Cazino Cosmos: Pros and Cons

Reviewed by Brian Taylor
Published: October 2018
Updated: July 2026

Pros

• The wild-line chase that made Cazino Zeppelin famous. Land Stella on every reel during free spins and the wilds stick for the rest of the round, paying a five-of-a-kind wild line on every remaining spin, the exact moment streamers go quiet, because a full wild line is where the 11,821x stake ceiling actually lives.
• Five distinct Collection Free Spins modes add real decisions. Rather than one bonus, you can unlock reel-by-reel collectible modifiers that change how wilds, extra spins and transforming symbols behave, it gives the sequel depth the original never had.
• An 11,821x ceiling that Yggdrasil’s own testing confirmed. The studio’s billion-spin certification recorded a top win of exactly 11,821x stake, the highest of any Yggdrasil slot at launch, so the headline number is documented rather than theoretical.
• A genuinely beautiful brass-and-nebula presentation. The reels sit inside a drifting space-station casino framed in oxidised copper and neon, with a moody score, it keeps the warm bronze palette of Cazino Zeppelin while moving the setting to deep space.

Cons

• Brutal high variance with a hit rate near 27%. Around three in four spins return nothing, so without a strong sticky-wild bonus your balance drains fast, several players describe long, profitless sessions.
• The collection bonuses can underwhelm. A recurring complaint is triggering the enhanced Collection modes and still cashing out modest amounts, the features add variety but do not guarantee the wins their build-up promises.
• Scatters can vanish on the drop. Players report scatters appearing then disappearing before the free spins trigger, which on a slot this dependent on the bonus feels especially deflating.
• It is structurally a re-skin. The core sticky-wild mechanic is lifted wholesale from Cazino Zeppelin and NetEnt’s Dead or Alive, so anyone who has played those will find little genuinely new beyond the collection layer.

How Cazino Cosmos Works

Cazino Cosmos keeps things deliberately traditional under the steampunk styling: five reels, three rows and 20 fixed paylines, paying left to right only, with no Megaways or cascades. That simplicity is the point, the whole game is engineered to funnel you towards the free spins, where the sticky wilds do the heavy lifting. In the base game you are really just fishing for three scatters while collecting the occasional Stella wild.

It runs on Yggdrasil’s iSENSE 2.0+ engine across desktop and mobile, with autoplay up to 1,000 spins. Because almost all the win potential is locked behind the bonus, patience is not a style choice here, it is a requirement of the maths.

One label worth flagging: Yggdrasil’s own game page bands Cazino Cosmos as “High” volatility, while we rate it Very High on our internal scale. Both are defensible, the roughly 27% hit frequency concentrates so much of that 96.0% return into the free spins that it plays noticeably swingier than most games sitting in the developer’s own “High” tier.

Symbols and Paytable

There are four low-value symbols and four premium space-explorer characters, topped by Stella the matriarch, who doubles as the wild. The game logo is the scatter that opens the free spins. A single wild line of five Stellas is the big-money combination, which is why stacking and sticking wilds during the bonus matters far more than anything that happens in the base game.

Sticky Wilds and the Free Spins Feature

Three, four or five scatters award 10, 15 or 20 free spins. Any Stella wilds on the triggering spin carry into the round and become sticky, as does every wild that lands during the feature, and landing one wild on each of the five reels awards five extra spins. The aim is to lock wilds into a full line so that, for the rest of the bonus, every spin pays a five-of-a-kind wild win. It is a slow build that turns into an avalanche the moment the line completes, and that tipping point is the single clearest signal a huge result is coming.

The Five Collection Free Spins Modes

What separates Cazino Cosmos from its predecessor is the Collection layer. Across the five reels you can unlock five different collectible features that bolt extra behaviour onto the sticky-wild round, additional wilds, extra free spins and transforming symbols among them. Each mode reshapes how a bonus plays out, so two free-spins rounds rarely feel identical, and choosing which collection to chase introduces a genuine strategic edge that the original Zeppelin formula lacked.

Cazino Cosmos Player Reviews

Games like Cazino Cosmos

Slots like Cazino Cosmos divide along two lines: the Yggdrasil family feel and the sticky-wild free-spins mechanic. Our index groups it with Booster, Chibeasties 2, Campers Cash and Adventure Palace, though the closest spiritual matches are Cazino Zeppelin and Dead or Alive.

Booster is a slot built by Isoftbet. The reels form a 5 reel, 3 row layout offering 25 paylines. On return it edges out Cazino Cosmos, which runs 96.0%. It returns 97.40%, which is high for the market. Treat it as a guide to long-run payback rather than a promise for any one session. On the bonus side you get free spins and increasing multipliers. You can bet from 0.25 to 50 per spin, leaving room for cautious and bigger play alike. Expect medium-low volatility here, so wins land fairly regularly and tend to be modest, which keeps sessions steady. Players who like it tend to try Candy Dreams as well. It sits close to Cazino Cosmos in feel, making it a natural follow-on.

Chibeasties 2 is a Funfair slot from Yggdrasil Gaming. It is played across a 5-reel, 3-row grid with 20 paylines. Bets start at 0.2 and reach 100 a spin, covering most bankrolls. On return it edges out Cazino Cosmos, which runs 96.0%. Return to player sits at 96.20% and counts as medium-high overall. In practice that means the game pays back around that share of stakes over a long run of spins, not in any single session. It plays at medium volatility, which means you get a balanced pace, with wins that are neither tiny nor rare. Headline features include free spins, expanding wilds, pick a prize bonus and shifting wilds. Specific touches include select a realm of mirroring wild, spreading wild, teleporting wild and expanding wild and free spin mode. It is frequently grouped with Celebrity in the Jungle. If you liked Cazino Cosmos, Chibeasties 2 is an easy one to try next.

Developed by Nuworks Gaming, Campers Cash carries a Jackpot theme. It is played across a 5-reel, 3-row grid with 9 paylines. On return it gives back slightly less than Cazino Cosmos, which runs 96.0%. It returns 95.66% and counts as medium overall. That figure is a long-term average rather than something to expect back each session. Stakes run from 0.01 up to 50 a spin, so it suits both small and larger budgets. It plays at medium volatility, which means it strikes a middle ground, mixing a fair hit rate with the odd larger payout. The feature set covers free spins and progressive jackpot. Specific touches include free spin feature, scatter symbol and wild symbol. Players who like it tend to try Candy Cash and Aldos Journey as well. If you liked Cazino Cosmos, Campers Cash is an easy one to try next.

Developed by Microgaming, Adventure Palace carries a Cats theme. You spin a 5 reel, 3 row grid with 9 paylines in play, a tighter setup that keeps things simple. Bets start at 0.01 and reach 45 a spin, covering most bankrolls. Volatility is medium-low, so wins land fairly regularly and tend to be modest, which keeps sessions steady. Headline features include free spins, increasing multipliers and improving symbols. In play that shows up as wild elephant, palace scatter, substitution of wining symbols and free spins multiplier. The RTP is 96.10%, which is medium-high for the market. In practice that means the game pays back around that share of stakes over a long run of spins, not in any single session. On return it edges out Cazino Cosmos, which runs 96.0%. It also draws comparisons with Candyland. Fans of Cazino Cosmos should find plenty to like here.

Booster
Booster is a 2017 iSoftBet game with 25 paylines and a high 97.40% RTP at medium-low volatility. It is a far gentler ride than Cazino Cosmos, so it suits players who want the space flavour without the punishing variance.

Chibeasties 2
Chibeasties 2 is a 2017 Yggdrasil stablemate with 20 paylines and a 96.20% RTP at medium volatility. If you like Cazino Cosmos for the studio’s polish rather than the sticky wilds, this is the natural next click.

Campers Cash
Campers Cash is a 9-line Nucleus Gaming title with a 95.66% RTP and medium volatility, a lighter, lower-stakes free-spins game that shares little of Cazino Cosmos’s ambition but offers an easy palate cleanser.

Adventure Palace
Adventure Palace is a 2004 Microgaming classic, a 9-line 5×3 slot with a 96.10% RTP and medium-low volatility. It is here for its free-spins simplicity rather than any real resemblance to Cazino Cosmos’s sticky-wild engine.

Editor’s note: for a wider view beyond our own testing, here is a snapshot of how other independent outlets summed up Cazino Cosmos. Our own verdict, reached after playing the game ourselves, follows later in this review.

Cazino Cosmos slot critic’s reviews

VegasSlotsOnline.com: Our reviewers of the Cazino Cosmos slot liked the steampunk theme as well as spinning the reels on this Yggdrasil creation. The win potential is massive, while the extra collectible features add even more opportunities to hit those much-wanted wild lines in the free spins.

Online-Slot.co.uk: Cazino Cosmos is quite simple once you get spinning those reels, basically, there’s a standard Free Spins feature where wilds become sticky and you can win extra free spins.

TheSlotBuzz.com: Cazino Cosmos is an excellent follow-on from Zeppelin. It re-produces the gameplay of the first slot entirely with the sticky wild-free spins combo before adding more than a dash of enhanced gameplay with extra wilds, free spins and transforming symbols to create a whole new level of excitement in the Collection Free Spins round.

BigwinBoard.com: Keeping the core mechanics while adding a whole new set of features was a brilliant move, making Cazino Cosmos a worthy follow-up that will appeal to both conservative and progressive players.

AskGamblers.com: Cazino Cosmos is a superbly designed slot with steampunk vibe that we personally liked playing. It is packed with features and ridiculously high winning potential that can go as high as x11821.

Slots that feel like Cazino Cosmos

Cazino Cosmos is not a nature-and-mountains adventure slot, it is a steampunk space opera. The reels sit aboard a drifting space-station casino, the cast are futuristic explorers, and the whole thing carries the warm bronze, brass-and-neon look that Yggdrasil established in Cazino Zeppelin.

If you enjoy slots like Cazino Cosmos for that retro-futurist atmosphere, the theme matters as much as the maths, the look and the moody soundtrack are a big part of why the game built a following.

Other atmospheric, feature-led slots players cross-shop with Cazino Cosmos include Gonzo’s Quest, Treasure Skyland, Hidden Valley and Mighty Arthur, though for the true sticky-wild experience Cazino Zeppelin and Dead or Alive are the direct relatives.

In short, Cazino Cosmos is a steampunk sci-fi slot set in a casino among the stars, the space-casino angle is the theme, not a generic adventure quest.

Cazino Cosmos was created by Yggdrasil

Yggdrasil Gaming was founded in 2013 and made its name with a string of design-led, high-volatility slots. It holds a UK Gambling Commission licence and its iSENSE engine powers crisp, mobile-first releases like Cazino Cosmos.

The studio’s breakthrough was Cazino Zeppelin in 2015, widely seen as the first credible alternative to NetEnt’s Dead or Alive, thanks to its sticky-wild free spins. Cazino Cosmos is the direct sequel to that game.

Cazino Cosmos shows the studio’s approach well: keep the beloved sticky-wild core, then add genuine novelty on top, here, the five Collection Free Spins modes that the original lacked.

Other well-known Yggdrasil titles include Vikings Go To Hell, Valley of the Gods, Jungle Books and Rainbow Ryan. The catalogue has kept growing since, with releases like Dwarf Mine and Brazil Bomba carrying the same design-led, high-volatility DNA that runs through Cazino Cosmos.

More Yggdrasil games from the same studio worth a look are Gem Rocks, All Star Knockout Ultra Bonus, Arthurs Fortune and Liliths Inferno.

Cazino Cosmos FAQs

What is the max win on Cazino Cosmos?

The top win is 11,821x your stake, a figure Yggdrasil’s own billion-spin testing recorded exactly. It was the highest ceiling of any Yggdrasil slot at launch, and it comes almost entirely from completing a sticky wild line in free spins.

What is the RTP of Cazino Cosmos?

Cazino Cosmos has a flat 96% RTP, a single config that is the same at every casino. It is reasonable for a high-volatility slot, but check the figure at your operator before you play in case of variant setups.

How do the sticky wilds work in Cazino Cosmos?

Any Stella wild that lands during free spins sticks to its position for the rest of the round. Land a wild on all five reels and you get five extra spins, and lining wilds up on a payline pays a five-of-a-kind wild win on every remaining spin.

How do you trigger free spins in Cazino Cosmos?

Land three, four or five scatters in one spin for 10, 15 or 20 free spins respectively. Any wilds on the triggering spin are carried in as sticky wilds.

What are the Collection Free Spins in Cazino Cosmos?

Cazino Cosmos adds five separate collectible free-spins modes across the reels, each layering extra behaviour, more wilds, extra spins or transforming symbols, onto the sticky-wild round. They are the main thing the sequel adds over Cazino Zeppelin.

Is Cazino Cosmos like Dead or Alive?

Yes. Both share the sticky-wild free spins where a full wild line drives the biggest payouts. Cazino Cosmos descends from Cazino Zeppelin, which was Yggdrasil’s answer to NetEnt’s Dead or Alive, so the bonus feels very familiar.

Is Cazino Cosmos high volatility?

Very. The hit rate is around 27%, so most spins return nothing and the value is concentrated in the free-spins bonus. It is a slot that demands a healthy balance and patience.

What slots are like Cazino Cosmos?

The closest slots like Cazino Cosmos are its predecessor Cazino Zeppelin and NetEnt’s Dead or Alive, all built on sticky-wild free spins. You can browse the full similar-slots list on our index.

Who makes Cazino Cosmos?

Yggdrasil Gaming, founded in 2013 and the studio behind Cazino Zeppelin. Yggdrasil holds a UK Gambling Commission licence.

Our Verdict on Cazino Cosmos

Cazino Cosmos is one of the best sticky-wild slots ever made, and that is both its strength and its limit. If you live for the wild-line chase that made Cazino Zeppelin and Dead or Alive streaming legends, this is the most refined version of that idea, with five Collection modes adding decisions the originals never offered and a documented 11,821x ceiling. But it is unforgiving, a 27% hit rate and bonuses that sometimes fizzle mean it is for patient bonus-chasers, not players who want steady action. If you enjoy slots like Cazino Cosmos, start with Cazino Zeppelin for the purest version and Dead or Alive for the slot that started the whole lineage.
