Detailed review: Is Kwiff betting legit?

Kwiff is a UK sportsbook with a unique product for sports bettors. Kwiff supercharges bets for players in different scenarios. Supercharge means that Kwiff boosts your winnings or odds remarkably, sometimes by total surprise.

Kwiff holds a valid UK license from the UK Gambling Commission. This means guaranteed safety for players' transactions and tax-free winnings. Kwiss is heavily optimized for mobile and is exceptionally convenient to use on all mobile devices!

Kwiff bet - surprisingly sign-up offer

All new players at Kwiff can get a £20 surprise free bet as a sign-up offer. After placing your first bet with a minimum stake of £10 and minimum odds of 1.50, you will be rewarded with a £20 surprise bet.

Minimum deposit for bonus: £10 Max bonus amount: £20 as a surprise bet Minimum odds to claim the surprise bet: 1.50 Rewards will be credited to the player within 48 hours No wagering requirements Stake excluded from surprise bet winnings Full terms and Bonus terms apply.

Kwiffs algorithm will generate a bet for you that can be on any sport or any league. All winnings are paid without wagering requirements - only the initial stake is excluded. Remember, even the surprise bet can be supercharged!

Short instructions for the bonus:

  • Join Kwiff & create your new account
  • Make your first deposit
  • Place your first min. £10 bet
  • Get a £20 surprise bet that can be supercharged!

There are advantages and disadvantages to this feature. For some (and for me), it can be exciting, with a bet being placed on something I wouldn't typically gamble on, opening up a whole new experience. Conversely, some customers may have no interest in the bet the algorithm places or feel they could have played it more wisely.

Kwiff has an available payout of 85%, significantly less than competing bookmakers. Across all markets, including major sports like horses and football, Kwiff's odds are somewhat less favourable. However, in most sports, Kwiff cleverly counters this by offering an odds boost (which they describe as being 'Kwiffed'). This helps give better odds and adds some excitement to the game also.

When placing a bet on a major sport like football and cricket, Kwiff showed very clearly the original odds, followed by the 'Kwiffed' odds, an automatic odds boost, so I could easily see when Kwiff was offering the better deal. This feature certainly added a new dimension to the betting experience.

In summary, Kwiff doesn't offer the best odds for a regular player who plays several bets daily. Still, for a more entertainment-seeking player looking for a thrilling experience in sports betting, kwiff's odds are excellent.

Several markets are available at Kwiff, where you can find odds for multiple popular sports for UK bettors. Kwiff has covered all the most prominent sports, including football, basketball, tennis, horse racing, snooker, American football, etc.

Kwiff doesn't offer the more niche sports that some other sites give access to. I also couldn't see any e-gaming or virtuals. While this felt a bit disappointing, Kwiff more than made up for it with its varied markets within each game.

You can cash out your bets before they are officially settled. The cashout feature allows you to take your winnings if you have a bad feeling about the game turning around, or you can limit your losses and take out what you still can if things are looking bad.

Kwiff doesn't offer cashout for all bets, but for the most part. Also, any cashout can be supercharged, so even if you take out a slight loss, it may be a winner in the end!

Kwiff offers a lot of live betting odds that are available in the In-play section. Different sports are lined up conveniently where you can find all the matches that are currently going on and ready to bet on. The user interface is straightforward, and live betting has been made very handy. All matches are easy to find, and you can follow the time and score of the games as well. 

Markets update quickly and smoothly, and in-game needs vary, giving you a unique betting experience each time. Kwiff's in-play odds are not as good as other bookmakers, but they might get supercharged at any point, making them better than anywhere else.

Good user rating received Kwiff betting app is available on multiple devices. The app was free and quick to download onto IOS and Android devices. Logging in was hassle-free, and I could see an overview of my betting slip and live games on the home page. Push alerts made keeping up with my live bets easy and more exciting. The graphics were sleek, and navigation of the app was incredibly easy.

Similarly, the mobile site was professionally designed and simple to navigate. All buttons, fonts and lists have been made visually easy for the eyes and easy to scroll and browse.

The selection of payment methods is smaller at Kwiff. You can only make deposits and withdrawals using EcoPayz, Paypal, Visa or Mastercard Debit cards. The minimum deposit amount is £10. To deposit, go to "My Wallet" on your profile and select "Make a Deposit". Kwiff operates a closed-loop payment flow to meet its regulatory obligations. Withdrawals should be returned to the original deposit method used.

You can get customer support in three different ways. Customer support helps you 24/7.

Locating customer support via the desktop site took a lot of work. However, once situated via the FAQs, I noted Kwiff offers email support only and not a phone number. When sending an email, Kwiff responded within 2 hours, which was friendly and quick. Also, Kwiff Twitter account is one slightly more unusual way of searching for and obtaining information.

Kwiff holds a gaming license granted by the UKGC, the UK Gambling Commission. In this case, the permit requires betting sites, Kwiff, to confirm all customer's identities. All players need to verify their accounts by sending the following documents:

  • Photo of your ID, passport or driving license
  • Photo of a recent proof of address, such as a utility bill
  • Proof of Deposit Method

Kwiff takes responsible gambling seriously and offers players multiple tools to keep control of their betting, such as:

  • Daily/Weekly/Monthly Deposit Limits
  • Daily/Weekly/Monthly Loss Limits
  • Reality checks

And as is standard in the industry, Kwiff provides links to the websites of organizations promoting responsible gambling.
