This game blends traditional fruit and gem symbols with a unique “Bonus Combo” mechanic where players collect special coins to fill one of three treasure chests. Each chest unlocks a different version of the Hold ‘N’ Link bonus, featuring everything from respins and extra reels to multiplier frames up to x6. The slot includes four fixed jackpots, with the largest offering a win of 5,000 times the bet. This gameplay loop creates a clear sense of progression, keeping players engaged and eagerly anticipating the next bonus round. The innovative feature set ensures that this game stands apart from the typical slots lineup.

Bonus Features at a Glance
| Feature Name | Description | Trigger / How it Works |
|---|---|---|
| Bonus Combo Coins | Gem symbols with green, blue, and red colors that collect and contribute to the corresponding chests. | These coins land on the reels during any spin and are automatically collected. |
| Hold ‘N' Link Bonus | A special respin round that can be activated in one of three ways, each with a different effect. | The bonus game begins after the player collects three Bonus Combo Coins to fill a chest. |
| Juicy Chest | A version of the Hold ‘N' Link bonus that focuses on providing a stable number of respins. | A player activates the Juicy Chest when the green Bonus Combo Coins fill the corresponding chest. During the bonus, respins are set to 4. |
| Lightning Chest | A version of the Hold ‘N' Link bonus with the potential for boosted payouts. | The Lightning Bonus is activated by collecting the blue Bonus Combo Coins. When active, it randomly adds x3 or x6 multiplier frames to the side reels. |
| Extra Chest | A version of the Hold ‘N' Link bonus that expands the playing field. | Activating the Extra Chest with the red Bonus Combo Coins adds two additional reels to the playing grid during the Hold ‘N' Link feature. |
What are the Main Symbols and Payouts?
The game is built on a standard 5-reel, 3-row layout with 5 fixed paylines. Wins are created by landing three or more matching symbols on a payline from left to right, starting from the leftmost reel. The symbols are a modern interpretation of a classic slots machine. Low-paying symbols are represented by juicy fruits, including cherries, lemons, oranges, and plums. The higher-paying symbols include a double BAR and a watermelon. The highest-paying regular symbol is the fiery “777,” which acts as the wild. This symbol can substitute for all other symbols, except the Bonus Combo Coins, to form winning combinations.
How Does the Hold ‘N' Link Bonus Work?
The Hold ‘N' Link bonus is the central feature of the 3 Chests Bonus Combo slot. This mode is not a typical free spins round; instead, it is a respin bonus where each position on the side reels spins independently. The bonus is triggered when three Bonus Combo Coins of the same color are collected, filling one of the three corresponding chests above the main reels. Once a chest is full, the bonus round starts with a direct payoff. Only coins with payouts or jackpots appear during this bonus round, and the feature ends when no more respins are left. This “collector” system provides a unique twist, as a player's progress toward the bonus is visible and persistent.
“Many players mistakenly believe that bonus features in hold-and-link games are purely random. The key to the 3 Chests Bonus Combo slot is to understand that coin collection is a base-game mechanic that directly influences the bonus trigger. Focus on this progress to manage your expectations and enjoy the game,” says Vlad Hvalov, resident slot expert at Respinix.com.
A Closer Look at the Bonus Chests
Each of the three chests offers a distinct variation of the Hold ‘N' Link bonus, creating different gameplay experiences. The Juicy Chest, activated by green gems, sets the number of respins to 4. This is a straightforward bonus, allowing players to collect cash values or jackpot coins that land on the reels. The Lightning Chest, filled by blue gems, adds a layer of excitement by introducing a random quantity of x3 or x6 multiplier frames. When coins land inside these frames, their values are multiplied before being collected, offering a chance for significant payouts. Finally, the Extra Chest, which is filled by red gems, expands the playing field by adding two additional reels during the bonus round. This increases the total number of positions for coins to land on, boosting the chances of hitting a jackpot or collecting more cash prizes. This multi-tiered system adds a layer of depth to the game.
“The addition of extra reels in the Extra Chest bonus is a game-changer. It creates a domino effect, leading to a much higher concentration of coins on the screen. Knowing this can help you decide which chest to prioritize if you have a choice, which is a rare but valuable insight in these types of games,” advises Vlad Hvalov.
Can Players Win a Jackpot?
Yes, the 3 Chests Bonus Combo slot has four fixed jackpots: Mini (50x bet), Minor (125x bet), Major (500x bet), and Grand (5,000x bet). These jackpots are not awarded randomly; they are tied directly to the bonus game. During the Hold ‘N' Link feature, special jackpot coins can land on the reels, awarding the player with the corresponding prize. The Grand Jackpot of 5,000x the bet is a substantial top prize and provides a clear incentive for a player to seek out the bonus game. The jackpot coin mechanic means that a player is always hunting for these high-value symbols once the bonus is active. The ability to win a jackpot is one of the main attractions of this game, drawing players who enjoy the thrill of a big win.
What is the Volatility and RTP of the 3 Chests Bonus Combo Slot?
The specific RTP (Return to Player) and volatility of the 3 Chests Bonus Combo slot are not officially published by the developer. However, based on the fixed jackpot prizes and the nature of the Hold ‘N' Link bonus, it is reasonable to expect a high-volatility experience. High-volatility slots tend to award less frequent but more significant wins, which aligns with the game's focus on chasing a large jackpot. The gameplay is well-suited for a player with a larger bankroll who is looking for the thrill of a major payout rather than consistent small wins.
Comparative Analysis: 3 Chests Bonus Combo vs. Other Titles
The 3 Chests Bonus Combo game stands out by combining the classic fruit themed slots experience with an intricate bonus system. The game's approach to jackpots and multipliers differs from that of a game like the popular Gates of Olympus free slots which awards its multipliers randomly in the base game. In contrast, this game links its bonus multipliers and jackpot prizes to the Hold ‘N' Link feature, requiring players to build up progress before the bonus round. Another point of comparison is the jackpot mechanics; while Jackpot Blaze free game from Pragmatic Play offers a jackpot wheel, the 3 Chests Bonus Combo slot uses jackpot-specific coins that appear on the reels during the respin bonus, offering a more direct path to a prize. This strategic design of the bonus round gives it a distinct feel, making it a viable alternative for a player who enjoys a more structured chase for big wins.
Three Chests: A Brief History
- The concept of three chests as a reward system has roots in classic video games, where players would be presented with a choice of three treasure chests, each containing a different prize. This slot brings that element of choice and anticipation to the reels.
- The use of gemstones (Green, Blue, Red) for each chest is a direct nod to classic adventure and treasure slots, where different colored gems often represented different levels of rarity and value.
- The fixed jackpot values are a clever way to appeal to players who prefer a clear, predictable target instead of a progressive jackpot that changes over time.
Final Verdict: Is this Slot Worth a Try?
The 3 Chests Bonus Combo slot from NetGame is a well-designed game that successfully bridges the gap between classic fruit machines and modern bonus mechanics. Its central Hold ‘N' Link feature, with the three distinct chest variations, provides a compelling gameplay experience that feels rewarding. While the lack of a published RTP and volatility rating may deter some players, the promise of a 5,000x Grand Jackpot is a strong motivator for others. For a player who enjoys a game with a sense of progression and a clear target to work toward, this slot offers an engaging and visually appealing journey into a world of sparkling gems and bountiful rewards. The innovative bonus system is a testament to NetGame's ability to create a game that feels both familiar and fresh.
