Kwiff Welcome bonus

Kwiff has a separate Sports and Casino welcome offer which really maximises value to the punter. As long as you place one single £10 bet on any market at odds greater than 1.5, you will be credited with a £20 'surprise' (free) bet.

This welcome offer is for UK/IRL customers on mobile only, and you can only place one qualifying bet per person and IP address.

What is a Surprise Bet?

Surprise Bets are a totally unique feature of Kwiff, generated by a random algorithm. They can be for any sport and can be any type of bet. Winnings from Surprise Bets are paid out in cash, excluding the stake.

Basically, it is a free bet chosen for you by the Kwiff gods.

Why the Kwiff sign up bonus is good

  • The £20 Surprise Bet is not subject to any wagering requirements
  • You can withdraw all the winnings as cash (excluding the stake) from the Surprise Bet
  • IT IS POSSIBLE that the odds on your Surprise Bet could be Supercharged (aka boosted).

Who the sign up bonus is good for

The welcome offer is good for everyone who likes surprises and who is eager to bet on multiple sports and markets. It is also good for mobile and app customers, as the sign up and overall betting experience has been optimised for mobile.

If you like betting and trust the process, then Kwiff Surprise Bets are definitely for you!

Who the sign up bonus is not suitable for

If you want to be able to choose how to use your free bet, then the Surprise Bet might not be a sweet one for you. If you want to build a bet and watch it play out after you have signed up, Kwiff do not have a bet builder feature or any live streaming, which is a real shame.

Customers who deposit with an eWallet (Skrill/Boku/Neteller/PayPal) do not qualify for this offer.

  • You cannot use this offer in conjunction with any other Kwiff promotion

Author's opinion: Yay or Nay?
Poppy Taylor

Poppy Taylor

Yay: As someone who loves a sweet (or a salty) surprise, I think this is a brilliant sign up bonus. Would I necessarily bet on Ice Hockey? No. But if a surprise bet gives me unbeatable odds and great potential winnings, then yes I would!

Nay: There's not much nay to say, except there is an overall small range of markets on which to place your initial bet. However, all the key ones are there! I would not want to stake £10 on futsal to qualify anyway.

1a) Kwiffed Odds

When you see this phrase read; enhanced odds on steroids!

Essentially, Kwiff uses a randomised algorithm on all winning bets which sees some get their odds 'supercharged’ (aka ‘Kwiffed’). Not every bet will be Kwiffed, but every bet can be - which is what adds to the excitement of it all.

The largest ever boost recorded on Kwiff was 2000 times the original odds offered.

After speaking to some lucky bastards who had been Kwiffed, however, they reported an average of less than 1 out of every 5 bets which some might say is on the lower side of a reward. BUT when you see how supercharged certain bets can be and have been, it is clear Kwiff are going for quality over quantity.

Example of Kwiffed Odds

1b) Supercharged Cash Out

Working very much like Kwiffed odds, supercharged cash out adds extra funds to your minimum total cash out amount meaning you have the chance to double your cash or even more. You can take advantage of both of these supercharged options after you have signed up to Kwiff and claimed their welcome offer.

As is the way with Kwiffed Odds, not every cash out will be supercharged, but every cash out can be.

I have not been able to determine the frequency of supercharged cash out (yet), but it definitely exists and also uses an algorithm to randomise super charging!

2) Refer a Friend Scheme

PayPal, Revolut and now… Kwiff? Referring a friend is a great way to build a trusted network around your company and it is a testament to how upright Kwiff are.

When you share your personal referral link (found in your account on the Kwiff app) and your friend downloads the Kwiff app and places their first bet, Kwiff give a £10 surprise bet to each of you and, as are the rules, you get to keep the profits if the bet wins.

The bet is the same for both you and your friend (as all is fair in Kwiff and war) but one (or both) of your bets could get Kwiffed or Supercharged!

This is a great incentive to become a member and share the love 💜

Authors Note

Important: you cannot refer yourself for the refer a friend scheme. This might seem obvious, but the snakey people out there might think Kwiff have drawn themselves a loophole. Kwiff WILL be able to know if you are both the referee and the referred. One person, one IP address, one £10 surprise bet upon referral. No Kwiff, no buts, no coconuts.

3) Kwiff Sport Club

Trying not to dive completely off the beaten track, Kwiff does have some familiar features of a more traditional sportsbook. The Kwiff Sports Club works as shown in the image below..

This promotion is valid to both new and existing customers!

Minimum odds of 1.5 apply to each bet. I don’t like that this excludes weekend betting, however I do like that there is a balance between free (surprise) and cash bets.

4) Kwiff Acca Shield

Kwiff’s Acca shield, more popularly known as acca insurance, will refund your stake back as a surprise bet up to £/€20 if one of your selections loses when you stake £/€5 or more on an acca with 4 or more legs. This offer, on the surface, is better than Betfred’s acca insurance - which is only a £/€10 refund for an acca with 5 legs or more, as both have the same minimum odds requirement of 1.5 per leg. Furthermore, my odds could get Kwiffed which could be tenfold better than other acca insurances.

⚽ Kwiff or BetFred for Acca Schemes?

Both claim to protect but which one is best?

Kwiff’s Acca shield can only be activated once per week. BetFred just has a maximum return of £10 per day. (So I could do it 7 days a week)

Kwiff refunds up to £20 in… you guessed it, a SURPRISE bet. No surprises there 😉. Betfred, however, refunds up to £10 in cash, and has no minimum wagering requiements (Kwiff is £/€5).

If you are looking for cash but are happy with a smaller amount, pick Betfred. If you are happy with a free bet and love the thrill of supercharged cahs out and surprises, pick Kwiff.

Casino on Kwiff

The casino on Kwiff is slick and has a range of online, live casino and table games, especially for blackjack and roulette. They also offer scratch cards and slots, but don't offer any additional features like a live running total of winnings or any game info before logging in.

Kwiff have a separate Casino Welcome Offer with exclusive slots for Book of Dead

Although the free spins are awarded immediately and any winnings from them are returned to you in cash I don't want to play Book of Dead 😵‍💫

Kwiff sign up bonus verdict


Kwiff HAVE to lose a point and a half for their small range of markets and lack of bet builders, but they seriously make up for this in every other way. Surprise bets, refer a friend schemes and simple, straightforward betting. Dare I say, I recommend getting Kwiffy with it?
