Details of Kwiff sign up offers for 2025
Kwiff has two sports welcome offers to choose from, plus a third offer for their casino section. If you're searching for a sportsbook that provides exciting, unconventional promotions, Kwiff’s sign-up offers are worth considering.

Kwiff Sports Welcome Offer 1: Get a £30 surprise bet
Kwiff’s flagship promotion is the £30 Surprise Bet. When you place a £10 qualifying bet at minimum odds of 1.50 (1/2), you will receive a randomly allocated £30 bet from Kwiff’s algorithm.
This surprise bet can be anything; Kwiff’s algorithm randomly generates it. This is a fun and quirky way to dish out welcome bonuses, which makes Kwiff so unique. The surprise bet can be placed on any market except for each-way bet.
This feature is part of Kwiff’s signature “supercharged” betting experience, where odds and bets can be unexpectedly boosted. If you're looking for a little surprise, this is a nice way to receive a welcome bonus.

Kwiff Sports Welcome Offer 2: Get £30 in free bets
For bettors who prefer more control over their free bets, Kwiff offers an alternative sign-up promotion. Instead of a randomly generated bet, this welcome offer lets you choose how to use your free bets. The £30 in free bets is credited within 48 hours after your qualifying bet settles and is divided as follows:
- £10 Free Bet – Must be placed on football (minimum odds of 2.0).
- £10 Free Bet – Must be placed on horse racing (minimum odds of 2.0).
- £10 Free Acca Bet – Must be placed on an accumulator with at least four selections (minimum odds of 2.0).

Kwiff Casino Welcome offer: Get 200 free spins
If you enjoy online casino games, Kwiff also offers a casino welcome bonus: Wager £20 on slots and receive 200 free spins on Book of Dead. Here are the key details:
- The free spins are credited in batches of 40 over five days
- Spins are valued at £0.10 each
- Maximum withdrawal winnings from free spins: £250
- No playthrough or wagering requirements – winnings are yours to keep
This is a rare and generous casino bonus, as most free spin offers have wagering restrictions. If you’re a slots fan, this could be an exciting bonus to claim.

How to get the Kwiff sign up offer
To activate the Kwiff sign up offer you must first register a new account. You will then need to deposit £10 and place a £10 qualifying at minimum odds of 1/2. This bet can be placed on any sport on any market, except each-way bets. You will receive your £30 surprise bet within 48 hours of your qualifying bet settling.
Step 1 – Activate the Kwiff welcome offer
To activate the Kwiff welcome offer, click on the link above. This will redirect you to the official Kwiff website (www.kwiff.com) where you can begin the registration process.
Step 2 – Complete the registration process
To claim the welcome bonus, you must complete the Kwiff registration form. This process is straightforward. All you need to do is enter the correct details where prompted, such as your full name, address, and date of birth, and create a unique username and password for your account.
To continue, you must link your phone number to the account and enter the four-digit security code. We also suggest opting in to marketing emails so you don’t miss out on any freebies or promotions.

Pro tip: Account verification can take up to 72 hours, so try to plan ahead if you want to bet on a specific event.
Step 3 – Make your first deposit
Now that your account has been registered, the next step is to make your first deposit. This needs to be a minimum of £10 and can be made using any method available on the Kwiff website, as there are no restrictions on payment methods in connection with the welcome offer.
I deposited via debit card and my funds were available instantly. If you have any issues with this process, contact Kwiff’s customer service team straight away.
Step 4 – Place a qualifying bet
With the £10 you have deposited, you must use these funds to place a £10 qualifying bet to claim the Kwiff bonus. The qualifying bet can be placed on any sport and any market except for each-way bets; those do not qualify.
There are major competitions to bet on at Kwiff, including the Premier League, La Liga, and Serie A. You can also bet on popular horse racing meetings, tennis matches, and golf events.
Step 5 – Receiving your £30 free bet
Once your qualifying bet has been settled, you should receive your £30 surprise bet, allocated randomly by Kwiff’s algorithm. You can view your Kwiff free bet under your account's ‘My Bets’ section when logged in.
There are no wagering requirements on any winnings you may receive from the £30 surprise bet – the funds are yours to keep and can be withdrawn.
Intro to Kwiff’s sports betting options
As far as Kwiff’s sports betting options go, there is a way to go. I was a bit disappointed with the sportsbook as only 18 sports (plus e-sports and virtuals) are available to bet on. For an online sports bettign site, this is tame, and I have to say I expected more. A decent amount of competitions and markets are covered within each sport, but if you require more niche sports or a more varied selection, Kwiff isn’t for you.
For football fans, all the main European leagues are available to bet on, including:
- Premier League, Championship, League One, League Two & National League
- Ligue 1, La Liga, Bundesliga, and Serie A

There is also good news for fans of Horse Racing, Golf, Tennis, Cricket, Basketball and American Football as there is a decent selection to browse. Within these sports and competitions, you can expect to find the following markets:
- Match betting
- Handicap betting
- Totals over/under
- Outrights
- Bet Builder
- Each-way
- In-play
The range isn’t tremendous but there is still a semi-decent amount for you to get stuck into, though I would have hoped for more. Kwiff’s odds are in line with some of the big sportsbooks.
For example, Kwiff is offering Arsenal to beat Brighton at 1.30, whereas Bet365 is offering 1.33 (odds correct at the time of writing). Your bet could also get Kwiffed, so you can gain some value on other bookmakers.
Kwiff promotions for existing customers in 2025
Good news if you've already claimed the Kwiff welcome offer – the fun doesn't stop there! Kwiff keeps things interesting with a brilliant range of ongoing promotions that'll keep you coming back. Let me walk you through what's on offer for existing customers.
Kwiff Sports Club
Think of this as your weekly rewards programme. It's nice and straightforward – the more you bet during the week, the more you get back:
- £25 – £49.99 wagered → £5 Surprise Bet
- £50 – £99.99 wagered → £10 Surprise Bet
- £100+ wagered → £20 Surprise Bet
Just remember to opt in each week to take part – it's easy to forget!
Bet Builder Insurance
We've all been there – one team letting down your entire acca. Kwiff feels your pain, which is why they offer this safety net:
- Place a pre-match Bet Builder on football with at least 4 selections.
- The minimum total odds must be 5.00 (4/1).
- If only one selection loses, Kwiff refunds the stake as a £10 free bet.

3+ Fold Acca Shield
Similar to the Bet Builder Insurance, but for standard accumulators:
- Place a pre-match accumulator bet with at least 4 selections.
- Each selection must have minimum odds of 1.50 (1/2).
- The overall accumulator must have minimum combined odds of 5.00 (4/1).
- If only one leg loses, Kwiff refunds the stake as a free bet (up to £20).

Supercharged Bets – “Getting Kwiffed”
This is what makes Kwiff special. Your bets can randomly get “Kwiffed” with supercharged odds after you've placed them. You never know when it'll happen – it's like a little lottery every time you bet. The boosts can be modest (say 2/1 becoming 3/1) or massive (4/1 shooting up to 50/1). It works on singles and multiples across all sports.
- The system does not disclose when a bet will be Supercharged
- If it happens, the new boosted odds are shown instantly
This automated feature applies to single and multiple bets across all sports markets.
Horse Racing Money Back Offer
Here's a neat one for the racing fans:
- Place a bet on selected horse racing events.
- If your selection finishes 2nd to the Starting Price (SP) favourite, you receive a Surprise Bet refund (up to £10).

First Past the Post & Double Result
Two cracking offers for racing enthusiasts:
- If your horse crosses the line first but is later disqualified, Kwiff still pays out as a winner.
- If your selection is awarded first place due to a steward’s decision, Kwiff pays out on both results.
Other offers for existing customers
Keep an eye out for these various limited-time promotions, including:
- eFootball Bet & Get: Place a £20+ bet on eFootball and receive a £10 Surprise Bet.
- Greyhound Racing Promotion: Place three £10 bets and receive a £10 free bet.
- Top 10 Supercharge: The top 10 biggest Supercharged bets of the week receive a £10 Surprise Bet.
Kwiff payment methods: UK options for deposits & withdrawals
You can deposit and withdraw through a variety of methods at Kwiff. When making your first deposit to claim the Kwiff welcome offer, there are no payment method limitations, and your funds should be available instantly.
The tables below detail which methods you can use and any limits they may have, starting with the deposit methods.
Deposit methods, delays, and limitations

Kwiff sign up offer vs the competitors
We have compiled a table to compare the Kwiff welcome bonus against some of the best UK betting sites to see where it stacks up.
Bookmaker | Offer details | Min Deposit | Min Odds | Bonus to stake % |
---|---|---|---|---|
Kwiff | Bet £10, get £30 free bets | £10 | Events (2.0) | 300% |
Bet365 | Bet £10 Get £30 in free bets | £5 | 1/5 | 300% |
William Hill | Bet £10 Get £60 in free bets | £10 | 1/2 | 600% |
Ladbrokes | Bet £5 Get £25 in free bets | £5 | 1/2 | 500% |
Betfred | Bet £10 Get £50 in free bets | £5 | Evens (2.0) | 500% |
Coral | Bet £10 Get £40 in free bets | £5 | 1/2 | 400% |
The Kwiff sign up offer doesn’t come close to some of the best offers around, although it matches Bet365’s offer in terms of value. Kwiff is a new name in the online gambling world, and it can be hard to compete against the big dogs like William Hill, Betfred, and Ladbrokes regarding the value they provide.
Kwiff, however, brings more value to the table because it is a unique brand and any bet can be supercharged. It’s good to have something that the top bookmakers don’t, but it may take a while before Kwiff’s welcome offer can compete with the best of the best.
Recent news with Kwiff and the UK gambling industry

Summarising my Kwiff sign up experience
To recap, Kwiff’s welcome offers stand out in the sports betting market, giving new customers the choice between a £30 Surprise Bet—where the selection is randomly generated—or £30 in Free Bets, which provides more flexibility across football, horse racing, and accumulator markets.
The bonus is straightforward to claim, and both offers require only a £10 qualifying bet, making them accessible for casual bettors. I particularly appreciated the lack of wagering requirements on winnings from these free bets.
Kwiff provides a solid welcome package with the unique selling point of potentially supercharged odds for those considering signing up. Though it may not match the raw value of offers from William Hill or Betfred, it's worth adding to your betting rotation.
