Second instalments and new series versions in the Dukat.bet lobby

When we treat a game as the next part of a series

“Series” here does not mean a hit game, only that a studio has released at least two parts under one brand – the original and a later game that follows on from it in name and mechanics. We have no play statistics.

A game gets into the snapshot only if it came out in 2025 or 2026 and was listed in the Dukat.bet lobby on the snapshot date. A seasonal release also counts as a “new version” if the studio presented it as a standalone game with its own page.

The key is the date the studio released the sequel. It is not the day the game arrived in the lobby – the lobby API does not give that, just as it gives no RTP or release date. If dates matched, the alphabet would decide.

The original’s year is there for orientation only.

Ten sequels from Chicken Rush 2 to Gold Party 2

For BGaming games the studio also states the cap in euros (for example €250,000 for Aviamasters 2); that is the limit at the highest stake, not another multiple. Where the RTP says “up to” or carries a note on versions, only the paytable of the running game shows which configuration Dukat.bet uses.

What the studios reworked in the new instalments

1 · Chicken Rush 2 – the biggest change in the ten. The original Chicken Rush of 15 May 2024 was a 243-line slot; according to BGaming the sequel is a casual road-crossing game with Easy, Medium, Hard and Hardcore levels. A golden egg sharply raises the multiplier and an auto mode was added – so the genre changed entirely.

2 · The Big Dog House – Pragmatic Play turns wilds into 1×1, 1×3 or 3×3 blocks with a ×2 or ×3 multiplier. In the free spins (9 to 27) they are sticky, but “ghosts” can remove them; Biggie and Ghost Out modifiers are new. Reviewers call the 15,000× cap a record for the series.

3 · Sweet Bonanza 2500 – the principle stayed; the studio raised free-spin bomb multipliers to 2,500× and the win ceiling to 25,000×.

4 · Fishing Club 2 – three locations (dawn, dusk, twilight), five risk levels and two bonus buys: Fishing Net at 60× and TNT at 100× the stake. Volatility rose from medium-low to medium.

5 · Aviamasters 2 – four boosters (Magnet, Laser Gun, Nitro, Life Buoy) and a Safe Landing option that, for 50× the stake, guarantees the plane lands. The cap moved from 250× to 1,000×, volatility from low to medium.

6 · Aviamasters X-mas – a Christmas version of the original, not a full second part. Santa’s sleigh replaces the plane, ice obstacles halve the balance, and Big, Mega and Super Mega notices pop up at x20, x40 and x80. The cap stayed at 250×.

7 · Coin Win 2: Hold The Spin – Gamzix’s second game in the series. We found no studio list of changes, so we do not invent any; independent sources give medium volatility, 5,000× and RTP versions from 92 to 96%. The original (11 August 2023) sits in the operator’s “Recommended” tab.

8 · Plinko 2 Halloween – a Halloween reskin of Plinko 2 with unchanged mechanics: risk levels, up to 100 balls, a ×2/×4 Multiplier Ball and Respin Chance. Yet the studio lists very high volatility for it, versus low for Plinko 2.

9 · Gonzo's Quest II (Return to El Dorado) – fourteen years after the first game (a 5-reel, 20-line slot), NetEnt built the sequel on a grid that grows during a round from 6×4 to 6×8 – taking the ways to win from 4,096 up to 262,144. Volatility is high.

10 · Gold Party 2 – After Hours – ×2/×3/×5 wilds multiply each other, and Money Respin runs on four 3×5 grids. The super pot goes up to 200×, the multiplier symbol up to 25× and four bonus prizes up to 10,000×. The original’s year is disputed: most sources say January 2022, some reviewers 2020; we use 2022.

Why the sequel order will not stand forever

A release date never changes, but the surroundings do. One more instalment or seasonal version in the lobby is enough, and Gold Party 2 drops out first.

A game can also leave the lobby, or the operator can switch to another RTP configuration. If a studio later publishes its own figures, they take precedence over reviewers. A new check would come out with a new date; this state is not quietly rewritten.

The youngest slots regardless of series are tracked in the list of newest slots by date.

Candidates that did not fit into the ten

Four games stayed in reserve:

• Chicken Road Race (InOut, 18 November 2025) – a “speed-run” version of Chicken Road (4 April 2024) where every step raises the multiplier; RTP 95.5%. By date it would rank eighth, but InOut gives no figure for its top payout, which would leave the row incomplete.
• The Dog House – Royal Hunt (Pragmatic Play, 31 March 2025) – 96.50%, 8,000×. It is older than Gold Party 2.
• Winter Fishing Club (BGaming, 28 January 2025) – a winter reskin of Fishing Club with no mechanical changes, 97.16% and 3,000×; again the date decides.
• Fire Express 2: Hold & Win (ENJOY Gaming) – released on 24 April 2026 only as a single-operator exclusive; the general release date is unknown and the 94.01% RTP has one source.

How we set the date for exclusives and early access is described on the release dates page.

Why are Big Bass Halloween 2, Wolf Gold Ultimate and The Dog House – Muttley Crew missing? All three are in the lobby, but came out in 2024: Big Bass Halloween 2 on 21 October 2024 (96.71%, 5,000×), Wolf Gold Ultimate on 7 November 2024 (96.50%, 5,000×) and Muttley Crew in October 2024. The same goes for Dog or Alive of 28 March 2024. They are series, but outside the 2025–2026 window. We did not count the branded remake Penalty Duel with Julio Cesar (BGaming, 8 June 2026) as a series instalment.

A new instalment need not have better maths than the original

The date only tells you which part is younger, not whether it returns more – Plinko 2 Halloween got a different volatility under the same rules, and Chicken Rush 2 is a completely different game from the first one.

Sample calculation with fictitious numbers – not Dukat.bet data: the original runs in a 96% version, the sequel in a 94% version. Over 500 rounds at 0.40 EUR, 200 EUR staked, the theoretical loss is 8 EUR in the first case and 12 EUR in the second. High volatility pushes a short session even further from the average.

RTP is a long-run average – a higher number does not mean you will win. Why one game has several configurations is covered in the article on RTP versions.

Slots Bonus for slots and instant sequels

The offer tied to this snapshot: Slots Bonus – 500% up to 3,000 EUR + 15% Cashback. The cashback has no visible terms of its own on the bonus page, so we do not go into it.

Five games in the ten are slots, and under point 2.14 of the general rules (checked on 11 October 2026) they count 100%. Chicken Rush 2, Fishing Club 2, both Aviamasters and Plinko 2 Halloween, however, are instant titles (more fresh ones in the list of new instant games). Point 2.14 says nothing about them and point 2.15 excludes several instant games, Plinko among them – so check in the offer terms and the excluded-games list whether a given sequel counts towards a slot bonus.

Under point 2.7 the default max bet while wagering is 5 EUR, including a bonus buy (such as TNT in Fishing Club 2) or the Safe Landing option. Point 2.9 sets the standard lifetime of a bonus at 14 days.

For players over 18 only.
