Kwiff New Customer Bonuses Reviewed
Founded in 2015, Kwiff offers something different to the rest and is now also available on desktop, having initially been launched as a mobile-only bookie. With a new outlook on gambling, but with classic features, there is something for everyone and the offers make it worth trying.
⚽ Sportsbook Bonus
After initially offering a £30 mystery bet, which some punters felt wasn't great, Kwiff decided to improve things by not only removing the mystery element, but also increasing the amount to £40. The point of entry remains the same at just £10, so this is great.
Taking a closer look at the terms, you need to stake £10 at minimum odds of evens (2.0) to qualify for the offer. Once that has been settled, the following free bets (worth £10 each) are credited: 1 Single, 2 Accas & 1 Bet Builder (min. 3 selections each)
There are no wagering requirements, so these are some of the more generous free bets available, but it should be noted that you need to use them within 7 days.
🔢 Our Rating: 9/10
🎰 Casino Bonus
The welcome deal on the casino side of things is definitely more 'common', as Kwiff offers up to 200 free spins with no wagering requirements.
There is a drawback, though, as players will have to wager £20 a day to get 40x £0.10 spins. Getting 200 free spins is possible, but it would take four days and require £100 to be wagered, which is slightly underwhelming.
🔢 Our Rating: 5/10
Kwiff Promo Codes for Existing Customers
Kwiff offers a decent selection of promotions for punters who already have an account on the site. No promo codes are needed for these, it should be noted, as punters just need to follow the terms and conditions to be eligible.
For example, Kwiff makes acca betting a more enjoyable experience with boosted odds and an insurance, which is great stuff.
There is also a weekly rewards promotion, which has a surprise element to it, as well as a couple of promotions for horse racing.
In our eyes, therefore, Kwiff certainly passes the promotions test, and this is good to know for those who cannot claim one of the welcome offers again.
How to Sign Up and Use Bonuses on Kwiff
Registering for an account on Kwiff and claiming a bonus is very simple but if you need assistance, you can follow our step-by-step guide below.
-
Tap on 'Get Started'
We used the Kwiff app to test the process and when you first open it, you will be given two options: ‘Get Started’ or ‘Login’. Tap the former and let’s begin!
-
Set the Account Details
The first thing you will need to do is enter your phone number, which will then be used as the main login. You also need to enter your email address before creating a username and password for your Kwiff account.
-
Enter Your Personal Information
Following this, you will be asked to provide your personal information such as full name and home address. Make sure that the information is correct before tapping on 'Next', as this information is used for the account verification.
-
Set Your Deposit Limits
Kwiff also requests that you set deposit limits on the app as part of the signup process. Punters can set daily, weekly and monthly limits, which is something that we highly recommend to everyone.
-
Place a Qualifying Bet
In order to unlock the surprise bet, you must first place a qualifying bet worth £10+ at a minimum odds of evens (2.00). We added an example to the bet slip in the image below.
The surprise bet will then be credited within 48 hours of placement. Maybe you will get lucky and withdraw winnings from Kwiff a few days later!
Kwiff Payment Methods for Bonuses
Kwiff actually offers a decent number of payment methods and the best part is that all of these can be used when claiming one of the offers.
