Hub88 Review 2026: Games, API and Integration

By Soft of Games editorial team · Updated 2026-10-07 · Methodology

Hub88 is a game aggregator that grew out of Yolo Group's own crypto casinos and now serves outside operators, including Stake.com since 2024. It lists 26,000+ games on its site in October 2026 and offers a well-documented seamless wallet API with RSA signatures, a Freebets API and supplier promotions that operators join with one click. Pricing is opaque, the provider count is not published and onboarding still runs through sales.

Key facts

Hub88 has an unusual origin for a B2B supplier. It was built inside Yolo Group (formerly Coingaming) to serve the group’s own crypto brands, Bitcasino.io and Sportsbet.io, before it was opened to outside operators. That history explains a lot about the product: it is opinionated about wallets, comfortable with crypto and less obsessed with having the biggest number on the homepage.

A deliberately mid-sized catalogue

Hub88 lists 26,000+ games on its homepage in October 2026. That is smaller than the 40,000-plus figures quoted by several rivals, and Hub88 does not publish a provider count on its site at all. Third-party reviews and the company’s own job listings give different numbers, which suggests they are counted in different ways.

Content keeps arriving. In March 2026, Tequity added its 17 Originals titles and a range of Crypto Trading games to the hub. That fits the pattern: Hub88 leans toward content that works for crypto audiences and streamer-style play.

The practical advice is simple. Ask for the live studio list, then check it against the ten studios that drive most of your revenue. A smaller hub with every game you need beats a larger one with gaps.

The API is the strong point

Hub88 publishes its developer documentation openly, and it is good. The Wallet API is a seamless design: you expose endpoints, Hub88 calls them to read the balance and post bets and wins. A TransferWallet option exists for operators who prefer that model.

Security is handled properly. Requests are signed with RSA-SHA256 using 2048-bit keys, and the Base64 signature travels in the X-Hub88-Signature header. Every wallet transaction carries a transaction_uuid, and a repeated request must return the same response without being processed twice. The docs even warn developers to verify the raw body before parsing it, a detail that saves real debugging time.

Compared with an HMAC-based callback setup, such as the one SoftAggregator uses, RSA signing takes a little more setup work with key pairs. It is not a reason to choose one hub over the other, but your developers should know which they are building.

Free bets and supplier promotions

Two features stand out for marketing teams.

The Freebets API grants free spins, free bets or prizes to one or more players. Most suppliers on the hub support it, mainly for first-time player offers. Some games need the player to open them before the reward lands, which should be explained in your bonus terms.

The second is supplier promotions. Studios create campaigns in Hub88, and operators opt in with one click. For a small CRM team, that is free activity on the lobby without negotiating each campaign separately.

Hub88 does not advertise its own tournament or jackpot engine, so leaderboards still need a separate tool.

Onboarding and the back office

There is no self-service sign-up. You contact sales, agree terms and then receive credentials and a technical contact. Integration time is not published. The homepage uses the phrase “Minutes, Not Months”, which is a slogan rather than a measured timeline.

Once live, the back office has become richer. It includes Player Analytics, a HubWallet settlement feature and an AI assistant called Hub AI that answers product questions from inside the dashboard.

Markets and clients

Hub88 is headquartered in Tallinn, Estonia. Its best-known client is Stake.com, which signed an aggregation partnership in May 2024 that later grew to include live dealer content and crypto-related services. The rest of its client base leans toward crypto-friendly brands that operate internationally.

The currency list is not published. Crypto support is part of the company’s DNA, but confirm specific fiat currencies if you serve markets in Africa or South Asia.

Support

Support runs through your technical contact, the public knowledge base and Hub AI. Documentation quality reduces the number of tickets you will need to open, which is the best kind of support. For incident handling, ask for response time commitments before signing.

What the Stake relationship means for other clients

Hub88’s biggest showcase is also a fair question for any smaller operator. When one of the largest crypto casinos in the world runs its game catalogue through your aggregator, its needs naturally shape the roadmap.

That works in your favour in several ways. The infrastructure is tested at very high volume. New studios are motivated to integrate quickly, because the reach is attractive. Features built for a big crypto operator, such as wallet settlement or fast crypto-friendly content, become available to everyone else.

It can also work against you. If a studio offers an exclusive or early release, a large partner may get it first. Support teams may prioritise the accounts that generate the most turnover. None of this is unusual, but it is worth raising directly.

Useful questions for the sales call:

• Which games or studios on Hub88 are not available to all clients?
• How many operators share my support queue, and what is the response time for a broken game?
• Is the Freebets API supported by every studio I plan to feature in my welcome offer?
• Which supplier promotions ran last quarter, and what share of operators joined them?

The answers will show whether Hub88 treats mid-sized operators as partners or as a long tail.

Who should look at Hub88

Hub88 suits crypto-first operators with in-house developers who appreciate a clean, well-documented API, and marketing teams that want free bets and supplier promos without extra tooling.

It is less suited to operators who measure aggregators by raw catalogue size, or to buyers who need published pricing. Founders who want to be live within days with instant API keys will find SoftAggregator quicker to start. ST8 and Slotegrator are the other names to compare.
