Jackpotjoy Sign Up Offer

This offer is for a casino promotion and differs from a regular betting offer. If you are unfamiliar with casino promotions, read my Casino Offer Introduction first.

Sign up to Jackpotjoy, and when you wager £10, you’ll receive 30 free spins for the slot game, Double Bubble.

The expected value of this offer is £5.75. If you completed it hundreds or thousands of times, your average profit would be close to this figure. Of course, you’re only completing it once, so variance comes into play. I must stress again; you may make more than this or even a small loss.

If you make a small loss on this offer, don’t be disheartened, as it’s all about the expected value in the long run. You may lose on this offer and make a larger-than-expected profit on the next one. You may even hit the jackpot. Keep this in mind as you work through any casino offer.

A summary of the offer is below:

  • Deposit amount: £10
  • Wagering requirement: £10
  • Recommended game for wagering: Double Bubble (96.02% RTP)
  • Free spins: 30 free spins
  • Eligible game for free spins: Double Bubble (96.02% RTP)

Qualifying wager

First, you’ll need to sign up for a Jackpotjoy account.

Deposit £10 using a debit card. Other deposit methods may not qualify you for the offer. Opt into the offer by selecting ‘Get 30 Free Spins On Double Bubble’ while depositing.


Then go to the game, Double Bubble. For simplicity, you’ll use the same game for your qualifying and free bonus wagering. Later, you can play different games to maximise your ‘Return to Player (RTP)’ for each step.

When wagering to qualify for a reward, such as a bonus or free spins, placing your bets at the minimum stake is best, as this will reduce the variance.

Double Bubble has an RTP of 96.02%. For every £100 wagered, you will average a £96.02 return. In other words, a £3.98 loss. You must wager £10 to qualify for the offer, so expect a qualifying loss of about £0.40.


Claim your bonus

Once you’ve wagered £10, you will see a popup telling you your bonus has been awarded. Click ‘Play free spins’.

Using your free spins

Play through your free spins. Jackpotjoy will credit any winnings as cash. That means you can withdraw them without needing to wager them a certain number of times first.

Your free spins have a value of £0.20 each. With 30 of them to play with, you’ll be wagering a total of £6.00. Double Bubble has an RTP of 96.02%, so you can expect to make £5.76 cash on average.

Take your approximate qualifying loss of £0.40 from this, and you should average £5.36 profit in the long run.

Continue with casino offers

I only offer guides for a couple of casino sign up offers and instead focus on the sports side of betting. However, there are several services where you can get instructions for every casino offer available.

I strongly recommend OddsMonkey. Their clear and thorough guidance covers everything you need for any casino offer. Once you have access, head to ‘Casino’, then ‘Casino Guides’ from their main navigation.
