InstaSpin lists 3,793 games across slots, jackpots, table games and a live casino, supplied by eight named studios: Hacksaw Gaming, Spribe, Play’n GO, Wazdan, Novomatic, InOut, Swintt and Relax Gaming. The library runs on the operator’s own platform under a licence from the Union of the Comoros, and the site is in English. A page about the brand at biggsopticians.co.uk covers the same ground if you want a second summary of what is on offer.

Slots make up the bulk of that figure, with jackpot titles and live dealer tables filling out the rest. The welcome package is built around one slot in particular: Big Bass Bonanza, which comes with 10 free spins a day for 10 days on a first deposit. The brand also runs a sportsbook alongside the casino, so the games sit in one half of a larger site.

Eight studios and a 3,793-game library

The provider list is short and deliberate. Hacksaw Gaming is known for high-volatility slots, Spribe for quick crash-style games, Play’n GO and Relax Gaming for a broad spread of themes, Wazdan for adjustable volatility settings, Novomatic for classic fruit machines, and InOut and Swintt for a mix of modern and traditional titles. Between them they cover the four game types the brand advertises.

What stands out is the balance between quantity and recognisable names. A library of 3,793 games is large, and it is built from studios that players in the United Kingdom will meet at many operators, which makes the catalogue easy to navigate if you already know what you like. The live casino sits in its own lobby, and jackpots are grouped separately from standard slots.

Our preference here is for the slots section, for a factual reason: the welcome package and the recurring free spins promotion both point at slot play, so most of the value on the games side sits there rather than in the live dealer lobby. If table games are your main interest, the catalogue has them, but the promotions do not lean that way.

One gap to know about: biggsopticians.co.uk has no dedicated app. The website is optimised for mobile devices, so the games run in a browser on a phone, but there is nothing to download from an app store.

How to find a game and check its RTP

RTP stands for return to player, the share of stakes a game pays back over a very long run. It is set per game, not per casino, and the figure is published inside the game itself.

1. Log in and open the games lobby from the main menu.
2. Filter by game type (slots, jackpots, table games, live casino) or search by title.
3. Narrow the list by provider if you want to see one studio’s output, for example Hacksaw Gaming or Play’n GO.
4. Open a game and look for the information or “i” button, usually in a corner of the screen.
5. Read the RTP figure in the paytable or help screen before you spin. The same game can run at different settings, so check each title you plan to play.
6. If the figure is missing from the help screen, ask customer support for the RTP of that specific game before you deposit.

The RTP check takes under a minute per game and tells you more about a title than any promotional description will.

Strengths and weaknesses of the games line-up

The catalogue has real depth, and the provider roster is the reason.

• Eight named studios, including Hacksaw Gaming, Play’n GO, Relax Gaming and Novomatic.
• 3,793 games across slots, jackpots, table games and live casino.
• Mobile-optimised website, so the full lobby works on a phone browser.
• Casino and sportsbook on one account.

On the other side, the drawbacks that touch this topic are worth stating plainly.

• No dedicated app: mobile play happens in the browser only.
• Only English is offered as a site language.
• No information about the operator appears on the official site.

The missing operator details matter for games because they are the people you would contact about a disputed spin or a stuck round. The English-only site is a smaller point for readers in the United Kingdom, though it does mean no translated help pages. Weighing the two lists, the games catalogue is the stronger half of the offer, and the app gap is the one you will notice day to day.

What to check in the T&Cs before you deposit

Game rules and bonus rules are separate documents, and the second one decides how your deposit behaves.

• The wagering requirement: the welcome package carries 40x. The bonus terms state whether that applies to the bonus alone or to deposit plus bonus.
• Which games count towards wagering, and at what percentage. Slots usually count in full, table games often less.
• The role of Big Bass Bonanza in the free spins offer: 10 spins a day for 10 days, and what happens to unplayed spins.
• The maximum bet allowed while a bonus is active.
• Whether a pending withdrawal can be turned into bonus money, and what that means for your balance.
• The expiry date on bonus funds and free spins.

As a hypothetical example, a $100 deposit taken with a 100% bonus gives $200 of bonus-inclusive balance, and at 40x on the bonus alone that is $4,000 of wagering before withdrawal. Check the terms for the exact base.

Questions players ask about the InstaSpin games lobby

Are the slots from big-name studios?

Yes. The roster names Hacksaw Gaming, Spribe, Play’n GO, Wazdan, Novomatic, InOut, Swintt and Relax Gaming. Each studio’s titles appear in the lobby, and you can filter by provider to see one at a time.

Can I play on my phone without downloading anything?

The website is optimised for mobile devices, so games load in the browser. There is no dedicated app, and nothing in the brand’s information describes one.

How do I know a game’s RTP before I play?

Open the game’s help or information screen and read the published figure. If it is not shown there, ask customer support for the RTP of that title. The brand’s own materials do not list RTP figures for individual games.

Our verdict on the games, and your next step

For a player who wants a large slots library from studios they already recognise, InstaSpin makes a solid case: 3,793 games, eight providers and a mobile site that loads the full lobby in a browser. The sportsbook on the same account adds a second reason to look. The licence comes from the Union of the Comoros, and the operator is not identified on the official site, which is the detail we would want resolved before depositing. English is the only site language.

Your next step is to open the lobby, filter to the provider you trust most, and read the RTP on two or three titles before you put money in. Then read the bonus terms for the 40x requirement and the game-weighting rules.

Gambling is for adults only (18+). If gambling is causing you problems, free and confidential support services are available in the United Kingdom. Play only with money you can afford to lose, and treat a bonus as no reason to deposit more than you planned.
