will return the same as your bet on Grosvenor Sport is set to return.
Step 4:
The next 2 steps are complex and may be time consuming. You do not have to continue, and can end the offer here.
What next?
Grosvenor Sport are also offering a £30 casino bonus. However, they will use up funds from your cash balance before any bonus funds are used.
Therefore, you must place another bet with the remaining £10 in your balance (so your cash balance is zero). This way, the bonus funds will be used immediately. You cannot withdraw.
Find any sports event later in the week, compare the odds for one team/individual to win on Grosvenor Sport, with the lay odds on a betting exchange for the same team/individual.
Choose an event where the win odds for a team/individual on Grosvenor, and lay odds for the same team/individual are the closest - place your remaining £10 on this.
Lay the same team/individual, staking the amount that will return the same as your bet on Grosvenor Sport is set to return.
Your balance should now be zero. You must complete the next step before either your double odds horse or sports bet are settled.
Step 5:
Use your casino bonus:
When your balance is zero, open Big Bass Bonanza slots.
Your deposit and bonus funds must be wagered 30 times before withdrawing, on Big Bass Bonanza.
As the bonus is £30, and your deposit was £20, a total of £50 must be wagered 30 times (£1,500).
Step 6:
Keep playing Big Bass Bonanza with your bonus funds, until you either run out of bonus funds or complete the necessary wagering.
Patience is key and, as with all Casino offers, your success rate will be higher the smaller stakes used. E.g. Use £0.10 stakes rather than £2 stakes although it may be tempting to save time. Due to the large wagering requirement, a higher stake than usual may be appropriate.
Step 7:
Complete your wagering, and then head to the cashier to withdraw any bonuses remaining, as well as any winnings from your doubled odds bet.
