Best Blueprint Gaming Slots & Casinos: Top 10 Ranked

About Blueprint Gaming

Blueprint Gaming was founded in 2001 in Newcastle, UK, with a deliberate focus on adapting physical pub fruit machines into online slots. The studio’s early titles — King Kong Cash, Slots O’ Gold, Genie Jackpots — were almost all direct ports of pub-machine hits, giving Blueprint immediate brand recognition with UK players who’d grown up on the physical originals. This UK pub-machine DNA remains the studio’s distinctive identity nearly 25 years later.

The Gauselmann acquisition

Blueprint was acquired by Gauselmann Group in 2008 — the German gaming conglomerate that also owns Merkur Gaming, Edict, and several other slot brands. The acquisition gave Blueprint scale and platform access while letting the Newcastle team retain creative independence. Most of Blueprint’s signature hits (Fishin’ Frenzy 2014, Genie Jackpots Megaways 2019, Buffalo Rising Megaways 2020) were developed post-acquisition.

The Fishin’ Frenzy explosion

If one slot defines Blueprint, it’s Fishin’ Frenzy (2014). The original was a steady performer for years; the franchise then exploded into a series of variants — Fishin’ Frenzy Megaways, Fishin’ Frenzy Even Bigger Catch, Fishin’ Frenzy The Big Catch, Fishin’ Frenzy Bigger Catch — each riding the original’s success. Fishin’ Frenzy is now the most-played fishing-theme slot in UK online gambling, paralleled only by Pragmatic Play’s Big Bass Bonanza series.

Megaways licensing era

Blueprint licensed the Megaways engine from Big Time Gaming in 2018 and used it to re-launch existing Blueprint IPs as Megaways adaptations. Fishin’ Frenzy Megaways (2019), Genie Jackpots Megaways (2019), Eye of Horus Megaways (2020), Buffalo Rising Megaways (2020) and Diamond Mine Megaways (2018) all leverage the franchise recognition with the higher-grid mechanic. The Megaways line now sits at the top of Blueprint’s commercial catalogue.

The Jackpot King network

Blueprint’s proprietary progressive jackpot network — a multi-tier shared pool that layers onto Blueprint base slots. Available at Sky Vegas, Coral, William Hill and other Blueprint-friendly UK operators. The network is covered in detail in a later section on this page.

The 10 best Blueprint Gaming slots in 2026

Ranked by RTP, max-win potential, series strength and UK player popularity. Blueprint’s catalogue spans extremely-popular UK-specific titles, Megaways adaptations, and Jackpot King network slots.

1. Fishin’ Frenzy Megaways

The highest max win in mainstream Megaways at 50,000x — only beaten in the wider slot world by select Nolimit City titles. The Fisherman bonus where fish symbols carry collectible cash values gives Fishin’ Frenzy Megaways a distinctive bonus structure that other Megaways slots can’t replicate. Universally available at UKGC casinos.

2. Primal Megaways

The highest-RTP Megaways slot in Blueprint’s catalogue at 96.71%. Prehistoric theme paired with the standard Megaways engine and an unlimited multiplier in free spins. Underrated compared to the Fishin’ Frenzy franchise but mechanically and mathematically stronger.

3. Fishin’ Frenzy (original)

The slot that built Blueprint’s modern catalogue. Medium volatility, modest max win (1,000x), but the Fisherman bonus in free spins is one of the most-loved slot mechanics in UK online gambling. The 25-payline grid feels small after experiencing Fishin’ Frenzy Megaways but the original still holds up as a relaxed-session pick.

4. Genie Jackpots Megaways

Blueprint’s Megaways update of the classic Genie Jackpots series. The Wishing Bonus mechanic lets the player choose between Wild Reels, Mystery Symbols or Lamp Cleaning Bonus for their free-spins round — an unusual amount of player agency for the Megaways format. 96.50% RTP is well above the Megaways average.

5. Eye of Horus Megaways

Blueprint’s Megaways take on the Egyptian-theme classic Eye of Horus. Combines the Book of Dead-style expanding-symbol mechanic with the Megaways engine — a hybrid you don’t see often. RTP and max win sit at the higher end of Blueprint’s range.

6. Buffalo Rising Megaways

American-prairie theme on the standard Megaways engine. Solid 96.52% RTP and 10,000x max win. The Buffalo Power Spins bonus is a respectable take on the free-spins format with Mystery Symbol mechanics that link to other Blueprint titles in the catalogue.

7. Diamond Mine Megaways

One of Blueprint’s earliest Megaways adaptations, with a UK-pub-machine-style mining theme. The Extra Gold variant of Diamond Mine Megaways pushes max win up to 50,000x — matching Fishin’ Frenzy Megaways for catalogue ceiling. The TNT-symbol bonus is genuinely fun.

8. Eye of Horus (classic)

The non-Megaways Eye of Horus. Cheaper-stake play than the Megaways adaptation and a more traditional 10-payline grid. Higher RTP than Fishin’ Frenzy (96.31% vs 96.10%) and a slightly higher max win. The cleanest entry point into Blueprint’s Egyptian-theme catalogue.

9. Slots O’ Gold Megaways

Megaways update of one of Blueprint’s earliest UK-pub-machine adaptations. Irish-luck theme, Pot of Gold respin mechanic, 96.50% RTP. Familiar to anyone who’s played the pub-machine original; the Megaways grid brings it up to modern visual standards.

10. Genie Jackpots (Jackpot King)

The original Genie Jackpots tied to the Jackpot King progressive jackpot network. Lower base RTP than non-jackpot Blueprint titles (95.05%) — the trade-off for network jackpot eligibility. Available at Sky Vegas, Coral, William Hill and other Jackpot King-equipped casinos.

Highest-RTP Blueprint Gaming slots

Blueprint’s catalogue clusters tightly around the 96.10–96.71% RTP range — less variance than competitors like BTG or Pragmatic Play. The studio doesn’t have any elite 98%+ RTP outliers, but its 96.50%+ slots are reliably available at the top RTP version across UK casinos. Ranked by published RTP:

For pure expected-value play, Primal Megaways at 96.71% leads the catalogue. The 96.50% group (Buffalo Rising, Genie, Eye of Horus, Diamond Mine, Slots O’ Gold Megaways) all sit close behind — if you’ve a preference for theme, you can pick almost any without sacrificing much RTP. The Jackpot King-network slots run lower base RTPs (typically 94–95%) due to the network jackpot funding. See our high RTP slots guide for the broader cross-provider context.

The Jackpot King network — Blueprint’s flagship

Jackpot King is Blueprint Gaming’s proprietary progressive jackpot network, deployed across many of the studio’s slots. Unlike network jackpots from other providers (Microgaming’s Mega Moolah, Playtech’s Age of the Gods), Jackpot King is operator-specific rather than fully cross-casino — the jackpot pools are scoped to individual operator groups rather than the whole UK market.

How Jackpot King works

Jackpot King layers a progressive jackpot bonus on top of Blueprint’s base slots. When the jackpot bonus triggers, players enter a special spinning-reel game where they collect coins to climb tier ladders. The standard tier structure is:

• Regal Jackpot — the top tier, typically seeded above £50,000
• Royal Jackpot — second tier, typically £5,000–£20,000
• Side Pots — smaller mystery-jackpot wins typically £25–£500 paid randomly during base play

Jackpot King-eligible slots

Many Blueprint slots have Jackpot King variants. The headline titles:

• Genie Jackpots (Jackpot King)
• Eye of Horus Jackpot King
• Slots O’ Gold Jackpot King
• Diamond Jackpots Jackpot King
• The Goonies Jackpot King
• King Kong Cash Jackpot King
• Chicago Gold Jackpot King

Each takes an existing Blueprint slot and overlays the jackpot bonus. Base RTPs run typically 94–95% (lower than non-jackpot versions to fund the prize pool).

Where to play Jackpot King

Jackpot King is operator-licensed rather than open across the UK market. The strongest casinos for Jackpot King access:

• Sky Vegas — broadest Jackpot King catalogue alongside its proprietary Sky Vegas Jackpot promotions
• Coral Casino — deep Jackpot King library via Coral’s Playtech / Blueprint platform integration
• William Hill Casino — comprehensive Jackpot King selection
• Ladbrokes Casino — sister site to Coral with the same Jackpot King access

Jackpot King vs other UK network jackpots

Jackpot King sits between Yggdrasil’s Empire Fortune and Microgaming’s Mega Moolah in scale. The top tier (Regal) typically peaks lower than Mega Moolah’s Mega tier but hits more frequently — weeks rather than months between top-tier wins. For UK players who want jackpot eligibility on familiar Blueprint titles, Jackpot King is the right network. See our jackpot slots guide for the broader category context.

Blueprint Gaming’s signature mechanics and licensed IPs

Beyond Jackpot King, Blueprint has built a distinctive identity around four recurring elements:

The Fishin’ Frenzy formula

The most replicated mechanic in Blueprint’s catalogue. Fishin’ Frenzy’s Free Spins round features a fisherman wild who collects fish symbols (each carrying a cash value) when he appears. The mechanic appears in every entry of the Fishin’ Frenzy series — original, Megaways, Even Bigger Catch, The Big Catch, Bigger Catch, Reel ’em In, Prize Lines, Jackpot King. Pragmatic Play later borrowed the formula for Big Bass Bonanza, but Blueprint did it first and the franchise remains the most-played fishing-theme slot family in UK online gambling.

Mystery Symbol mechanic

A recurring Blueprint feature where a Mystery Symbol lands during play and transforms into a single random symbol type, often producing chained wins. Used across Buffalo Rising Megaways, Buffalo Rising, multiple Blueprint Megaways titles, and several jackpot variants. Adds variance to base-game play without altering RTP.

Megaways adaptations (BTG licence)

Blueprint licensed the Megaways engine from Big Time Gaming in 2018 and used it primarily to upgrade existing Blueprint IPs. Fishin’ Frenzy Megaways (2019), Genie Jackpots Megaways (2019), Eye of Horus Megaways (2020), Buffalo Rising Megaways (2020), Diamond Mine Megaways (2018), Slots O’ Gold Megaways (2020), Primal Megaways (2019). The Megaways line now sits at the top of Blueprint’s commercial catalogue.

Branded slots and TV/film licences

Blueprint has historically held several branded-slot licences, with mixed durations. Notable entries:

• The Goonies — one of Blueprint’s longest-running licensed IPs, with multiple variants including Jackpot King
• Ted — based on the 2012 film, ran for years
• Ace Ventura — one of the more entertaining branded entries
• Inspector Gadget — cartoon-IP branded slot
• Top Cat — classic cartoon-IP entry

Like Playtech, Blueprint has lost some branded licences over time as IP-holders consolidate or change licensing strategies. Some titles remain available; others have been withdrawn.

UK pub-machine heritage

Blueprint’s earliest catalogue (King Kong Cash, Slots O’ Gold, Genie Jackpots, Eye of Horus, Robin Hood) was almost entirely composed of online adaptations of physical pub fruit machines. This gives Blueprint a recognisability with UK players that competitors lack — UK casual gamblers often recognise Blueprint slots from physical pub experiences before seeing them online.

Where to play Blueprint Gaming slots in the UK

Blueprint slots are universally available at UKGC-licensed casinos. The differentiator is whether the casino carries the Jackpot King network (operator-licensed, not cross-market) and which Blueprint titles are prioritised in their lobby. A few sites stand out:

• Sky Vegas — the strongest Jackpot King access in the UK. Sky Vegas runs Jackpot King alongside its proprietary Sky Vegas Jackpot promotion, layering two jackpot networks at the same casino. Strong Fishin’ Frenzy and Eye of Horus depth.
• Coral Casino — comprehensive Jackpot King catalogue and the full Megaways lineup. The Playtech-IMS platform that powers Coral also lets the casino run multi-provider promotions across Blueprint and Playtech titles.
• William Hill Casino — long-running Blueprint partner with deep Jackpot King access. Particularly strong for the Genie Jackpots and Eye of Horus franchises.
• Ladbrokes Casino — sister site to Coral with the same Jackpot King access and Playtech platform integration.
• Mr Vegas — not Jackpot King-equipped but carries the full non-jackpot Blueprint catalogue across its 5,500+ slot library. Particularly good for Fishin’ Frenzy Megaways and Primal Megaways.
• bet365 Casino — comprehensive Blueprint selection with industry-leading PayPal withdrawal speeds.

Welcome bonus eligibility for Blueprint slots

Most UK casinos accept Blueprint slots for welcome-bonus play. The exception: Jackpot King-network slots are sometimes excluded from bonus wagering due to their lower base RTP, particularly at Coral, William Hill and Ladbrokes. Always check the bonus T&Cs before depositing if you intend to play Jackpot King titles with bonus money.

Mobile and UK availability

Every Blueprint slot is HTML5-native and runs smoothly on iOS and Android browsers. Modern releases (the Megaways line, Primal Megaways, the post-2020 Fishin’ Frenzy entries) are portrait-orientation-native; older titles have been retrofitted to mobile. The UK pub-machine-DNA classics (King Kong Cash, Slots O’ Gold) have been remastered for mobile and run cleanly.

Responsible gambling

Blueprint’s catalogue includes slots designed for casual UK-pub-style sessions (Fishin’ Frenzy, King Cash) alongside higher-volatility Megaways adaptations and lower-RTP Jackpot King variants. The casino always wins on average; the difference is how slowly. Set a budget before you start, never chase losses, and only gamble with money you can afford to lose.

All UK-licensed casinos are required by the UK Gambling Commission to offer a range of tools to help you stay in control:

Deposit limits: set a daily, weekly or monthly cap so you can’t deposit more than you’ve decided to spend.

Loss limits and session limits: automatically log out or stop play after a set time or loss amount.

Reality checks: on-screen reminders showing how long you’ve been playing and how much you’ve spent or won.

Time-out and self-exclusion: short cooling-off periods, or — through GamStop — full self-exclusion from every UKGC-licensed casino in the UK simultaneously.

If your gambling stops being fun, free, confidential help is available 24/7 from BeGambleAware or the National Gambling Helpline on 0808 8020 133.

You must be 18 or over to gamble. Always check the full terms of any bonus before opting in.
