Greatslots opens with a welcome package worth up to €10,000 and 500 free spins spread across your first five deposits. We built it this way for players in the UK who want more than a single match on day one. Greatslots pays out over five separate deposits, not one, so the value follows you through your first fortnight with us. T&Cs apply. 18+. New customers only. Please gamble responsibly (BeGambleAware.org).
What Sets Greatslots Apart
Greatslots runs a casino and a sportsbook side by side, so you never need a second account for football or tennis. Our welcome package pays out across five deposits instead of one. Free spins scale with what you actually deposit, rather than arriving as a flat batch regardless of stake.
You'll find over 10,000 games under one roof, from slots to live tables, crash games and game shows. We're licensed through Brightsky Limited under the Government of the Autonomous Island of Anjouan, Union of Comoros. Every deposit you make is handled by a payment processor registered in Cyprus, which sits behind the scenes of your cashier.

Opening Your Account With Us
Setting up your account with Greatslots takes four steps before your first spin.
- Register at Greatslots — open your account through Register at Greatslots with an email address and a password.
- Activate your bonus — visit the cashier and switch on the offer before each qualifying deposit. Bonuses don't need to be activated in order.
- Make your first deposit — €20 unlocks your first deposit bonus and starts the countdown on its terms.
- Play under the Bonus Games tab — wagering only counts on titles listed there, so check it before you spin.
Building Your Welcome Package — Five Deposits Rewarded
Greatslots spreads its welcome offer over five deposits instead of loading it all into one. Every tier carries its own match, its own free spins, and the same 20x wagering on deposit plus bonus.
| Offer | Value | Wagering | Min Deposit | Valid For |
|---|---|---|---|---|
| First Deposit | 200% up to €2,000 + 200 spins | 20x | €20 | 7 days |
| Second Deposit | 100% up to €2,000 + 100 spins | 20x | €20 | 7 days |
| Third Deposit | 50% up to €2,000 + 50 spins | 20x | €20 | 7 days |
| Fourth Deposit | 50% up to €2,000 + 50 spins | 20x | €20 | 7 days |
| Fifth Deposit | 100% up to €2,000 + 100 spins | 20x | €20 | 7 days |
Your First Deposit Reward
Greatslots matches your first deposit at 200%, up to €2,000 cash, once you put in €20 or more. You'll also collect up to 200 free spins on Sunny Coin 10000, credited at two spins for every euro deposited. The cash side carries a 20x wagering requirement on deposit plus bonus, clearable in 7 days with a €5 max bet.
Your Second Deposit Reward
Your second deposit is matched at 100%, up to €2,000 cash, with up to 100 free spins on Book of Dead at one spin per euro deposited. The same 20x wagering and 7-day window apply, and winnings from the free spins land as cash with no extra wagering.
Third and Fourth Deposit Rewards
Both your third and fourth deposits earn a 50% match up to €2,000 cash. The third pays up to 50 spins on Legacy of Dead, the fourth up to 50 spins on 3x5 Double Blazing, each at one spin per €2 deposited. Wagering and expiry stay the same throughout.
Your Fifth Deposit Reward
Your fifth deposit closes the package with another 100% match up to €2,000 cash and up to 100 spins on Book of Dead. Your maximum cashout from any single bonus is €5,000, and a bet above €5 while a bonus is live can void it.
Weekly Cashback That Follows You
Beyond the welcome package, we run a weekly cashback of 10% on net losses from eligible slots, capped at €5,000 a week. It covers Thursday 10:00 UTC through the following Thursday, credits by 17:00 UTC, and needs claiming within 7 days or it lapses. Table, live and jackpot games sit outside it, and an overall net win for the week rules it out entirely.
Playing Across Our Game Library
Greatslots carries over 10,000 games across slots, live casino, table games, game shows and crash titles. Every category runs on the same account and wallet, so switching between them costs you nothing but a click.
Slots and New Releases
Slots make up the bulk of our library, spanning Megaways formats, bonus buy titles and regular new releases. Each game states its own return to player and volatility on its information screen, and a win is calculated against the paylines or ways it lists there, multiplied by your stake per line.
Live Casino Tables
Our live casino streams blackjack, roulette and baccarat with real dealers, sitting inside the same lobby as our slots. You'll play at whatever stake the table allows, with results decided by the physical shuffle or wheel rather than a random number generator.
Crash and Instant Games
Crash and instant titles sit under their own tab for quick rounds without waiting for a reel to spin. Volatility here runs high by design, since a crash multiplier can cash out at any second before it resets.
How a Win Is Worked Out
Every slot pays according to the symbols landing on an active payline or way, then multiplies that combination by your stake. Higher volatility titles pay less often but bigger when they do, while lower volatility games spread smaller wins more evenly across your session.
Betting on Sport Alongside Casino
Greatslots runs a sportsbook next to its casino, so you bet on football, tennis and more from the same account you use for slots. There's no separate registration and no second wallet to manage, which keeps your balance in one place whichever product you open.
Software Partners Behind the Games
Our library draws on ten providers, and you'll recognise a handful straight away. We work with the following, among others.
- Betsoft — known for cinematic slot design.
- Gamzix — fast, mobile-first slot releases.
- Endorphina — a steady stream of new titles.
- Galaxsys — the studio behind several crash formats.
Every title in our library comes from a certified studio before it reaches your account.
Enjoying Greatslots on Any Device — Wherever You Log In
Browser play works across desktop and laptop without any download, so your account is ready the moment you sign in. Built for touch screens too, our slots and live tables resize to fit a phone or tablet without losing any buttons off the edge.
No app required on either iOS or Android, since everything runs through your mobile browser instead. Bonus tracking follows you between devices, so a session started on your phone picks up exactly where you left it on a laptop.
Keeping Your Money and Data Safe — Our Security Layers
Greatslots holds a licence issued under the Government of the Autonomous Island of Anjouan, Union of Comoros, through Brightsky Limited. Your deposits and withdrawals are processed by Softgate Group Limited, a payment company registered in Cyprus, which sits between your bank and your cashier.
- Licensing — an active gambling licence under Anjouan.
- Age checks — accounts restricted to players 18 or over.
- Bonus caps — a €5,000 maximum cashout limits exposure on any one offer.
- Bet limits — a €5 max stake while a bonus is active protects the terms on both sides.
- Fraud checks — we can withhold winnings where multiple accounts or abuse are found.
If gambling ever stops feeling like fun, the National Gambling Helpline is free on 0808 8020 133.

Staying in Control With Greatslots
Greatslots is for players aged 18 and over, and we'd rather you play within limits than push past them. Gambling works best as entertainment, not as a way to fix a bad week.
If you'd like to step back, GamStop lets you self-exclude across every licensed site for free. GamCare and the National Gambling Helpline on 0808 8020 133 are free and open around the clock. BeGambleAware offers confidential support if a session starts to feel less like fun. Gordon Moody provides treatment for anyone who needs more structured help. If you share a device with someone under 18, tools like Net Nanny or Qustodio, alongside BetBlocker, help keep gambling sites off it entirely.
