The CasinoGo sister sites in a nutshell
CasinoGo is the casino-only newcomer from Annexio (Jersey) Limited, the company that has been taking bets on lottery draws through LottoGo for years. That makes LottoGo its one and only sister site, so I’ve added four UK-licensed casinos worth a look alongside it.

I’ve profiled CasinoGo’s one sister site below, followed by four CasinoGo sister site alternatives from other UK-licensed operators, each picked because it does something fans of CasinoGo might like.
LottoGo
- The original: LottoGo lets you bet on the outcome of big lottery draws without buying a ticket, and it runs Lottery, Syndicates and Scratchcards options that CasinoGo doesn’t have.
- Same site, purple shade: Its Most Popular row contains the same slots as CasinoGo’s, from Big Bass Splash to Book of Dead, just reshuffled, under a purple header where CasinoGo’s is blue.
- A slightly smaller bonus: The welcome offer works the same way but tops out at £200 and 100 free spins, against CasinoGo’s £250 and 150.
- Its own fishing trip: LottoGo has an exclusive Big Bass LottoGo Vegas slot, which is the one game I’d single out as a reason to pick it over its sister site.
- A long track record: More than 21,000 Trustpilot reviews averaging 4.2, on a profile it’s held since 2015, where CasinoGo has a handful.
- Best for: Players who fancy a flutter on EuroMillions or the US jackpots as well as a spin, and want both under one login.
Tombola Arcade
- Relationship: Not a sister site. Tombola Arcade is run by Tombola (International) Plc on its own Gambling Commission licence, 38613.
- Another spin-off: Like CasinoGo it grew out of a different game, bingo in Tombola’s case, and every slot on it is made in-house.
- Your money first: It matches your first deposit up to £50 and uses your own cash before the bonus, much like CasinoGo, but also gives you a free play for every £1 deposited.
- No wagering fuss: The homepage promises that anything you win is yours to keep, which is friendlier than CasinoGo’s 10x wagering requirement and cap.
- A daily league: The Prize League runs a daily leaderboard on selected slots at any stake.
- Best for: Casual players who like low stakes, a bit of friendly competition and games they won’t find anywhere else.
Fun Casino
- Relationship: Not a sister site. Fun Casino belongs to L & L Europe Limited of Malta, on UKGC licence 38758, with no regulatory actions against it.
- Cash, not bonus: Deposit and wager £10 and you get 100 cash spins on Big Bass Splash at 10p each, with winnings paid as cash and no cap on what you can withdraw.
- The same fish: It’s the same slot CasinoGo gives its welcome spins on, only without the 10x wagering and £37.50 ceiling per batch.
- Extra categories: Slingo, video poker and a sportsbook are available alongside the slots and live casino.
- One catch: Skrill deposits don’t count for the offer, and the spins expire 48 hours after they land.
- Best for: Slots players who’d rather keep what they win from the start than work through a bonus.
Casushi
- Relationship: Not a sister site. Casushi is run by Solaya Group Limited of Gibraltar on UKGC licence 100050.
- Small but sweet: A £10 deposit and £10 on slots earns 40 free spins on Big Bass Splash, with no wagering and cash winnings.
- Fewer spins, fewer strings: That’s under a third of CasinoGo’s 150 spins, but none of them come with a wagering requirement.
- The sushi one: The name is a casino-and-sushi pun, and its Popular Games row opens with Buffalo Blitz III, Big Bass Vegas 1000 and The Jokeress 10000.
- A lower entry point: The qualifying deposit is £10, half of CasinoGo’s £20 minimum for its welcome offer.
- Best for: Players testing a new casino with a small deposit who want a sign-up deal that’s easy to understand.
Rainbow Riches Casino
- Relationship: Not a sister site. Rainbow Riches Casino runs on Gamesys Operations Limited’s UKGC licence, 38905.
- The famous leprechaun: It’s home to the full Rainbow Riches slot series, from Pick N Mix to Megaways.
- A simple welcome offer: Play £10 and get 30 free spins on Rainbow Riches Pick N Mix, and with no wagering requirements, anything you win is yours to keep.
- More to explore: Slingo, a Sports tab and a weekly rewards wheel for invited members sit alongside the slots, where CasinoGo sticks to casino and live games.
- Plenty of time: Spins expire 30 days after your deposit, far more time than CasinoGo’s seven days.
- Best for: Fans of classic British pub-style slots who want a big, well-known name as the focus point.

A blue casino with Big Bass on repeat
CasinoGo keeps things simple. It opens with a bold blue banner and a casino chip for the O in its logo, with just two tabs (Casino and Live Games), and a homepage that goes straight from the welcome banner to the Most Popular slots. That row is Big Bass Splash, Fluffy Favourites, Fishin’ Frenzy Lure ‘Em In, Golden Winner Grand Chance, Rich Wilde and the Book of Dead and Triple Train Express, with King Kong Splash Power Play, Big Bass Vegas Double Down Deluxe and Eye of Horus close behind. If you like fishing slots, you’ll feel right at home, with a full Big Bass Jackpots section and one shared prize pot running across more than a dozen games.
The lobby itself goes much deeper than the homepage lets on. Scroll through the full list and you’ll pass well over 2,000 games from more than 30 studios, led by Games Global, Pragmatic Play, Yggdrasil, Octoplay, Booming Games, Spinberry and Play’n GO, with Hacksaw, Nolimit City, ELK, Push Gaming, Relax, Red Tiger and NetEnt among the rest. Evolution is among the studios responsible for the live casino line-up. I’ll give CasinoGo credit for that range, as it’s far more than a brand-new site usually launches with. The only thing I’d change straight away is the About Us page, which still boasts of “over 1,000 games” and then ties to sell you lottery betting that CasinoGo doesn’t offer, but more on that below.
A casino still using LottoGo’s paperwork
You’d be forgiven for thinking CasinoGo is a lottery site that’s lost its lottery. Its About Us page opens by inviting you to “bet on the outcome of lotteries including the legendary US Mega Millions and Powerball”, and goes on to explain how lottery betting works, none of which you can do on casinogo.com. The Player Terms and Conditions, dated 17 September 2026, mention draws 56 times, syndicates 22 times and lotteries 43 times, and CasinoGo by name just once. The Promotion Terms even list jackpot caps for EuroMillions, Powerball, and Mega Millions bets, and the footer on every page still says Annexio “does not operate a lottery”. It’s all LottoGo’s terms, copied and pasted across with the name changed, but the attention to detail lacking.
To be fair, the shared paperwork has one upside. The terms say Annexio treats its brands as one for safer gambling, so if you self-exclude at CasinoGo, the exclusion covers LottoGo too, and any limits you set may follow you across. That’s exactly how it should work for a two-brand family.
Ownership and licensing
UKGC Licensed, Annexio (Jersey) Limited (51692), click to verify
CasinoGo’s footer names its operator directly: Annexio (Jersey) Limited, Jersey company 125819, of De Carteret House on Castle Street in St Helier. It holds Gambling Commission account 51692 for Britain and a Jersey Gambling Commission licence, RGO-011-23, at home. On the Commission’s register, its remote casino and real-event betting activities date from 31 July 2018 and bingo from 20 March 2020. It lists just two domains, casinogo.com and lottogo.com, and three trading names, those two plus Affiliate Empire, which is the group’s affiliate programme rather than a third casino. There are no regulatory actions on record. The About Us page describes Annexio as a provider of secondary lottery and lottery betting services, with offices in London, Jersey and Australia and its headquarters on the Isle of Man.
Bonuses: a second chance, not a guarantee
The promotional banner on the CasinoGo homepage promises “Deposit & get up to £250 & 150 free spins”, and I’ll be honest, I read it as a standard matched deposit at first. It isn’t. Deposit anything from £20 to £250, and bonus cash appears in your balance straight away, but it stays switched off until you’ve lost your deposit and anything you won while playing it. Only then does the bonus come to life, with 10x wagering to complete within seven days, a £5 maximum bet and a cap of five times the bonus on what you can turn into cash. Table and live games count 10% towards the wagering, and some slots are excluded. If your first deposit goes well, you keep your winnings and the bonus never kicks in. So it’s really a safety net for a bad session, which is no bad thing, but the banner could be a lot more direct about this.
The 150 free spins are worth 10p each and arrive in two batches: 75 straight away and 75 a day later, once you’ve wagered your deposit once. Winnings from the spins count as bonus money, carry the same 10x wagering requirement, and are capped at £37.50 per batch. Oddly, the terms tell you to claim the offer from “the Promotions area”, but there isn’t one attached to any of the side menus, and the only other promotions the terms describe are LottoGo-style lottery subscription deals. The general promotion terms also limit each bonus to one per household, IP address or phone number.
Payments: next-day withdrawals and a 90p fee
You can deposit with Visa or Mastercard debit cards, PayPal, Apple Pay, or Google Pay, and the terms set the minimum deposit at £5, although the welcome offer requires £20. Withdrawals go back to the method you used to deposit. The Help Centre says most are processed automatically and reach your bank the next day, though some banks take up to five working days, and a withdrawal showing as pending can take three to five business days to clear. There’s no minimum withdrawal, but anything under £10 costs a 90p bank charge, and once you’ve requested a withdrawal it’s locked in and can’t be reversed.
Two details are worth knowing before you deposit. The Help Centre says deposits can’t be withdrawn, only winnings, but the terms say you can ask for unplayed deposits back for a £2 administration fee, so if you change your mind, it’s the terms you’ll want to quote. And every account starts with a monthly deposit limit of £100,000 plus a net deposit limit on losses, which you can lower at any time. Customer money is held in a separate trust account at the Commission’s “Medium” level of protection. An account left untouched for 12 months can be closed with an administration fee, and although the terms say the balance then belongs to Annexio, they also let you ask for it back later.
Support and complaints: chat, email and IBAS
The Contact link opens a live chat window, and the Help Centre lists help@casinogo.com for everything else, including complaints, which it asks you to label “complaint” in the subject line. There’s no customer support phone number, even though the terms say you can complain by email, phone or post. They acknowledge complaints within two business days. The aim is to resolve them within five working days; you can ask for a manager’s review, and you’ll get a formal written response within eight weeks. Still unhappy after that? You can take the dispute to IBAS, the free adjudication service, by calling 020 7347 5883 or emailing adjudication@ibas-uk.co.uk. The terms are governed by English law with disputes heard in Jersey’s courts. One small bit of housekeeping: the welcome banner and footer still send you to GambleAware, even though that charity stopped work in March 2026, so the GAMSTOP and GamCare links beside it are the ones to use if you need to.
What I like, and what I don’t
What I like
- A massive lobby of well over 2,000 slots on a clean, simple site.
- PayPal, Apple Pay and Google Pay, with withdrawals usually landing the next day.
- Customer funds at the Medium protection level and IBAS named for disputes.
- Self-exclusion that covers both brands in the family.
What I don’t
- A welcome bonus that only becomes valid after you’ve lost your deposit, which the homepage doesn’t mention.
- About Us and terms pages written for LottoGo, not CasinoGo.
- No phone line, despite the terms offering phone-based complaints handling.
- Mixed messages on getting a deposit back, and a 90p charge on small withdrawals.
My CasinoGo sister sites verdict: fine, but not finished
I’ve got to say, CasinoGo has more going for it than most brand-new casinos. It’s backed by a company with years of UK licensing behind it, the games are plentiful, and the cashier and complaints route are the sort you’d hope for. What it hasn’t done yet is become its own site. It’s LottoGo with the lottery taken out, and it shows in the paperwork, in the missing Promotions area and in a welcome offer you’ll only ever be able to use if things go badly.
If you want lottery bets and slots in one place, LottoGo is the more complete version of the same product and has the track record to back it up. If you’re here purely for slots, I’d look at Fun Casino or Casushi first, where the spins pay cash with no wagering, or Tombola Arcade and Rainbow Riches Casino for a more generous welcome promotion and a bigger name. CasinoGo might be worth a look further down the line once it’s grown into its clothes.
CasinoGo sister sites FAQ: your questions answered
What are CasinoGo’s sister sites?
Just one: LottoGo. Both sites run on Annexio (Jersey) Limited’s Gambling Commission licence, 51692, which lists no other domains. I’ve also suggested four UK-licensed alternatives: Tombola Arcade, Fun Casino, Casushi and Rainbow Riches Casino.
Who owns CasinoGo?
Annexio (Jersey) Limited, a Jersey company based in St Helier, which also runs LottoGo. It’s licensed in Britain under account 51692 and in Jersey, and it has no regulatory actions on its record.
How does the CasinoGo welcome bonus work?
Deposit between £20 and £250 and a bonus of up to £250 appears, but it only switches on after you’ve lost that deposit. It then needs 10x wagering within seven days, with a £5 maximum bet and winnings capped at five times the bonus. You also get 150 free spins at 10p.
Is CasinoGo safe?
In licensing terms, yes. It holds a Gambling Commission licence with a clean record, keeps customer funds at the Medium protection level, names IBAS for disputes and applies self-exclusion across both of Annexio’s brands. Just read the welcome terms before you deposit.
How fast are CasinoGo withdrawals?
Usually by the next day, as most requests are handled automatically, but allow up to five working days depending on your bank. Small withdrawals under £10 cost 90p.
