Captain Bones Big Bounty takes you on a maritime treasure hunt where everything revolves around gold chests, chains of Cash symbols, and the pursuit of four fixed jackpot levels. The slot is developed by Alchemy Gaming (Games-Global-Affiliate) and is the third entry in the Big Bounty series, following Big Bounty Gold and Bronco Big Bounty. Content-wise, it directly continues the same concept: the Big Bounty mechanic remains central, where a predefined bounty value during free spins determines the progression of the bonus round.
The game is played on a 6-reel grid with 4 rows each. Instead of traditional paylines, it uses 4,096 ways to win, allowing combinations whenever at least 3 matching symbols land on adjacent reels from left to right. This multiway setup creates a large, interconnected grid where combinations constantly overlap and interact.
The theme places you in a pirate universe: a pirate crew featuring a pirate woman, a pirate man, a ship, and a skull island forms the top symbols. These are supported by standard card symbols from 9 to A. The two captain characters are the highest-paying regular symbols.
The setting reinforces the atmosphere: an open sea with white waves and light and dark clouds in the background. On the left side of the semi-transparent reels sits a treasure chest filled with gold coins, along with the jackpot display, including a 5,000x mega prize. This value refers to the stake multiplier (for example about 5,000 CHF on a 1.00 CHF bet).
Technically, Captain Bones Big Bounty features a maximum win of 5,481x the stake. The four jackpots – Mini (15x), Minor (50x), Major (250x), and Mega (5,000x) – are integrated as fixed multipliers throughout the feature set. Additional features include Wild symbols, Cash Collect, free spins with Big Bounty Win, Wheel Bonus Game, Plunder Party, Upsizer feature, and a Feature Buy option.
The Big Bounty system works as follows: in the base game, the value starts at 10x. When you land 5 Scatter symbols (the letters of the word BOUNTY), this value increases by +2.5x up to a maximum of 50x. This value determines when the free spins round ends, which only stops once a single win meets or exceeds the threshold.
Overall, Captain Bones Big Bounty is a slot that clearly focuses on a combination of multiway gameplay, fixed jackpots, and a structured free spins system, without unnecessary complexity but with tightly interconnected features.
At first glance, Captain Bones Big Bounty stands out for its calm maritime setting. The sea in the background is rendered in shades of blue, with soft breaking waves while light and dark clouds move across the horizon. The reels themselves are semi-transparent, so the ocean scene always remains visible instead of being boxed in.
On the left side of the grid sits a treasure chest filled with gold coins, with coins seemingly spilling over the edge. Above it is a jackpot display highlighting the four jackpot tiers—Mini, Minor, Major, and Mega—with the 5,000x Mega prize prominently displayed at the top. This immediately makes it clear that the jackpot structure is central to the gameplay.
The visual direction is classic pirate-themed, featuring slightly cartoonish but detailed characters. The two pirates—a female and a male character—are strongly defined and stand out clearly from the background. The pirate ship and skull island integrate smoothly into the overall scene without overwhelming it. Overall, the design feels modern but not exaggerated, more like a polished adventure game that tells its story through symbols and scenery.
Animations are clearly structured: during the Plunder Party feature, a dedicated animation plays before cash symbols land on the reels. The Wheel Bonus Game, with its jackpot wheel spin, also uses a visually emphasized presentation. Win sequences and feature triggers are therefore easy to follow and well structured.
Interestingly, the game does not use continuous background music. Instead, you constantly hear ambient ocean sounds. This choice enhances the adventure feel without overloading the slot with a constant soundtrack. Additional audio layers—such as reel spins, wins, or feature triggers—sit on top and provide clear feedback whenever something happens on the grid.
The symbol set in Captain Bones Big Bounty is clearly structured, with many motifs directly tied to gameplay features. The regular and special symbols can be summarized as follows:
Instead of a continuous music loop, Captain Bones Big Bounty relies mainly on ocean ambience. The sound of waves and sea breeze creates an acoustic foundation that fits the calm yet structured gameplay.
During spins and feature triggers, additional effects are layered in: reel spin sounds, short win jingles, and emphasized audio cues when the Plunder Party starts or the Wheel Bonus Game appears. The overall soundscape stays focused and supports clear readability of what is happening on the reels.
Captain Bones Big Bounty combines its strengths in a tightly packed feature set. Cash Collect, Big Bounty Free Spins, Plunder Party, Wheel Bonus Game, Upsizer and Feature Buy mesh like gears and revolve around the same core elements: Cash symbols, Jackpot symbols and the Big Bounty value. The following table gives you a structured overview before we dive into the details.
| Feature | Trigger | Core message / Effect |
|---|---|---|
| Wild symbol | Appears on reels 2–6 | Replaces all regular symbols, but not scatter, coins, keys, cash or jackpot symbols. |
| Cash Collect | Chain of cash symbols from left to right | Collecting cash values (0.2x–10x) and, in the base game, jackpot symbols on reel 6 or in free spins also on unlocked reels 3–6. |
| Free Spins with Big Bounty Win | 6 scatters in the base game | Unlimited free spins that only end when a single reel win reaches or exceeds the Big Bounty value (10x–50x); includes bonus guarantee. |
| Big Bounty increase | 5 scatters in the base game | Increases the Big Bounty value by +2.5x, up to a maximum of 50x, before free spins start. |
| Wheel Bonus Game | Coin symbol on reel 6 randomly triggers the wheel | Jackpot wheel with Mini (15x), Minor (50x), Major (250x), Mega (5,000x); guarantees one of the four prizes. |
| Plunder Party | Random trigger in any game round | Guarantees at least 6 cash symbols on the grid after the spin ends. |
| Upsizer Feature | Before free spins start | Optional increase of the Big Bounty value up to a maximum of 50x for an additional cost, if available. |
| Feature Buy (Bonus Buy) | Manual activation via buy button (regional availability) | Instant access to free spins for 120x the bet with a bonus guarantee of 60x. |
The Wild symbol is a W and appears on reels 2 to 6. It replaces all regular symbols, helping to complete or extend paylines. Its limited role is important: Scatter, coin, key, cash, and jackpot symbols are never replaced by Wilds. This fits well with the slot's structure, as these special symbols carry their own mechanics and should not be diluted.
The Cash Collect mechanic is a core part of Captain Bones Big Bounty. Cash symbols can land on all reels and carry values from 0.2x to 10x the bet. There are two categories:
For these values to become relevant, cash symbols must form a connected chain from the first reel to the right. As soon as such a chain is formed, all multipliers contained within it are summed up and added to the total.
In the base game, reel 6 plays a special role: if a cash chain lands from reels 1 to 5 and one or more jackpot symbols appear on reel 6, these jackpots are triggered as well. This allows the Mini, Minor, Major, or Mega prizes to be activated directly via the regular reel grid.
In free spins, this mechanism is expanded, as jackpot symbols can land on reels 3–6 and can be integrated into the game even better via key symbols.
The free spin feature of Captain Bones Big Bounty has a clear special feature: there is no fixed number of spins. Instead, you indirectly define a win threshold, the Big Bounty value, and the free spins run until a hit reaches or exceeds this threshold.
How it starts:
As soon as the free spins run, the following applies: The free spins only end when a single reel win reaches or exceeds the current Big Bounty value. All wins between 10x and 50x are classified as a Big Bounty Win. Additionally, a bonus guarantee works in the background, ensuring a minimum total value within the free spin round.
During free spins, key symbols appear and land on cash symbols. Each key:
Once these reels are unlocked, a chain of cash symbols from left to right can not only collect their own values but also activate jackpot symbols on reels 3–6 for you.
Important: Free spins cannot be retriggered. After the round ends, the Big Bounty value in the base game is reset to 10x. This creates a clearly structured sequence: build up bounty in the base game, trigger free spins, reach the Big Bounty threshold, then start over.
The Wheel Bonus Game is the second major way to reach the jackpots. It is triggered randomly when a coin symbol lands on reel 6. When the bonus game is activated, a wheel with four segment types appears, each corresponding to a jackpot:
Every spin of the wheel guarantees one of the four prizes. For a bet of 1.00 CHF, the Mega Prize would correspond to an amount of around 5,000 CHF, for example. The wheel mechanic creates a clearly focused moment: a short spin decides which of the four levels becomes active.
The Plunder Party is a random event that can occur during any spin in the base game or in free spins. When triggered, its own animation starts, and at the end of the spin, at least 6 cash symbols land somewhere on the reels.
Especially in combination with the Cash Collect mechanic, this function can lead to several values adding up to a considerable sum or – if a chain is formed – even jackpots being collected. The Plunder Party is thus a kind of cash booster that can occur independently of scatter or coin hits.
Before starting the free spins, Captain Bones Big Bounty offers the Upsizer Feature. Here you can optionally increase the Big Bounty value beyond the current level, up to the maximum value of 50x.
This adjustment is made for an additional cost, which is displayed before confirmation. You can confirm or cancel the purchase. In some cases, the feature may be restricted, such as if the set bet exceeds a certain threshold or if the function is not available in certain regions.
As a further option, a Feature Buy is available in designated environments. Via a Buy button, you can purchase direct entry into the free spins. The price is 120x the bet.
The free spins triggered via the Feature Buy include a bonus guarantee of 60x the bet. This guarantee indicates the minimum value aimed for within the bonus round. The concrete access to the free spin structure remains identical: here, too, the round runs until the Big Bounty value is reached or exceeded by a single reel win.
Captain Bones Big Bounty positions itself as a slot that plays out its pirate theme not through gags or overloaded effects, but through a clear mechanical structure. The combination of a 6x4 grid, 4,096 ways, a Cash Collect system, and four fixed jackpot tiers builds a framework that remains recognizable in both the base game and the free spins.
A central identifying feature is the Big Bounty mechanism. Compared to the series’ predecessors—Big Bounty Gold and Bronco Big Bounty—Captain Bones Big Bounty brings a decisive adjustment: every time 5 scatters appear in the base game, the Big Bounty value increases by 2.5x. In earlier games, this value was only increased by 1x. As a result, the bounty threshold here grows noticeably faster from 10x up to 50x.
This means: the free spin phase gains a significantly sharper profile. Instead of just completing a certain number of free spins, you are effectively working towards a target figure in the base game that determines when the free spin round ends. This target is transparent—10x, 12.5x, 15x, ..., up to 50x—and is clearly signaled by scatter hits.
A second structural pillar is the four fixed jackpots: Mini (15x), Minor (50x), Major (250x), Mega (5,000x). They are incorporated in two ways:
This dual connection ensures that the jackpot structure is not reduced to a single special feature, but extends organically across the entire game. Especially the difference between the jackpot on reel 6 in the base game and jackpots on reels 3–6 in the free spins makes it clear how the bonus phase "opens" the grid and puts a stronger focus on combination possibilities.
Compared to many other pirate slots that work primarily through visual staging, Captain Bones Big Bounty remains deliberately tidy in its graphics. The calm sea backdrop, the lack of a permanent music loop, and the use of targeted animations (Plunder Party, Wheel Bonus Game, jackpot displays) give the slot a rather sober, yet coherent feel. The sound effects primarily serve for orientation: when is something happening, when is a feature starting, when does a cash chain become relevant?
The Plunder Party acts as an additional impulse generator in this structure. Randomly triggered cash clusters always bring at least 6 cash symbols into play and can spontaneously strengthen existing mechanics—especially cash collect and jackpots. In combination with the key symbols in the free spins, which gradually unlock reels and activate additional jackpot positions, a clear arc of tension is created: from building cash chains to unlocking further reels to combining cash and jackpot values.
What distinguishes Captain Bones Big Bounty from many other titles with a free spin bonus is the separation between "number of spins" and "result target". Instead of working through a fixed number of rotations, you are working towards a concrete win threshold (10x–50x) here. The ability to raise this value via Upsizers or repeated 5-scatter hits makes the system flexible. At the same time, the structure remains clear: once the threshold is reached or exceeded, the round ends, and you start again at 10x in the base game.
In terms of similar slots, a comparison with the two predecessors Big Bounty Gold and Bronco Big Bounty is appropriate. All three titles:
Captain Bones Big Bounty stands out due to two points:
Recommended in this thematic environment are, above all, other pirate or treasure hunt slots that rely on multi-way layouts, fixed jackpots, and cash symbols. These titles share a similar combination of:
Captain Bones Big Bounty fits into this group but places its emphasis more strongly on a dynamic target value in the free spins and the interlinking of cash collect, key symbols, and four fixed jackpots. Anyone looking for a structured, clearly readable pirate setting with a distinct focus on mechanics rather than pure visuals will find a consistently executed interpretation of Big Bounty here.
