OnlySpins Casino UK

I deposited £20 with a Visa debit card on a Tuesday evening, and the 50 free spins were in my account before I closed the cashier window. That session at OnlySpins casino started three weeks of testing. I claimed five bonuses, placed bets on the sportsbook and requested four withdrawals.

OnlySpins online casino holds a UK Gambling Commission licence, runs in pounds sterling and puts slots at the centre of its library, with live dealer tables and a sportsbook behind them. The welcome offer is a 100% match up to £150 plus 50 free spins, with 10x wagering on the bonus.

Bonuses at OnlySpins Casino

Five bonuses ran during my three weeks: a welcome offer, ten no-deposit spins, a Thursday reload, Monday cashback and an invite-only VIP club. I claimed the first four and kept notes on the terms.

Welcome Bonus

A first deposit of £20 or more earns a 100% match up to £150 and 50 free spins on Book of Dead at 10p a spin. I deposited £100 and received £100 in bonus funds, which gave me £200 to play with. I had the spins within a minute of the deposit clearing.

• Offer: 100% match up to £150 plus 50 free spins
• Wagering: 10x the bonus amount, and 10x on free spin winnings
• Expiry: 14 days from activation
• Maximum bet with bonus funds: £5 per spin
• Game contribution: slots 100%, live casino and table games 10%
• Eligibility: new UK customers aged 18 or over

A £100 bonus at 10x means £1,000 in total bets before you can withdraw bonus winnings. At £1 a spin on slots, that is 1,000 spins, and I cleared it across four sessions in six days. The £150 cap is lower than the £200 and £250 matches at some rivals, and the free spins apply to Book of Dead only, so you cannot move them to a slot you prefer.

No Deposit Bonus

Add a debit card and verify your ID, and OnlySpins credits 10 free spins on Starburst with no deposit. My ten spins returned £2.40, so I had to wager £24 before I could withdraw a penny of it.

• Offer: 10 free spins on Starburst
• Maximum cash-out: £25
• Wagering: 10x on winnings
• Expiry: 3 days
• Eligibility: new customers after card and ID verification

Reload Bonus

On Thursdays OnlySpins matches 50% of a deposit of £20 or more, up to £100. I put in £40 and received £20, which carried 10x wagering and a seven-day expiry. The £5 maximum bet applies here as well.

• Offer: 50% reload on Thursdays
• Maximum bonus: £100
• Wagering: 10x
• Eligibility: all existing customers

Cashback Bonus

OnlySpins returns 10% of your net slot losses from the previous Monday to Sunday, up to £50, as cash with no wagering. My net loss that week was £62, and the £6.20 arrived at 2:10pm on Tuesday. Losses on bonus funds do not count.

• Offer: 10% of net weekly losses
• Maximum: £50 per week
• Wagering: none
• Eligibility: any customer who deposited that week

VIP Club

OnlySpins runs an invite-only VIP club with a named account manager, higher withdrawal limits and birthday bonuses. After three weeks and around £600 of deposits I had no invitation, so treat the club as a long-term prospect. The casino runs affordability and safer gambling checks before it upgrades anyone.

• Benefits: account manager, higher withdrawal limits, birthday bonus
• Requirements: invitation after sustained play and passing affordability checks

Read the terms for each offer before you opt in. You must be 18 or over, and bonus terms apply.

OnlySpins Casino on Mobile

OnlySpins has no standalone app for iOS or Android. The OnlySpins online casino UK site runs in Safari or Chrome and covers slots, live casino, the sportsbook and the cashier. I used it on an iPhone 14 for most of a week, and the lobby loaded in about four seconds on 4G.

Accessing the Mobile Site

1. Open your browser: Launch Safari, Chrome or Firefox.

2. Go to the OnlySpins site: Type the address into the bar and bookmark it.

3. Add it to your Home Screen: On iPhone, tap the Share icon and choose Add to Home Screen. On Android, open the browser menu and choose Add to Home screen. You get an icon that opens the site full screen, which is the closest you will get to an app.

Registering on Your Phone

Joining from a phone took me about six minutes.

1. Tap Join Now at the top right of the homepage.

2. Enter your email, a password and your mobile number.

3. Add your name, date of birth and home postcode. OnlySpins checks these against the GamStop register and public identity databases.

4. Upload a photo of your passport or driving licence if the site asks. My passport cleared in 12 minutes.

Gaming Experience on Mobile

Slots run in portrait mode, and live roulette works best in landscape. Lightning Roulette streamed without a stutter on home Wi-Fi, but on 4G the video dropped to a lower quality twice in one hour. Without an app you get no fingerprint login, so you type your password each session unless your browser saves it.

Support on Mobile

The live chat button sits at the bottom right of every page. A deposit question got an answer in under two minutes. A question about bonus eligibility took eleven minutes, which was the slowest response of my testing.

Mobile Verdict

No app means no push notifications and no biometric login. In return you skip a download and get the same library as on desktop. I would not miss the app.

Promotions and Seasonal Offers

Beyond the welcome package, OnlySpins runs a rotating calendar of smaller promotions. I tracked four over the three weeks.

Saturday Spins and Prize Drops

Deposit £20 or more on a Saturday and you receive 20 free spins on Rainbow Riches at 10p a spin. Winnings carry 10x wagering and expire after three days. Prize Drops run on selected Pragmatic Play slots as part of the studio's Drops & Wins network, with cash prizes from £5 to £500 and no wagering. I landed a £10 drop in my fourth session.

• Saturday Spins: 20 free spins on a £20 deposit, 10x on winnings, 3-day expiry
• Prize Drops: random cash prizes from £5 to £500 on selected slots, no wagering

Seasonal and Special Offers

Seasonal offers follow the UK calendar. During the Cheltenham Festival, a £10 bet on any race earned a £10 free bet, with the stake not returned. In December, OnlySpins opens an advent calendar with one prize behind each door.

• Cheltenham Festival free bet: £10 bet, £10 free bet, valid for 7 days
• Advent calendar: free spins, bonus cash and prize drops across 24 days

Check the OnlySpins casino promotions page for current dates, because the calendar changes.

Loyalty Points

You earn 1 point for each £5 wagered on slots, and 100 points convert to £1 in bonus cash with no wagering. That returns about 0.2% of your turnover, so treat it as a small extra rather than a reason to play.

Bonus Terms and Conditions (Overview)

• Wagering requirements: 10x on bonus funds and on free spin winnings. Cashback and prize drops carry none.
• Validity: between 3 and 14 days, depending on the offer.
• Game restrictions: slots contribute 100%, live and table games 10%, and bonus buy features do not count.
• One bonus at a time: OnlySpins settles an active bonus before it activates the next one.

The full Terms & Conditions list the exclusions for each promotion, and I recommend reading them before you tick the opt-in box.
