Chests of Gold: Power Combo (All41 Studios) Slot Review

Chests of Gold Power Combo: Slot Overview 

Released on March 28, 2023, Chests of Gold Power Combo is a high-volatility online slot from All41 Studios in partnership with Games Global. It serves as a follow-up to the developer’s earlier release Kings of Crystals, though it’s closer to a thematic reimagining than a brand-new concept. This time, the crystal motif is swapped for a medieval adventure set in lush woodlands, where players, bow in hand like a Robin Hood figure, hunt for treasure-filled chests that unlock the game’s three main bonus features. 

Played on a 5-reel, 4-row grid with 40 fixed paylines, the game offers a 96.40% RTP, a hit frequency of 38.79%, and a max win potential of 11,650x the bet. With bet limits ranging from €0.20 to €20, the slot is accessible to a wide range of players. The central hook lies in its “Power Combo” mechanic, where multiple features can be triggered simultaneously, ramping up the excitement.

Design and Graphics 

Chests of Gold Power Combo takes place in a serene yet adventurous medieval setting. The reels are framed by wooden beams against a backdrop of lush green forests and castle towers. It’s a world that feels peaceful when the reels are stationary, complete with soft lighting and detailed foliage, yet transitions into an atmosphere of urgency and drama when bonus rounds trigger.The symbols are cleanly rendered with a semi-realistic style. Low-value icons are stylized card ranks (9–A) painted in gold, while high-value symbols include thematic imagery such as a quiver of arrows, bags of coins, and character portraits—a stern male figure, a mysterious lady, and a potential antagonist. These premium symbols are worth between 2.5x and 5x the bet for a five-of-a-kind combination. 

The Wild symbol, appearing only on reels 2, 3, and 4, stands out with its bright target design, substituting for all symbols except scatters and coins. Overall, the visual style balances realism with an inviting fantasy flair, drawing players into its Robin Hood-inspired treasure hunt.

Gameplay Mechanics 

The core action unfolds on a 5×4 reel set with 40 fixed paylines, meaning players cannot adjust the number of lines in play. Wins form from left to right, requiring at least three matching symbols on consecutive reels. 

Low-Value Symbols (9–A) pay 0.75x the bet for five of a kind. 

High-Value Symbols pay between 2.5x and 5x the bet for five of a kind. 

Wild Symbols substitute for regular pay symbols and appear only on reels 2–4. 

Scatter Symbols are represented by three different colored chests—red, green, and blue—each linked to a distinct bonus feature. 

Coin Symbols appear during the jackpot feature and can award cash prizes or contribute toward jackpots. 

One of the standout gameplay features is the ability to trigger multiple bonus features at once. If more than one scatter color lands in a single spin, their respective features can run simultaneously, significantly boosting winning potential.

Sound and Music 

The audio design in Chests of Gold Power Combo matches its medieval fantasy setting perfectly. When the reels are idle, you’ll hear the gentle rustle of leaves, distant bird calls, and a soft drumbeat—sounds that evoke a peaceful woodland scene. 

When the reels spin and especially when bonuses activate, the soundtrack shifts to a more urgent, adventurous score, with rising percussion and triumphant melodies. This dynamic music shift enhances the sense of progression from calm exploration to high-stakes treasure hunting. Symbol hits and scatter triggers are punctuated with satisfying clinks, coin jingles, and bowstring-like sound effects, reinforcing the Robin Hood-inspired theme.

Bonus Features 

The Power Combo mechanic forms the heart of the game’s bonus action, allowing the three primary features—each tied to a chest scatter—to run individually or in combination.Red Chest – Free Spins with Nudging Wilds

Triggers 5 free spins on an expanded 7-row, 100-payline grid. 

When a wild lands, it nudges to fill the entire reel. 

Red chests can retrigger additional free spins. 

This feature focuses on coverage wins, with nudging wild reels often leading to multiple high-value combinations. 

Green Chest – Free Spins with Jackpot Collection

Awards 10 free spins where coins can reveal either instant cash prizes (1x or 10x the bet) or letters that contribute to one of four jackpots: 

Grand Jackpot: 10,000x (G, R, A, N, D) 

Major Jackpot: 500x (M, A, J, O, R) 

Minor Jackpot: 50x (M, I, N, O, R) 

Mini Jackpot: 25x (M, I, N, I) 

Completing a letter set awards the corresponding jackpot. 

Multiple jackpots can theoretically be won in the same round. 

Blue Chest – Free Spins with Line Multiplier

Grants 5 free spins. 

Each spin carries a random line multiplier of x2, x3, x5, or x10. 

Blue scatters during the feature award additional free spins. 

Best suited for stacking multipliers on big line wins. 

Power Combo Triggers

If two or three different chest types land together, their features play simultaneously. 

For example, a Red + Green trigger would give nudging wilds and jackpot collection in the same spins, while all three combined deliver the ultimate feature mash-up. 

Buy Feature

Available in certain jurisdictions, the Buy Feature lets players purchase:Single Feature from 20x bet. 

Double Feature from 55x bet. 

All Three Features for 110x bet. 

This is a high-cost option aimed at players seeking immediate access to bonus action without waiting for natural triggers.

Betting Options and Payouts 

The game accommodates various bankrolls with a bet range from €0.20 to €20 per spin. Combined with the high volatility, this means players can tailor their risk levels while still chasing significant payouts. 

Key statistics: 

RTP: 96.40% (other versions may vary down to 86.7%) 

Hit Frequency: 38.79% 

Max Win: 11,650x the bet 

Volatility: High 

Paylines: 40 fixed in base game, 100 in Red Chest feature 

The maximum win potential is most realistically reached through Power Combo triggers that overlap multipliers, nudging wild reels, and jackpot collection—all running in the same bonus sequence.

Conclusion 

Chests of Gold Power Combo is a visually polished and mechanically versatile slot that builds on the framework of its predecessor, Kings of Crystals, while shifting to a Robin Hood-inspired treasure hunt theme. Although the core structure will feel familiar to players who experienced the earlier title, the medieval setting, character art, and chest-triggered Power Combo system give it its own charm. 

The ability to trigger multiple bonus features at once is the game’s standout selling point, offering a level of unpredictability and synergy that can lead to thrilling moments. The Buy Feature adds another layer of control for players who prefer to skip straight to the action, though the high cost makes it best suited for those with bigger bankrolls. 

On the flip side, the slot doesn’t reinvent the wheel. If you didn’t enjoy Kings of Crystals, you may find this too similar, albeit with a fresh coat of paint. Still, the combination of 96.40% RTP, high volatility, and a max win of 11,650x ensures it has the potential for dramatic payouts. 

For fans of fantasy-themed slots, medieval adventures, and feature-stacking gameplay, Chests of Gold Power Combo is worth exploring—especially if you enjoy chasing layered bonuses and high-risk, high-reward action.
