Welcome Offer Details

Kwiff’s sign-up offer is generous compared to some of their competitors, and with the free bets offer not having any wagering requirements, they’re likely to draw in a considerable amount of new customers.

The Sportsbook offer will be popular as with the promise of a surprise £20 free bet with enhanced odds, the potential returns on that free bet could be sizeable.

The qualifying bet can be placed on any sporting event, and as long as the wagering requirements on that qualifying bet are met, then the new customer will be eligible for the free bet from kwiff.

An example of this could be if a new customer decided to place their £10 qualifying bet on Ajax to beat Borussia Dortmund in the Champions League on 19th October at odds of 2.10.

This would qualify the punter for the surprise £20 free bet, which kwiff would place for them with enhanced odds.

If that surprise free bet is to win, then customers will be able to withdraw their winnings into their personal bank account, which is a real plus, because some other bookmakers will require the punter to wager those winnings numerous times before making a withdrawal.

The slots offer is another generous one, although it’s important to read through the Terms and Conditions to make sure that you meet the requirements of that sign-up offer.

All you have to do is wager £20 in their slots games for five consecutive days, and they can earn up to 200 free spins on Book of Dead. They can earn 40 free spins a day if they don’t meet the wagering requirements on one day though.

With any winnings from the 200 free spins being eligible to be withdrawn into the customer’s personal bank account straight away, it’s another real plus compared to some of their competitors.

How to use the promo code

To get the £20 in free bets from kwiff, new customers can follow these simple steps during the registration process.

  1. Click here to join kwiff.
  2. Then click the ‘register’ button.
  3. Fill in all the information such as username, password and verification and create your account.
  4. Once you have created your kwiff account, deposit £10.
  5. Place a £10 bet at odds of 1/2 (1.5) or greater.
  6. You will then be rewarded with a £20 free bet. This offer is specific to kwiff.

Kwiff only requires new customers to deposit and bet £10 on odds greater than ½ (1.5) on their sportsbook.

There are a number of different sporting events that punters can choose to place their qualifying bet on, with the bookmaker offering markets on football, tennis, and horse racing to name a few. Once you have placed the qualifying bet, the £20 in free bets will be credited to the customer’s kwiff account.

These free bets don’t have to be wagered either, so if a punter was to win from a free bet, then they could just withdraw the funds into their personal bank account straight away if they wished to do so.

Betting Tips

Our betting tip for kwiff for this week comes from the Premier League, as we predict that Leeds United will run out winners against struggling Norwich City.

The Yorkshire-based side are currently sat 17th in the top-flight standings, and will be keen to put some distance between themselves and some of the relegation-threatened teams.

Marcelo Bielsa’s side picked up a hard-fought point in their most recent fixture against Wolves, where a late Rodrigo penalty rescued a point in a 1-1 draw.

Norwich City are without a win in their last eight matches in all competitions and were thrashed 7-0 by Chelsea in their most recent fixture, and so confidence won’t be anywhere near a good level.

That means that Daniel Farke’s side remain rooted to the bottom of the table, and are already five points adrift of safety, with their survival chances looking bleak.

Leeds should have too much quality for the Canaries at Carrow Road, so we’re tipping a Leeds United win in this one, as they look to pick up much-needed points to kickstart this year’s campaign.

Betting Tip – Leeds United to beat Norwich City @ 49/50.

What is Kwiff Bet Boost?

Kwiff offers customers enhanced odds in their Bet Boost, where a single, or accumulator bet could be ‘supercharged’ to bigger odds than what kwiff were originally offering.

There aren’t any restrictions or Terms and Conditions that punters have to meet to be eligible for the kwiff Bet Boost, with them being the only bookmaker to offer a boost in odds on any event across the globe, regardless of what type of bet is being placed.

Kwiff Refer a Friend

Kwiff offer a generous offer to their existing customers, with their ‘Refer a Friend’ scheme.

The bookmaker offers a £10 ‘surprise’ free bet to new and existing customers after their new customer has signed up with kwiff.

All the existing customer has to do, is follow these simple steps:

  1. You share your unique referral link with a friend (you’ll get that link in the kwiff app by going to your Profile page and then tapping ‘Refer a Friend’).
  2. Your friend downloads kwiff via that link and places their first bet.
  3. Kwiff make a £10 bet on behalf of both of you, adding the bets to your accounts.


The kwiff new customer offer is a generous bonus for punters wanting to test out the bookmaker. There are a considerable range of markets to bet on in their Sportsbook. With kwiff also offering 100 free spins, that’s another real plus for the bookmaker when it comes to wanting to attract new customers to their site.

With no wagering requirements needed to withdraw funds into a personal bank account involved in the sign-up offer as well, you would imagine that this will prove popular with new customers.

The only slight negative with the surprise £20 free bet is that customers don’t have any input in the selections on the bet, which is something that might put punters off, as the surprise bet might include selections that they wouldn’t choose themselves.
