How Does the Expanding Grid and Cluster Pays System Work?

The Cubes slot operates on a Cluster Pays mechanic, where wins are formed by landing a group of 5 or more identical colored cubes that are connected horizontally or vertically. After a winning cluster is formed and paid, the game round doesn't end; instead, the Expanding Grid is activated. Unlike games with fixed grids like Hacksaw's own Le Bandit slot, the play area here is dynamic.

For each new cluster formed during a spin, the grid expands by one row and one column, growing from its initial 5×5 size up to a maximum of 11×11. This expansion creates more space for additional cubes to land, potentially connecting to existing clusters or forming new ones. The process continues within the same spin until no new connections are made. This creates a chain reaction where a modest starting win can snowball into a full-screen event, offering a different kind of satisfaction than traditional reel-based slots with classic themes.

The Middle Multiplier: The Core of Your Winnings

The key to significant wins in the base game is the Middle Multiplier. The centermost cube on the grid is marked with an ‘X' and holds a multiplier value. When this cube is part of a winning cluster, its multiplier is applied to the payout for that cluster.

The mechanic's brilliance lies in how the multiplier grows. The value increases by the number of cubes included in the winning cluster. For example, if you form a 7-cube cluster that includes the middle ‘X', your win is not only multiplied, but the multiplier's value for the next potential connection in that spin sequence increases by 7. The maximum multiplier that can be reached is 22x. This feature turns the center of the grid into the most valuable territory, forcing a strategic focus on not just cluster size, but cluster position.

Vlad Hvalov's expert take: “Don't just chase the biggest cluster. A small 5-cube win that includes the center ‘X' is often the spark that ignites a much larger, multiplier-boosted cascade. Position beats size in the early stages.”

How Do You Unlock the Free Spins Bonus Round?

The Free Spins feature in the Cubes demo is triggered in a non-traditional way. Instead of landing scatter symbols, you must form five or more winning clusters of different colors within a single game round. Once activated, the game presents all the different colored cubes that formed your winning clusters, and you pick one to reveal a number of free spins, up to 10.

During the bonus, two critical things change. First, the size of the grid at the moment of the trigger becomes locked for the duration of the free spins. Second, the color of the final cluster that triggered the round becomes your “sticky” color. Any wins formed with this color will remain on the grid until the round ends. This transforms the objective from making any cluster to building one massive, screen-filling cluster of your chosen color.

The Elusive Color Blast: Chasing the 2,500x Prize

The ultimate goal of the Free Spins round is to trigger the Color Blast. This is an instant prize of 2,500x your bet that is awarded if you manage to build a sticky cluster of 70 or more cubes. Achieving this requires a combination of a large starting grid (ideally 9×9 or 11×11 from the triggering spin) and favorable cube drops during the 10 spins. It is the game's built-in jackpot and the primary source of its maximum win potential.

What is the Volatility and RTP of the Cubes Slot?

The Cubes slot game is defined by a theoretical Return to Player (RTP) of 96.35% and operates on a medium-high volatility mathematical model. The RTP is a solid figure, sitting comfortably above the industry average.

The medium-high volatility is the true engine of the gameplay experience. It means that the game pays out less frequently on average, but the chance of hitting big wins in a short amount of time is higher. This places it in a similar risk category to other high-potential titles like the futuristic Money Train 3. In the Cubes demo, this translates to periods of smaller, maintenance-level wins, punctuated by explosive chain reactions or a lucrative Free Spins round. The maximum win is capped at 3,000 times the bet.

Vlad Hvalov's advice: “Treat the Cubes demo like a marathon, not a sprint. The game's math is designed to test your patience between big events. Use the free-play mode to find a bet level that can withstand 200-300 spins; that’s the real way to understand its rhythm.”

The Patience Paradox of Cubes

On the surface, Cubes appears to be a simple, fast, and almost meditative puzzle game. But this simplicity is deceptive. The core of the game is a paradox: its minimalist design suggests a casual experience, yet its high-volatility math demands the patience and bankroll discipline of a seasoned player. The game's rhythm is not a steady beat but a slow build-up to a sudden crescendo. For every spin that results in a screen-filling, multiplier-boosted win, there are dozens that yield nothing. This makes it a poor fit for players seeking consistent, small-to-medium rewards. It's built for the player who understands that the potential for a 3,000x win is paid for with periods of inactivity.

Visuals, Sound, and the POCKETZ Mobile Experience

Cubes is a flagship title in Hacksaw Gaming’s POCKETZ series, a line of games designed with a mobile-first philosophy. The user interface is clean, buttons are large, and the game plays flawlessly in portrait mode, making it perfect for one-handed gaming. This focus on a streamlined mobile experience is a core part of its appeal and a welcome departure from overly complex slots that feel cluttered on a smaller screen.

The aesthetic is intentionally simple, employing a Retro-style visual design with flat, bold colors and basic animations. There's no distracting narrative or characters. The sound design complements this, with subtle clicks and satisfying electronic tones that escalate as the grid expands and wins accumulate. It’s a design choice that serves the gameplay, ensuring the player's focus remains squarely on the mechanical puzzle unfolding on the screen.

What If… Every Cube Held a Multiplier?

Honestly, I was playing the Cubes demo and a thought struck me. What if the game's design took a completely different path? Imagine this: instead of a single Middle Multiplier, every cube that was part of a winning cluster revealed a +1 value. All these values would then be summed and applied as a global multiplier for that entire spin sequence. This single change would flip the game on its head. Suddenly, the strategic importance of the grid's center would vanish. The new goal? Create the largest, most sprawling cluster possible, regardless of its position. It would become a game of pure surface area, a frantic rush to cover the screen, rather than a tactical play for the valuable center square. Would it be better? I don't know. Different, for sure.

The Synergistic Engine: Grid Expansion and Sticky Spins

There's a hidden synergy here that most players miss. It's the powerful connection between the base game's grid expansion and the fixed grid in the Free Spins. They seem like separate phases of the game, but they are deeply linked. Triggering the free spins is one thing, but triggering them after a massive cascade in the base game that has expanded the grid to 9×9, 10×10, or even the full 11×11 is a complete game-changer. Starting your 10 free spins on a larger playing field dramatically increases the surface area available for your sticky color to land and connect. This makes the 70-cube Color Blast move from a distant dream to a tangible possibility. The base game isn't just a waiting room for the bonus; it's the launchpad that determines the bonus's true potential.

Unearthing the Code: Hidden Truths of Cubes

1. Anti-Clutter Philosophy: Cubes was an early showcase of Hacksaw's POCKETZ series, which was a direct response to the industry's trend of increasingly complex and visually noisy slots. The goal was to prove that compelling mechanics could stand on their own.
2. Equal Symbol Value: A subtle but critical design choice is that all six colored cubes have the exact same payout value. This removes the frustration of landing a large cluster of a “low-paying” symbol, a common annoyance in many other Cluster Pays games like the fruit-filled Sugar Rush 1000.
3. The Trigger Condition: The trigger for Free Spins—landing five different color clusters—is statistically challenging. It ensures that the bonus round feels earned and maintains its high value, contributing significantly to the game's high volatility.

How Does Cubes Compare to Other Modern Grid Slots?

In the landscape of modern grid slots, Cubes carves out its own niche. While a game like Pragmatic Play's Sweet Bonanza bombards players with tumbling reels and random global multipliers, Cubes takes a more structured, architectural approach. It avoids the random multiplier drops seen in Gates of Olympus 1000, instead making the player build the multiplier actively through cluster size and position.

Compared to another Hacksaw Gaming title like the Wild West themed Wanted Dead or a Wild, Cubes is the polar opposite. It showcases the developer's incredible range. For players who enjoy unconventional grid mechanics, Pirots 2 by ELK Studios offers a completely different symbol collection system, while Push Gaming's Retro Tapes offers high-volatility cluster action with more modifiers. Exploring the diverse collection of online demo slots reveals just how unique the Cubes game is.

Cubes vs. Cubes 2: An Evolutionary Leap?

Hacksaw Gaming released a sequel, Cubes 2, which builds upon the original's foundation. The core concept remains, but the sequel introduces Corner Multipliers. In addition to the Middle Multiplier, the ‘X' symbols in the four corners of the grid also apply multipliers to wins, with their values adding together. This significantly increases the action and potential across the entire grid, not just the center. While the original Cubes is a game of precision focused on the central point, Cubes 2 is a more explosive and arguably more volatile experience. The sequel feels like a direct response to players who loved the core idea but wanted even more potential packed into every spin.

Final Thoughts: Why the Cubes Demo is a Must-Play

So, what's the final word? The Cubes slot is a brilliant piece of minimalist design. It's a statement game that proves you don't need epic themes or a dozen complicated features to create a compelling and high-potential slot. It successfully translates the satisfying feeling of solving a puzzle into a gambling format.

However, its high volatility and unique rhythm are not for everyone. This is a game for the patient player, the strategist who enjoys seeing a plan come together. It's a perfect fit for mobile gamers who appreciate clean design and for anyone looking for a break from the noise of typical Vegas-style slots. It’s a game that fits perfectly into Hacksaw Gaming’s portfolio by being a complete outlier—a quiet, confident title that relies on raw mechanical power rather than thematic flair. Trying the Cubes free play is the only way to truly appreciate its unique architectural approach to slot design.
