Bone Raiders (Relax Gaming) Slot Review

Bone Raiders: Slot Overview 

Bone Raiders is a delightfully offbeat online slot from Relax Gaming, mixing quirky visuals, a dual-phase gameplay structure, and a coin-accumulation bonus feature. The name might suggest something macabre—perhaps black-market fossil deals—but what players actually get is a charming band of skeletal adventurers raiding coins with medieval tools and mystical devices. The game borrows the split gameplay design seen in previous Relax hits like Marching Legions and Mega Heist, starting with a standard grid-based base game before shifting into an expansive bonus round where the true treasure hunting begins. 

The base game is played on a 5×3 grid with 243 ways to win, while the bonus game adopts a 3×3 expanding to 7×7 layout, offering a dramatic shift in mechanics. With a medium-high volatility profile and a respectable RTP of 96.1%, Bone Raiders delivers a balanced mix of charm, suspense, and solid win potential. The maximum win is capped at 10,000x, offering plenty of incentive for raiding beyond the surface fun.

Design and Graphics 

Relax Gaming clearly had fun crafting Bone Raiders, presenting a top-down view of a fortress courtyard, complete with cracked stone tiles, treasure chests, cute skeletons, and a surrounding moat. It has an aesthetic that will remind players of previous Relax releases like Snake Arena and Marching Legions, though this time with a more whimsical, fantasy-leaning tone. The design cleverly distinguishes between the game’s two phases: the sunlit, exterior grid of the base game, and the darker, stone-walled chamber of the bonus round.The attention to detail is commendable. From animated skulls peeking out from the moat’s corners to visual flourishes like stone symbols collapsing into dust during respins, everything reinforces the adventurous theme. Even the bonus trigger screen, with its illustrated feature explanations (Magic Staff, Bomb, Cannon, Compass), is lovingly crafted.

Gameplay Mechanics 

At its core, Bone Raiders uses a pay ways system—any combination of three or more matching symbols starting from the leftmost reel results in a win. There are no wild symbols in the base game, but what it lacks in traditional substitutes, it makes up for with the respin multiplier mechanic. Every win triggers a respin, and each successive win during this sequence doubles the multiplier (x1, x2, x4, etc.), increasing win potential. The sequence continues until no further wins occur. 

The base symbols include four low pays—diamond, club, heart, and spade—each paying 0.3x for five of a kind, and four character symbols—skeletal pirates, knights, and more—paying up to 100x the stake for five matches. Though base game wins can feel modest, they offer momentum through the respin mechanics. 

The transition to the bonus round marks a major mechanical shift. Players must land 3 scatter symbols on reels 2, 3, and 4 to trigger it, and once they do, they’re taken to a whole new arena of gameplay focused on coin collection, blockers, and feature symbols.

Sound and Music 

Bone Raiders leans heavily on ambient sound design, favoring quiet, moody tones in the base game that complement the fortress setting. The soundscape is filled with subtle percussion, creaking wood, and occasional gusts of wind—all evoking the feeling of exploring a desolate castle yard. When respins occur, a satisfying swoosh accompanies each collapse, with audio cues reinforcing the increase in multiplier intensity. 

In the bonus round, the audio becomes more dramatic and upbeat, matching the increase in visual action. When feature symbols like Bombs or Cannons activate, satisfying bursts of sound accompany their effects, highlighting the destructive yet fun chaos they unleash.

Bonus Features 

Bone Raiders’ bonus round is the heart of the slot, and it’s where the game truly stands out. Upon triggering, the grid changes to a 3×3 layout within a 7×7 blocked framework. The goal: unlock more space, destroy blockers, collect coins, and boost values.Feature Symbols 

Triggering scatter symbols turn into feature symbols, each with a unique effect: 

Magic Staff: Targets a random symbol 3 to 7 times. 

Bomb: Hits the central tile and surrounding positions in a 3×3 radius. 

Cannon: Fires at 1 to all tiles at random. 

Compass: Targets entire patterns like rows, columns, or diagonals. 

These feature symbols destroy blockers, allowing the active play area to expand. If a destroyed tile contains a coin, its value is doubled. After activation, each feature symbol transforms into a coin with a value of 1x the bet. 

Bonus Round Mechanics 

The bonus begins with 2 spins, which reset every time a feature symbol lands. Additionally, every 20 blockers destroyed adds +1 to the reset spin count, up to a maximum of 4 spins. It’s a compelling loop of destruction and expansion, with each new symbol offering the chance to chain feature triggers and fill the grid with high-value coins.

Betting Options and Payouts 

Bone Raiders accommodates a wide range of players with its betting limits from €0.10 to €100 per spin, making it accessible to casual players while still being attractive to high-rollers. The base game may not deliver frequent massive hits, but the respin mechanic helps extend gameplay and preserve bankrolls through repeated, incrementally better wins.The maximum win of 10,000x the stake is achievable primarily in the bonus round, where strategic feature symbol deployment and blocker destruction can turn the tide in your favor. Additionally, players have the option to buy the bonus for 70x the base bet, which has an elevated RTP of 96.5%. This provides a reliable shortcut for those eager to jump into the real action.

Conclusion 

Bone Raiders is a cleverly designed and well-balanced slot that blends old-school mechanics with new-age execution. The base game, while simple, is elevated by the respin multiplier, adding anticipation to every small win. The bonus game is a fully fleshed-out coin-collecting spectacle, where strategy, destruction, and luck combine into a highly engaging experience. It’s the kind of slot that takes a little patience to unlock its full potential but rewards persistence with moments of thrilling chain reactions and big payouts. 

Visually polished, mechanically engaging, and stuffed with charm, Bone Raiders stands as a strong example of Relax Gaming’s creative direction in 2024. The theme may be light-hearted, but the math model is serious, capable of delivering wins up to 10,000x in a tightly woven framework of risk and reward.
