Novomatic's Greentube Summer 2026 Slots: Flaming Devil, Golden Sizzling Hot and the Piggy Prizes Push

Greentube is Novomatic’s digital gaming and entertainment division, and its summer 2026 output shows a studio working almost entirely in franchises: extend Cash Connection, extend Piggy Prizes, and drop one standalone title with a collect mechanic. The company previewed its pipeline at iGB L!VE in London on 1-2 July 2026 (European Gaming coverage, 22 June 2026) and then shipped through July and August. Here is what actually arrived, with the numbers we could verify — and honest gaps where we couldn’t.

Flaming Devil — the August headliner

Released on 18 August 2026 (European Gaming, 18 August 2026), Flaming Devil is the one genuinely new face in the batch: a fire-and-brimstone fruit-adjacent theme with a grinning devil as collector-in-chief.

Layout: 5 reels, 243 ways to win — no fixed paylines.
Devil Collect Feature: active on every spin, not gated behind a bonus round. The devil gathers symbol values continuously through the base game.
Free Games Wheel: the free-spins round runs through a wheel that can stack extra spins and multipliers on top of the trigger award.
RTP: 95.00%, volatility rated 3 of 5 (medium) per iGB’s game listing. Max win is not published.

“The Devil Collect feature is active on every spin, not just during the bonus round, so there’s always something to keep attention fixed,” — Richard Ganster, Director of Games Strategy at Greentube (G3 Newswire).

For UK players the 95% base RTP is worth pausing on: it sits roughly 1.5 percentage points below the 96.5% default that Pragmatic Play and most Tier-1 competitors ship. Over a long session that difference is real money. The trade is a collect mechanic that fires constantly, which makes the game feel busier than its maths. Always check the in-game info panel — UK operators must display the active RTP under UKGC LCCP rules.

Cash Connection – Golden Sizzling Hot

Greentube’s release announcement went out on 14 July 2026 (G3 Newswire), folding the classic Novomatic Sizzling Hot fruit machine into the Cash Connection jackpot family. Note that SlotCatalog’s listing records an earlier market debut, so treat July 2026 as the wide-rollout announcement rather than a world premiere.

Layout: 5×3, 5 win lines — deliberately old-school.
Lock & Spin: the Cash Connection hold-and-respin engine. Landing disc symbols locks them in place for respins; each new disc resets the counter.
Four jackpot tiers: Mini, Minor, Major and Grand. Landing 15 discs fills the grid and awards the Grand Jackpot; the Mini or Minor tiers additionally open a Winning Spins feature in which every spin pays.
RTP: listed at 95% on SlotCatalog. Volatility and max win are not published by the provider.

This is retro-market product engineering: Sizzling Hot has been running in Novomatic land-based cabinets and online lobbies for two decades, and the Cash Connection wrapper is how Greentube keeps that audience on modern jackpot mechanics. If you grew up on five-line fruit slots, this is aimed squarely at you; if you want ways-wins and tumbles, it isn’t.

Piggy Prizes Wish of Riches 2

Announced on 23 June 2026 and front and centre on Greentube’s iGB L!VE stand in July, Piggy Prizes Wish of Riches 2 extends what Greentube calls one of its strongest game families (G3 Newswire). The company says the title was developed primarily by its UK studio — relevant, because the feature set reads like it was tuned for UK lobby tastes.

Layout: 5×3.
Genie economy: locked coin and jackpot symbols act as wilds; a Super Genie adds and boosts coin values; piggy pots grow as the Genie feeds them and burst to award six Free Games. Filling a pot to capacity via the Super Genie triggers Super Free Games.
Magic Spin / Magic Rewind: pre-spin modifiers that can plant a Genie on the centre reel or replay chances at valuable symbols.
Xtreme Bet: an optional high-volatility mode at 5× the standard stake that strips the reels to premium symbols only.
RTP: 95.06%, volatility low-medium per SlotCatalog; max win not published.

One UK-specific caution: Xtreme Bet multiplies your effective stake fivefold, and the UKGC online slot stake caps of £5 per spin (25+) and £2 (18-24), in force since 2025, apply to the total staked per spin. On a capped account the mode simply compresses your base stake range rather than unlocking bigger spins.

Announced, not yet live: Highway to Bell Stack & Collect

Greentube used iGB L!VE to give Highway to Bell Stack & Collect — a rock-and-roll themed stack-and-collect title — its first public showing, with launch slated for later in 2026 (AGB, 23 June 2026). No RTP, layout or date has been published, so we list it as announced only.

What the batch says about Novomatic’s direction

Three signals stand out. First, franchise depth over novelty: of the summer titles, only Flaming Devil is not a line extension, and even it is built on a familiar collect chassis. Greentube’s stated strategy pairs game families — Cash Connection, Piggy Prizes, Diamond Link, Starlight Jackpots — with its regulated-market rollout. Second, conservative maths: both published RTPs in this batch sit at 95.0-95.1%, below the competitive default, with volatility pitched low-to-medium. Greentube is building session-length games for regulated markets, not max-win screenshots for streamers. Third, distribution keeps widening: the company took its slot catalogue live in Ontario through a bet365 integration this summer (Gambling Insider), consistent with a regulated-first posture that fits UKGC-licensed lobbies well.

For UK players the practical takeaway: Greentube titles are widely distributed on UKGC-licensed sites, the maths is gentler but slower, and the jackpot families are fixed-tier rather than must-drop — read the paytable, not the marketing.
