The Westio Sportsbook
Many casino-first operators bolt a sportsbook on as an afterthought. This one is a genuine part of the product: more than 40 sports, a live in-play section, a bet builder, cash out and a dedicated esports area, all running on the same account and wallet as the casino. You log in once, deposit once, and move between the slot floor and a Premier League match without transferring funds.
The layout is clean. The left rail lists sports in order of popularity for UK players, the centre shows today's events and the bet slip sits on the right (or slides up from the bottom on mobile). Odds can be displayed in fractional or decimal format, and the slip handles singles, doubles, trebles, accumulators and system bets such as Yankees and Lucky 15s. For a 2026 launch, the depth of markets on the main football leagues is better than we expected.
Sports Covered
Here are the eight sports that matter most to UK bettors and how each is covered.
Football
The centre of the book. Every Premier League, EFL and Scottish Premiership fixture is priced, alongside the major European leagues, the Champions League and international tournaments. Big matches carry well over a hundred markets, including player props, cards, corners and the bet builder.
Horse Racing
Daily cards from UK and Irish courses, with win and each-way betting, forecasts and tricasts. Festival meetings such as Cheltenham, Aintree and Royal Ascot get expanded ante-post markets.
Tennis
ATP, WTA and Challenger events, with match, set and game betting. Tennis is one of the busiest in-play sports on the site, as prices move point by point.
Cricket
Test, one-day and T20 cricket, including the County Championship and the major franchise leagues. Markets cover match result, top batter, top bowler and session runs.
Basketball
The NBA leads, followed by the EuroLeague and major domestic leagues. Point spreads, totals and player points are all available pre-match and live.
Golf
Outright winner, each-way, top-10 finishes and head-to-head matchups on the PGA and DP World tours, with expanded markets for the four majors and the Ryder Cup.
Darts
The PDC calendar is well covered, from the Premier League of Darts to the World Championship at Alexandra Palace. Markets include match winner, correct score in sets and most 180s.
Esports
A dedicated section for Counter-Strike 2, Dota 2, League of Legends and Valorant, with map winners, totals and live markets on the main tournaments.
Beyond these eight you will find rugby union and league, boxing, MMA, snooker, American football, ice hockey, cycling, motor sport and more — over 40 sports in total.
Live In-Play Betting
The in-play section lists every event currently running, grouped by sport, with a count of live markets on each. Prices update in real time and the slip confirms any odds change before you place the bet, so you are never accepted at a price you did not see.
Most live football matches show an animated match tracker with possession, shots and dangerous attacks; tennis shows a point-by-point scoreboard. Cash out is offered on most singles and many accumulators, both in full and, on selected bets, as a partial cash out. Bet acceptance was quick in our testing, with only a short delay on goal-sensitive markets — normal across the industry and designed to prevent bets being placed after the event has happened.
The in-play view also works well for multi-event viewing. You can pin several matches to a watchlist and follow their prices side by side, which is handy on a busy Saturday afternoon when several Premier League and EFL fixtures kick off at 3pm. Live markets on football include next goal, total corners, cards and the remaining-time result; tennis adds next game and set winner; cricket offers runs in the next over. Bet acceptance is confirmed on screen and appears in your open bets straight away, with settlement normally within minutes of the market closing.
Welcome Sports Bonus
New UK customers who choose the sports offer get a straightforward deal: bet £10, get a £10 free bet. Place a qualifying £10 bet on any sport once your first deposit has cleared, and the free bet is credited after the qualifying bet settles.
- The free bet stake is not returned with any winnings — only the profit is paid.
- Minimum odds and the expiry date for the free bet are listed in the offer terms.
- Payments by debit card, Apple Pay, PayPal, Skrill, Neteller, Paysafecard, Revolut, Open Banking or bank transfer all qualify.
The sports offer is separate from the casino welcome package of 150% up to £500 + 200 Free Spins, so check which one you are opting into at sign-up. The full rules for both sit on the bonuses page, and the payments guide explains deposit and withdrawal times.
Mobile Sportsbook
There is no app-store app, but the sportsbook runs as a progressive web app from Safari or Chrome and can be added to your home screen in a couple of taps. On a phone, the bet slip slides up from the bottom of the screen, the in-play list loads quickly over 4G, and the bet builder works with simple tap-to-add selections.
Notifications for settled bets and cash-out offers can be switched on in the browser. Because the casino and the sportsbook share one wallet, you can check a live score between hands at the live tables without logging in twice. Our mobile experience score for the whole site was 9.0.
The PWA is light on storage and updates itself automatically, so there is nothing to download when new features arrive. Deposit limits, bet history and self-exclusion tools are all available in the mobile account menu, not hidden behind the desktop version.
Responsible Sports Betting
Sports betting can feel like a skill game, and that makes it easy to chase losses or bet more often than planned, especially with in-play markets open around the clock. The site provides the standard UK toolkit:
- Deposit limits by day, week or month, which also cover casino play.
- Reality checks, time-outs and self-exclusion, with GAMSTOP support.
- A full bet history so you can see what you have actually staked and won.
Bet with money you can afford to lose and treat any free bet as a bonus rather than a reason to stake more. Free, confidential help is available from BeGambleAware.org, GAMSTOP and GamCare. You must be 18 or over, and identity and age checks are completed before you can bet.
What's Next
The Westio sportsbook is a genuinely useful second half of the site rather than a token add-on: deep football and racing coverage, a solid in-play section with cash out, a bet builder and a proper esports area, all in one wallet with the casino. The UK welcome offer is simple to understand, with its terms set out in plain English.
If you want the casino side as well, browse the slots and the live casino, or compare offers on the bonuses page. Ready to place a bet? Open the sportsbook and claim your £10 free bet. 18+ only. BeGambleAware.org.
