Bones & Bounty Slot Review
Thunderkick have managed to create something genuinely distinctive with Bones & Bounty. Released in October 2023, this 6-reel pirate-themed slot combines exceptional visual design with innovative mechanics that set it apart in the crowded hold & win market. Rather than relying on theme novelty, Thunderkick has focused on what truly matters: clever feature engineering and engaging gameplay. The result is a game that rewards patient, well-bankrolled players seeking substantial win potential within a high-volatility framework.
Base Game & Features
Bones & Bounty operates across a 6-reel grid with 4,096 ways to win, offering multiple paths to success on every spin. Winning combinations form when three or more matching symbols land from left to right, with the exception of the highest-paying Captain symbol, which forms wins with just two or more symbols. The betting range spans ÂŁ0.10 to ÂŁ100 per spin, accommodating both cautious players and high rollers.
Stacked Respin Wilds
The base game feature comes in the form of Stacked Respin Wilds – wild symbols that occupy 2, 3, or 4 reel positions and land on reels 2 through 6 (never on the leftmost reel). When these wilds land, they lock into place and trigger a respin. The real magic happens when additional stacked wilds land during a respin; each new wild grants an additional respin. Meanwhile, any bonus scatters that land during respins are collected toward filling the bonus meter. This creates a thrilling secondary layer of gameplay that builds anticipation between regular spins.
Bonus Features & Free Spins
Triggering the Cash Bonus Game is straightforward: land three bonus scatter symbols and the bonus round begins. The feature awards an initial 3 free spins, but this is where Thunderkick’s innovation truly shines. The Cash Bonus Game transforms the reel set into a Hold & Win experience unlike anything else on the market, complete with a special 7th reel known as the Ghost Reel.
Ghost Reel Multiplier System
During the bonus round, a seventh reel appears on the far right, the Ghost Reel, which begins with a 2x multiplier. This reel multiplies the value of all symbols present on it, transforming ordinary wins into substantially larger payouts. As symbols shift right through the reels and reach the Ghost Reel, they’re multiplied by the current multiplier value – a mechanic that creates genuine excitement as high-value symbols approach this special reel.
Shift Feature & Free Spins Reset
The Shift Feature represents the clever heart of the bonus mechanics. Each time a new symbol lands on an empty position, the free spins counter resets back to 3, and all current symbols shift one position to the right. This rightward shift brings symbols closer to the Ghost Reel, progressively increasing their multiplied values. The Shift Feature can retrigger indefinitely, theoretically allowing the bonus to continue as long as new symbols keep landing in empty positions. This mechanic breathes new life into the hold & win formula, offering genuine strategic depth alongside the excitement of potential progression.
Cash Symbols & Persistent Payouts
The Cash Bonus Game features special symbols that determine the ultimate payout. Cash Coins carry multiplier values of 1x, 2x, 3x, 5x, and 10x, and notably, these symbols can stack on top of one another, combining their values for cumulative wins. Persistent Payer symbols (carrying 1x, 2x, or 3x values) function differently – when they reach the Ghost Reel, they add their value to all other symbols currently on the board, including other Persistent Payers, creating exponential growth potential.
Multiplier Cash symbols (1x, 2x, 3x values) serve a dual purpose: they increase the Ghost Reel’s multiplier by their own value before transforming into Cash Coins, effectively amplifying all subsequent symbols that reach the Ghost Reel. At the end of the bonus round, all Cash symbols are summed together and applied to the final win. Pay line wins don’t apply during the bonus – the focus is entirely on holding and accumulating cash value.

Bonus Buy & Ante Bet
For players outside UKGC-regulated jurisdictions, Thunderkick offers a Bonus Buy feature priced at 100x your stake. This allows direct access to the Cash Bonus Game without waiting for three scatters to land naturally. The feature also increases the RTP from the standard 96.16% to 96.50%, providing slightly better long-term value for those utilising this shortcut.
Our Honest Verdict
Rating: 8.0/10
Bones & Bounty stands as one of the finest hold & win implementations on the market. Thunderkick has crafted a game that transcends its pirate theme through genuine mechanical innovation. The Ghost Reel, Shift Feature, and layered modifier system work elegantly together to create a bonus experience that’s both complex enough for seasoned players and accessible enough for those discovering the hold & win format.
