The lobby at a glance
Westio launched in 2026 with a library of more than 5,000 games, and slots make up the bulk of it: 3,500+ titles from 80+ studios. The lobby is split into categories you can filter by studio, feature and theme, with a search bar for when you already know the name of the game.
Everything runs in the browser on desktop, iOS and Android, so there is no download. On mobile you can add the site to your home screen for one-tap access. Before your first spin, UK rules require your age and identity to be verified, and that includes demo play.

Featured studios
The 80+ studios range from the biggest names to small specialist teams. Here are the ones you will meet most often.
+70Pragmatic Play
The largest presence in the Westio lobby. Expect the Sugar Rush and Sweet Bonanza families (Sugar Rush 1000, Sweet Bonanza 2500, Sugar Rush Super Scatter, Sweet Rush Bonanza), the fishing favourite Big Bass Splash, Fortune of Olympus and the fruit-themed FRKN Bananas. Pragmatic also runs several of the live shows.
Hacksaw Gaming
Known for sharp art and high-volatility maths. Le Zeus is the headline title here, a cartoonish take on Greek myth that suits players who accept long dry spells in exchange for big multipliers.
Nolimit City
The studio for extreme volatility and dark themes. Mental 2 is the one to know, and it is not for small bankrolls or nervous players.
Novomatic
The classic land-based maker. Book of Ra is the original “book” slot that launched a whole genre, with simple expanding symbols and free games.
Other studios
You will also find Betsoft, Evoplay, Platipus, Mascot Gaming, Gamzix, Spribe (Aviator), Onlyplay, PG Games, Peter & Sons, Fantasma, ELA Games and 1spin4win, plus the dedicated live-dealer studios.
Top picks
Our shortlist of the Westio slots worth trying first, from modern cluster pays to old-school reels.
Sugar Rush 1000 and Sweet Bonanza 2500 are souped-up versions of two Pragmatic hits, with higher maximum wins. Book of Ra is the gentle classic, while Fury of Anubis, Crack the Piggy Bank Express and Lucky Penny Power Scatter add collect-style and scatter features.

Fury of AnubisBig Bass Splash remains a steady favourite thanks to its fisherman free spins. Coin Blitz 2, 3 Pyramids of Gold Hold & Win and 4 Clover Pots lean on coin-collect mechanics, while Cyberheist City and Jelly Express bring something different visually.
Live casino & game shows
The Westio live section streams real dealers and hosted shows in HD.
Mega Roulette, German Roulette and Gates of Olympus Roulette cover the wheel, Speed Baccarat 2 suits fast card play, and Mega Ball, Funky Time, Money Time and Sweet Bonanza CandyLand are entertainment-first game shows. Remember that live games contribute only 10% to bonus wagering.
RTP & volatility explained
RTP (return to player) is the long-run percentage of stakes a game pays back across millions of spins. It tells you nothing about a single session. Many studios release several RTP versions of the same game, so check the in-game info panel for the RTP version you are actually playing.
Volatility describes how wins are spread: low-volatility games pay small amounts often, high-volatility games pay rarely but bigger.
| Title | Studio | Volatility (general label) |
|---|---|---|
| Book of Ra | Novomatic | Medium–high |
| Big Bass Splash | Pragmatic Play | High |
| Sweet Bonanza 2500 | Pragmatic Play | High |
| Sugar Rush 1000 | Pragmatic Play | High |
| Le Zeus | Hacksaw Gaming | High |
| Mental 2 | Nolimit City | Very high |
Labels are a rough guide only; the paytable inside each game is the authority.
Jackpots and Hold & Win
Hold & Win games such as 3 Pyramids of Gold Hold & Win, Coin Blitz 2 and 4 Clover Pots trigger a respin round where coin symbols lock in place and each new coin resets the counter. Fill the grid or land special symbols and you can unlock fixed jackpot tiers. These are fun, but the bonus round is where most of the value sits, so expect quieter base play.
UK slot rules
What changes for GB players
- Stake cap: £5 per spin, or £2 per spin if you are aged 18–24.
- No autoplay or turbo: every spin is manual and takes at least 2.5 seconds.
- No bonus buys: bonus buys are banned for GB players, so you trigger features through normal play.
- Verification first: age and identity checks happen before any play, including demos.
These rules are set by the UK Gambling Commission and apply at every licensed site. If verification is holding you up, our KYC & withdrawals guide lists the documents to have ready.
