Skulls and Souls Bonanza Coin Grid by Maxxi Labs brings the colourful atmosphere of Mexico’s Day of the Dead celebration to a feature-rich online slot. Decorated sugar skulls, marigold flowers, mariachi-inspired details, and festive instruments create a distinctive setting where traditional Mexican imagery meets modern casino gameplay. Rather than relying solely on standard reel combinations, the game combines a 5×5 layout, 40 paylines, a mirrored Coin Grid, and several Hold & Win bonus modes. Released on September 30, 2026, the slot features an advertised RTP of 96%, very high volatility, and a maximum win of 5,000x the bet. Its main attraction is the interaction between coin collection, grid completion, respins, and persistent boosters. Players can pursue cash prizes by completing horizontal, vertical, and diagonal patterns, while special jackpot coins add another layer to the bonus experience. The Mexican theme provides more than a decorative backdrop. Sugar skulls and festive symbols establish the game's identity, while the Coin Grid and Hold & Win features give each session a progression-based structure. The result is a slot designed for players who enjoy detailed bonus mechanics, jackpot opportunities, and the potential for substantial but unpredictable payouts.

Gameplay: A 5×5 Grid with 40 Paylines
Skulls and Souls Bonanza Coin Grid uses a five-by-five playing area with 40 paylines. The base game combines conventional symbol combinations with special coin mechanics that can lead into more complex bonus rounds.
The central objective is to land winning combinations while building progress toward the Coin Grid and Hold & Win features. Wild symbols help complete ordinary wins, while Scatter symbols provide access to Free Spins. Coin symbols serve a different purpose: they contribute to the collection mechanics and can activate dedicated bonus rounds.
This combination creates two distinct gameplay paths. Regular wins come from the slot's symbol combinations, while feature-based rewards depend on collecting coins, completing grid patterns, activating boosters, or securing jackpot symbols.
The 40-payline structure provides a familiar foundation, but the additional grid system makes the game more involved than a conventional themed slot. Players need to understand not only the value of the symbols but also how individual coins contribute to the larger bonus sequence.
Main Bonus Features in Skulls and Souls Bonanza Coin Grid
1. Super Stacks
Super Stacks can expand the presence of selected symbols by adding stacked versions across the reels. In the base game, eligible symbols exclude Wilds, Scatters, and Coins. During Free Spins, the feature is restricted to Wild and Coin symbols.
This distinction matters because stacked symbols can increase the number of positions involved in a spin, while the bonus-game version focuses on two symbol types connected to winning combinations and coin collection. Super Stacks therefore support both standard gameplay and the slot's special-feature economy.
2. Power Mode
Power Mode enhances the coin-collection process and can trigger during the base game. When activated, it awards a free Coin symbol that is held by the Coin Collect meter. It also reduces by one the number of coins required to advance the meter or trigger Hold & Win.
With Power Mode active, five or more Coin symbols can trigger Hold & Win, while three or four Coins contribute to the meter's progression. This adjustment creates an additional route into the bonus and can make coin-heavy spins especially important.
3. Coin Grid Feature
The Coin Grid is one of the game's defining mechanics. Cash Coins and Jackpot Coins populate a dedicated mirrored grid, where completing specific patterns generates rewards.
The qualifying patterns include:
- Horizontal lines: Complete a row of Coin symbols to win the associated cash prize.
- Vertical lines: Fill a column to create another potential winning set.
- Diagonal lines: Connect the relevant corner-to-corner positions to complete a diagonal pattern.
- Multiple completed sets: A single spin can complete up to four qualifying sets, increasing the number of potential rewards from one grid interaction.
Cash values from intersecting coins can contribute to the prize for each completed set. Only Coin symbols that form part of a winning set are removed, allowing other coins to remain on the grid and potentially contribute to later combinations.
4. Coin Grid Fixed Jackpots
The Coin Grid also features four fixed jackpot tiers. Their advertised values are:
- Grand Jackpot: 5,000x the bet
- Major Jackpot: 500x the bet
- Minor Jackpot: 50x the bet
- Mini Jackpot: 15x the bet
Completing a winning pattern containing at least one Jackpot Coin awards the corresponding jackpot. The grid can hold up to one Coin from each jackpot tier at a time.
The Grand Jackpot establishes the game's maximum advertised win, although reaching it depends on the relevant feature conditions and is not guaranteed. The fixed jackpot structure gives the Coin Grid a clear progression of prizes, from the Mini tier to the 5,000x top award.
5. Hold & Win
Hold & Win is another major component of the slot. Landing six or more Coin symbols triggers the feature, which can activate in either the base game or Free Spins.
The feature begins with three free respins. Triggering Coins remain in place, while other positions respin. Any additional Coins that land are held, and the remaining respin count resets to three. The round ends when no respins remain or every available symbol position is filled.
Cash Coins display random values that can be collected at the end of the feature. Jackpot Coins have countdowns that progress with each spin; qualifying jackpot symbols that complete their countdown award their associated prizes when the round ends.
The combination of locked symbols, resetting respins, and coin values creates a collection-based bonus that can develop over several spins.
6. Three Hold & Win Modes
Filling the Hold & Win meter to the relevant level allows access to three enhanced modes:
- Max Mode: Starts Hold & Win with three additional active rows, expanding the available playing area.
- Multiplier Mode: Adds three active rows and guarantees a Persistent 2x Multiplier Booster Coin.
- Collect Mode: Adds three active rows and guarantees a Persistent Cash Collect Booster Coin.
These modes offer different approaches to the bonus. Max Mode emphasises additional space, Multiplier Mode focuses on increasing coin values, and Collect Mode centres on gathering cash rewards into a combined total.
7. Hold & Win Booster Coins
Several booster symbols can modify the feature's outcome:
- Persistent Cash Collect: Collects the combined value of Cash Collect Booster Coins and Hold & Win Cash Coins on every spin.
- Cash Collect: Collects the value of previously landed Persistent Cash Collect Booster Coins and Hold & Win Cash Coins.
- Persistent 2x Multiplier: Randomly doubles the values of up to four Hold & Win Cash Coins on every spin.
- 2x Multiplier: Randomly doubles up to four Hold & Win Cash Coins.
- Unlock: Opens one additional row per symbol, up to three extra rows.
- Extra Chance: Awards one additional free respin per symbol.
These boosters introduce several interacting ways to increase the value of the feature. Their effects differ, so the outcome depends on which symbols land and how the bonus develops.
8. Free Spins
Landing three or more Scatter symbols triggers 10 Free Spins. During this round, Wild or Coin symbols are Super Stacked on every free spin.
The bet and paylines remain the same as those used for the triggering spin. The Super Stacks mechanic gives the bonus a distinct character, combining opportunities for conventional wins with additional chances to land Coins and interact with the game's collection features.
9. Wilds, Scatters, and Regular Symbols
Wild symbols substitute for other symbols to complete winning combinations, except for Scatters and Coins. Scatter symbols can appear in any position and provide access to Free Spins.
The regular paytable separates symbols into two broad groups:
- Premium symbols: Five skeletal and masked characters, paying between 2.5x and 5x the bet for five matching symbols.
- Lower-paying symbols: A Mexican vihuela-style guitar, sombrero, tequila bottle, and sugar-skull maracas with crossed bones, paying between 1.6x and 1.8x the bet for five matching symbols.
These figures describe the reported five-symbol awards; actual payouts depend on the applicable paytable and game configuration.
Buy Feature Options
Where the casino enables bonus purchases, players can access four Hold & Win options at the following advertised costs:
- Standard Hold & Win: 50x the bet
- Max Mode: 95x the bet
- Multiplier Mode: 120x the bet
- Collect Mode: 200x the bet
The purchase price is separate from the ordinary spin stake and can represent a substantial commitment. Buying a feature does not guarantee a profitable outcome or the maximum jackpot. Availability may also be restricted at certain betting levels or in particular jurisdictions.
Final Verdict
Skulls and Souls Bonanza Coin Grid by Maxxi Labs combines Mexico's vibrant Day of the Dead imagery with a feature-heavy slot built around coin collection and jackpot progression. Its 5×5 layout and 40 paylines provide the foundation, while the mirrored Coin Grid, Power Mode, Hold & Win, and three specialised bonus modes create additional layers of gameplay.
The advertised 96% RTP and 5,000x maximum win are notable specifications, but the very high volatility makes outcomes unpredictable. The game's main appeal lies in its interaction between grid completion, respins, multipliers, and collecting mechanics rather than in conventional reel wins alone.
For players who enjoy Mexican-themed slots with detailed bonus systems and fixed jackpots, Skulls and Souls Bonanza Coin Grid offers a distinctive option. Those who prefer simpler mechanics or lower volatility may want to consider its complexity and risk profile before playing.
