Kwiff Review 2025: Unique Bookmaker With Random Boosts

Gambling.com Rating: 8.7/10

Our Verdict: Kwiff offers a unique betting experience with randomised odds boosts, enhanced cash outs, and other inventive promotions.

Quick Summary: Kwiff at a Glance

Kwiff doesn’t just rely on standard odds and offers. This betting site stands out from the crowd with unique promos like random odds boosts, surprise free bets, and randomly enhanced cash outs.

The betting app is one of the best I've used, while the desktop site recently got a visual refresh that now matches the slick mobile feel.

Odds are generally solid, offers are plentiful, and the site is easy to navigate - even if you're new to online betting.

I'd like to see the bet builder rolled out to more sports, while I'd also like if live streams were more widely available.

However, Kwiff makes up for those couple of shortfalls with its impressive range of creative promotions and loyalty rewards.

Kwiff’s Welcome Offer vs Offers From Competitors

When I signed up and placed my first £10 qualifying bet, I quickly received £30 in free bets, delivered in three £10 tokens. They are split as follows:

• One £10 football bet
• One £10 horse racing bet
• One £10 accumulator with a minimum of four selections

There are no hidden terms or confusing steps and the value matches up to the equivalent offer from bet365, although bet365's offer allows you to use the free bets on any markets you like.

Still, this is a good bet £10 get £30 deal that is well worth claiming and allows you to try out a few different types of bets with minimal outlay.

Here's how it compares to other welcome offers from UK bookmakers:

Top 5 Kwiff Offers for Existing Customers

It's tricky to choose my top five Kwiff promotions, because there are around 10 offers that provide genuine value.

Aside from the offers outlined below, there are also loyalty clubs with free bet rewards for weekly betting and money-back specials for certain scenarios (like if your horse is beaten by the starting price favourite).

I only consider a bookmaker to be top-tier if it offers lots of existing customer promos. Kwiff definitely delivers in this regard.

Kwiff Horse Racing Betting

I’ve used Kwiff to bet on flat and jumps racing alike, and the odds tend to align pretty well with most mainstream bookies.

Live racing streams are available for some racecourses, while there are also extra each-way place offers on selected races.

One notable omission is best odds guaranteed, which you’ll find at some of the best horse racing betting sites like Coral and Ladbrokes.

It's worth calling out the '2nd to the Favourite' promotion again here: If your horse finishes second to the SP favourite at a selected meeting, you’ll receive a free bet up to £10.

The 'First Past The Post' promo also pays you out as a winner if your horse finishes first and is later demoted after a stewards enquiry.

All in all, the range of racing promos and features makes this a great bookie for betting on horses.

Kwiff Football Betting

Football is another of this site's strong suits. Again, it's the range of promotions that stands out.

Kwiff has an acca insurance offer which gave me a free bet refund when one leg of my accumulator let my bet down.

A similar offer applies to bet builders, so when I 'hit the crossbar' on a same-game acca, I got refunded as well.

The bet builder offer comes with a £10 refund, while there's a maximum of £20 for the acca offer.

When you add boosts and supercharged cash outs into the mix, Kwiff becomes an option worth considering for football bets.

However, if I'm going to rate Kwiff as one of the very best football bookmakers, I'd like to see football live streams and early payout offers made available.

Kwiff Cricket Betting

Kwiff covers all the cricket I’d expect - Tests, ODIs, T20 internationals, and domestic tournaments like the IPL and The Hundred.

Market range is respectable, with odds on markets like top team batsman, total runs, and methods of dismissal all included.

I placed bets in-play on an England v India test match and found the live centre was pretty impressive.

A 2-D graphic showed me ball-by-ball action and I was able to bet on the outcome of the next delivery with instant live markets.

However, if you want to watch cricket streams while you bet, you'll need to consider a bookmaker like Unibet or bet365. 

Kwiff Tennis Betting

I bet on Wimbledon using Kwiff and had a good experience. The main pre-match markets (winner, set betting, total games) were available across ATP, WTA and Grand Slam events.

During matches, live stats like serve percentages and break point conversions appear in the event view, along with real-time scoreboards.

There’s no live tennis streaming, but in-play betting worked well for me.

Tennis isn’t Kwiff’s best sport, but this is still a functional tennis betting site.

Kwiff Golf Betting

I placed a few each-way outrights during The Masters and the US Open using Kwiff.

Each-way terms were typically 1/5 odds for five places - pretty standard, although the best golf betting sites pay out more places.

The top golf bookies also have a greater range of markets than Kwiff, and release their odds earlier.

But for casual golf betting, Kwiff does a decent job. And any bet you place - even long-range 100/1 outsiders - can get supercharged, which is always part of the appeal.

Kwiff Odds & Market Variety

Kwiff offers competitive odds across most sports. I compared a few events and found pricing close to rivals like Bet UK and Virgin Bet.

• Premier League: Over 2.5 goals often priced at 4/5, similar to Ladbrokes
• Tennis: Match winner odds were in line with QuinnBet
• Horse Racing: Competitive win odds and each-way terms, though no best odds guaranteed

For football, marquee fixtures often had over 100-pre-match markets. Lower league games typically came with 40–50 options.

Outside of football, I found that Kwiff sometimes lacked a wide range of markets.

While sports like tennis and cricket come with a good selection, other sports like rugby and golf don't get the full treatment.

For example, I checked a rugby match between the Lions and Australia - William Hill had 19 pre-game markets to bet on, while Kwiff had just six.

Kwiff Bet Builder

Kwiff’s bet builder is only available on football and supports up to eight selections from common markets.

The bet builder insurance offer is the best thing about the same-game acca here, but there are a few areas for improvement.

I'd like if bet builders could be placed on more sports. For comparison, Bzeebet's same-game acca works for 10 sports, while bet365 leads the way with 14.

Also, not every football game comes with the bet builder option. Big games like Premier League or Champions League matches do, but some lower-tier football matches don't.

If the bet builder is available, you'll see a white 'BB' icon next to the match odds.

Live In-Play Betting at Kwiff

Kwiff’s in-play betting service does a solid job.

Most sports come with an array of in-play betting options, and although live streams aren't widespread, live updates and graphics are user-friendly.

Horse racing is streamed live, although it's limited to selected races. This isn't one of those sites where you watch every major race from the UK live unfortunately.

But the supercharged cash out feature is the big positive when betting in-play here.

I had £5 on Liverpool to win 2–1 at 10/1 (potential return: £55). With 10 minutes left and the score at 2–1, the standard cash out offer was £38.50.

When I cashed out, Kwiff boosted it to £45, a surprise 17% uplift on the value I took.

I've not seen this offer available with any other betting site, so full marks to Kwiff for getting creative here.

User Experience & Site Design

Kwiff recently updated its desktop layout, bringing it in line with the app.

The dark purple and black colour scheme gives the site a unique look and the overall design is pretty clean, if a tad busy at times.

Navigation is intuitive:

• Main sports are pinned at the top of the home screen
• The promotions tab is accessible from both mobile and desktop menus
• A 'Trending Bets' section updates you on the most popular bets with other users
• A banner tells you when other punters have had their odds boosted ('Kwiffed')

I like that the bet slip is always accessible at the bottom of the screen without being intrusive. Switching between singles and accas is easy .

Compared to older versions of the site, this new layout is a big upgrade. My one gripe is that the desktop site takes a bit longer to load than the mobile version.

Depositing & Withdrawing Funds

Kwiff Betting App

Kwiff has one of the best betting apps I've used.

I downloaded it on Android and mainly tested it on that platform, but iOS users get a similar experience

It’s rated 4.2/5 stars by users on Google Play and 4.6/5 on the App Store, which matches my experience: fast, reliable, and glitch-free.

Key features include:

• Fingerprint login and Face ID
• Push notifications for free bets and boosts
• Easy bet slip access and fast navigation

Bet placement takes seconds, and the visual confirmation when your bet gets 'Kwiffed' is a nice touch.
