Grid Slots: Key Takeaways
- Grid slots replace traditional reels and paylines with large, open grids where wins form through connected symbol clusters.
- A Cluster Pays mechanic rewards groups of five or more matching symbols touching horizontally or vertically.
- Typical layouts are 7×7 or 8×8, allowing multiple winning combinations per spin.
- Scatter Pays slots differ by paying for matching symbols anywhere on the grid, without adjacency.
- Leading developers such as Play’n GO, NetEnt, Pragmatic Play, Relax Gaming, and Hacksaw Gaming continue to expand the format.
- Grid slots blend slot gameplay with puzzle-style design, creating fast-paced, chain-reaction wins.
What Are Grid Slots?
Grid slots are online slots that swap traditional reels and paylines for a larger grid layout and the Cluster Pays mechanic. Instead of lining up symbols across fixed lines, wins come from clusters of five or more matching symbols that touch horizontally or vertically. In addition, most grid slots have a high volatility, offering potentially large payouts but requiring players to endure dry spells.
Most grids are 7×7 or 8×8, giving plenty of room for symbols to land and connect. The key feature in these games is the cascading wins (or Avalanche) mechanic. When a cluster hits, the winning symbols disappear, and new ones drop in to take their place. This can trigger a chain of back-to-back wins from a single spin, keeping the gameplay quick and engaging.
Unlike traditional slots, which require winning combinations to start from the leftmost reel, grid slots allow clusters to form anywhere on the grid, offering a different style of play.
First introduced by studios like NetEnt and refined by Play’n GO, the grid slot format appeals to players looking for more interaction and variety than standard payline slots.
Heads Up: Grid slot games generally have high volatility—be prepared for long waits and big rewards!
How Do Grid Slots Work?
Grid slots redefine the structure of a slot game. Instead of reels that spin, symbols fall or “tumble” into a grid, creating a more continuous flow of play. Each spin or cascade can be considered a turn, with every turn producing a new result. Here’s how the main parts work.
The Grid Layout
The layout follows some standard rules:
- Typically 7×7 or 8×8 (sometimes larger or smaller, depending on the game)
- Symbols drop from above instead of spinning
- The layout resembles a puzzle board rather than reels
Cluster Pays Mechanic
| No paylines; wins come from clusters of connected matching symbols | Clusters usually require at least five symbols |
| Only horizontal or vertical connections count (not diagonals) | Payouts increase with the size of the cluster |
Cascading Wins
Here’s how the wins work:
- Winning symbols are removed after each win
- New symbols fall into place, possibly forming new clusters
- Cascades continue until no new wins form
These elements make grid slots feel fluid and dynamic, with each spin capable of producing several consecutive wins.

Why Play Grid Slots
Grid slots offer a break from the routine of payline slots. The gameplay feels more open and interactive, often leading to chain reactions that can build momentum and tension.
The core appeal lies in how a single paid spin can initiate a winning cascade sequence. This eliminates the restriction of fixed paylines, instead awarding wins for adjacent groupings of symbols anywhere on the expanded grid.
Furthermore, many games include extra features such as multipliers, symbol-collection meters, or special wild modifiers that trigger after multiple cascades. This adds progression and variety, making each spin feel part of a larger sequence.
Players who enjoy puzzle-like mechanics and fast, chain-based wins often gravitate toward grid slots.
New Grid Slots Released in 2025
Developers of online slots continue to experiment with the format, adding new twists and bonus features. The games listed below are some of the top new grid slot releases for 2025 that you can test among many free slots this year.
Pumped Up
Released on October 14, 2025, Pumped Up is one of the latest grid slots by Indigo Magic. This neon party is full of dance beats and some great winning opportunities. It is a Cluster Pays mechanic with 5 reels. The max win is 6,997.7x your stake with high volatility. The grid slot also has an RTP of 96.02%–just slightly above average. You also get to enjoy over 10 free spins and between 2x and 20x multipliers.
Oracle of Gold
Travel to Ancient Greece with the Oracle of Gold online grid slot by Pragmatic Play. A Greek temple with marble columns and the Oracle always present by the grid set a mystical atmosphere. The very high volatility, paired with 96.55% RTP, means wins don’t come often but are sure to be explosive. If you are lucky, you will also get to enjoy between 10 and 20 free spins and a max win of 2,800x the bet.
Jack Hammer™ 4: Chasing the Dragon
If you are a fan of detective stories with great visuals, NetEnt’s Jack Hammer™ 4: Chasing the Dragon is one of the best grid slots for you. The comicbook-styled slot is set in Chinatown and is played on a 6×6 grid. The online slot offers 6 bonus features, up to 100x multiplier, and a solid max win of 10,000x your bet.
Reactoonz 100
Followed by the success of Reactoonz and Reactoonz 2, Play’n GO is here with adorable aliens in Reactoonz 100. This time around, the RTP is 96.2%, the volatility is very high, and the 100 max win is 10,000x. The 7×7 grid is huge and provides a lot of colourful visuals—it’s aliens and spacecrafts galore.
Gonzo’s Quest 2: Return to El Dorado
NetEnt’s release from September 2025, Gonzo’s Quest 2: Return to El Dorado, is visually stunning with a pastel colour palette and superbly done symbols. The shifting 6-reel grid offers up to 262,144 paylines! Several bonus features make the gameplay exciting, and the 15,825x max win doesn’t hurt. The high volatility prevents wins from appearing often, but once they hit, they are impressive.
How to Win at Grid Slots
With standard video slots, wins are created by landing matching symbols on successive reels starting from reel one. In grid slots, wins come from clusters of adjacent matching symbols rather than paylines.
Once a cluster forms, it’s cleared from the grid, and new symbols drop in. Each cascade gives another chance to win from the same spin. This brings the first bonus feature into play.
The Bonus Feature Stage
During this stage, winning symbols normally disappear and give you a cascade/tumble with new symbols filling the newly vacated spaces. If you get another win, the process repeats until no more new wins are formed.
Some games reward large clusters or consecutive cascades by triggering bonus features such as free spins, multipliers, or power-ups. The longer your chain reactions, the higher your potential return.
The Power of Cascades
Since cascades were first found in 2011, and they are used in most Megaways slots, all grid slot games deploy this feature. This allows you to win repeatedly from each spin. Big or specific cluster combinations can lead to bonus features and other extras.
Quick Fact: The tumbling reels feature was first introduced in NetEnt’s Gonzo’s Quest slot in 2011.
Grid Slots Bonus Features
Bonus features in grid slots online build on their cascading mechanics to keep gameplay active and unpredictable. Many grid slots also feature thrilling bonus rounds and multiplier wilds, which boost excitement and can significantly increase payouts.
The overall design focuses on momentum—rewarding players for extended win sequences rather than single-line hits. Many titles include the following bonus features.
Cascading Wins, Tumbles, or Avalanches
When a winning cluster is created, the winning symbols disappear and are replaced by new symbols. This allows for consecutive wins if you manage to get successive winning clusters. This can lead to big wins or trigger additional bonus features, such as increasing multipliers.
Bonus Meter/Collection System
A winning cluster can contribute to a meter bringing in various types of wild symbols, cash prizes, or bonus features. (Quickspin’s Golden Glyph can lead to Power Wild symbols, bringing in Power-Up features that give you more wilds and remove certain types of symbols).
Free Spins
This bonus feature is often triggered either by scatter symbols or by reaching a certain number of cascades in one spin, and these usually combine all the base game mechanics in a more volatile setup.

Grid Slot Providers
Play’n GO is probably the provider most famous for the best grid slots, but many top studios have developed their own take on the grid slot format. Some of the most active include:
Scatter Pays Slots
Scatter Pays slots use a payout system that ignores paylines and adjacency altogether. Wins are created when a number of matching symbols appear anywhere on the grid or reels, regardless of position.
For example, landing eight or more identical symbols anywhere on the screen might trigger a payout. This system gives every spin a wider hit potential, since symbols don’t need to connect.
➡️ How it Works: The designated Scatter symbol is the one symbol in the game that does not need to conform to paylines or adjacency rules. It pays out based on how many instances of that symbol appear anywhere on the screen
➡️ Bonus Trigger: While Scatters can award a cash prize for hitting a certain number, their most common function is to trigger the slot’s main bonus feature, such as a Free Spins round or a Bonus Game, usually by landing 3 or more symbols simultaneously.
➡️The “All-Ways” Win: Sometimes, online slot games will have a mechanic where all their symbols are essentially Scatters for payout purposes. This means a win is granted for a minimum number of matching symbols anywhere on the screen, not just the bonus symbol
Scatter Pays vs. Cluster Pays
While both use large grids, Scatter Pays slots differ from Cluster Pays slots in one key way: Scatter symbols don’t need to touch to win. Matching symbols can appear anywhere on the grid.
For example, Sweet Bonanza by Pragmatic Play uses the Scatter Pays mechanic. It rewards players for the total number of matching symbols, regardless of where they land.
Here’s a closer look at the differences between the two:
| Cluster Pays | Scatter Pays | |
| Function | Defines a winning combination for standard symbols | Defines how a special symbol pays or triggers a bonus |
| Positon | Symbols MUST touch each other (adjacent) | Symbols CAN appear anywhere on the screen (non-adjacent) |
| Typical Reward | A cash payout based on the size of the cluster | A trigger for a major feature, usually Free Spins or a bonus game |
Best Grid Slots
With most slot developers creating Cluster Pays slots, more and more games are available. Experts often rank the best grid slots based on their dynamic gameplay and winning potential.
In fact, these games are consistently rated highly for their engaging gameplay and strong winning potential.
Our expert team has compiled a meticulous list of the best grid slots to date that are also some of the best online slots in the UK:
| Rank | Slot | Provider | RTP | Max Win | Volatility |
| #1 | Jammin’ Jars 2™ | Push Gaming | 96.4% | 50,000x | High |
| #2 | The Border | Nolimit City | 96.17% | 44,288x | Extreme |
| #3 | Uncle Profit | Print Studios | 96.08% | 50,000x | High |
| #4 | Cluster Tumble | Relax Gaming | 96.4% | 20,000x | High |
| #5 | Reactoonz 2 | Play’n GO | 96.2% | 5,083x | Med–High |
| #6 | Golden Glyph 2 | Quickspin | 96.09% | 26,800x | High |

| #9 | Pirots | ELK Studios | 94% | 10,000x | Med–High |
| #10 | Fear the Dark | Hacksaw Gaming | 96.25% | 5,000x | Medium |
#1 Jammin’ Jars 2™
There is no doubt in our minds that Jammin’ Jars 2 by Push Gaming should take the number one spot on our list of the best grid slots. The original Jammin’ Jars was very close to the top spot, but with more than double the max win—a whopping 50,000x—the sequel stole the show. The grid here is huge—8×8—and it comes with Cluster Pays mechanics, increasing multipliers, seven bonus features, and an above-average RTP. And if that wasn’t enough for you, add to it the awesome setup of fruity symbols and bouncy disco music cheering you on!
#2 The Border
No list would be complete without a Nolimit City grid slot. We loved playing The Border, where the innovative provider introduces their xCluster™ mechanic. The feature increases the win multiplier by 1 for each unique symbol cluster. It is no surprise that their first-ever grid slot went out with a bang. The 44,288x max win, the extreme volatility, and an RTP of 96.17% make a very attractive combination. True to form, Nolimit offers 10 bonus features, amazing audio and visuals, and an expanding grid.
#3 Uncle Profit
Print Studios is known for its striking visuals, and Uncle Profit is no exception. The slot introduces us to a lovely neighbourhood with cute gnomes and transitions into a party scene where the gnomes turn mischievous. Add to that a potential 50,000x max win, high volatility, combined with the 25.29% hit frequency, and it truly is a party!
#4 Cluster Tumble
Unlimited free spins and multipliers? That’s right, Cluster Tumble from Relax Gaming gives you that on top of the 20,000x max win and a 96.4% RTP. But that’s not all; the great design set in the Himalayas is enjoyed on an 8×8 grid. What’s more, you get to go on an adventure and search for the missing lead character, cheered on by an adventure-style soundtrack. During the Free Spins feature, you get a real shot at winning big, due to the multiplier rising in multiples of 3.
#5 Reactoonz 2
The energetic aliens are back in Reactoonz 2 by Play’n GO. The characters are colourful and super cute, and are accompanied by a great soundtrack. The slot gives exciting action in bonus features with Gargantoon wilds, which can grow up to 3×3 in size. It may not be a grid slot for absolute beginners, but if you’re looking for fast-paced and exciting gameplay, Reactoonz 2 is your slot. Additionally, the 5,083x top win potential and the 96.2% RTP with medium to high volatility are not too shabby either.
#6 Golden Glyph 2
This ancient Egyptian-themed sequel from Quickspin packs 10 different bonus features. The Golden Glyph 2 slot stuns with sharp graphics and a serene desert background. Moreover, the provider offers a max win of 26,800x, double the prequel. Just like in the original, tumbling reels and Power-Ups are the main stars of the gameplay. Add to that unlimited free spins and multipliers up to 50x, and you have a top-notch grid slot.
#7 Hand of Anubis
Slot lovers know that Hacksaw Gaming packs a punch when it comes to dark themes and graphics. Hand of Anubis is no exception; it wows with the afterlife Egyptian theme combined with the horror factor. In addition to the visuals, the gameplay doesn’t disappoint either. The unlimited free spins are always welcome, as well as multipliers that go up to 9,999x. The RTP is above average at 96.24% and the max win is 10,000x your bet.
#8 Mine Defender
Mine Defender by ELK Studios is a gem for sci-fi online grid slots fans. It is visually striking, staged in a deep mine with colourful robots and gems. Additionally, if you love Scatter Pays, you’re in for a treat. Although the RTP is 94%, the medium volatility offers that solid balance and a shot at the 10,000x max win.
#9 Pirots
If you have been around long enough, you must be familiar with Pirots from ELK Studios. Although several sequels followed it up, we honour the original here. The provider introduces a CollectR™ mechanic—a variation of Cluster Pays, where birds collect symbols and gems of the same colour to create winning combinations. The visuals are super colourful and inviting, and the soundtrack encourages the gameplay. The max win here is 10,000x the bet, and the RTP is 94%.
#10 Fear the Dark
Last but not least, we add another Hacksaw Gaming gem, Fear the Dark. Although the title is spooky, the monsters and ghosts here are colourful and goofy. The scene is set at a graveyard and is quite a fun slot to play. As usual, the audio-visual side is superb, and the bonus features bring a lot to the table. RTP of 96.25%, max win of 5,000x, unlimited free spins, and medium volatility are a pretty good combination overall.
Origins of Grid Slots
Grid slots evolved naturally from the progression of video slots and mobile puzzle games:
- Video Slots to Online Play: Once digital ones replaced physical reels, developers could experiment with layouts and mechanics beyond traditional paylines
- Puzzle Game Influence: The drop-and-clear mechanics of games like Tetris and match-three puzzles inspired the cascading feature now central to grid slots
While it’s difficult to pinpoint the single “first” grid slot, a number of developers and games were instrumental in establishing the format:
- Pioneering Developers: Companies like Play’n GO and NetEnt are often credited with popularising the format. Play’n GO, in particular, has a vast portfolio of successful grid slots online
- Early Games: Games that utilised cascading wins and Cluster Pays on larger-than-average reel sets were the precursors. When a game combines a large grid with the cascading mechanic, it falls into the category of a modern grid slot
Note: The grid slot is a fusion of the traditional slot machine’s betting structure with the tile-clearing mechanics of modern puzzle games. It maximises screen space for symbols and potential consecutive wins.
Pros and Cons of Grid Slots
Grid slots bring freshness and excitement, especially for players who are tired of the same 5×3, fixed payline format. However, for some, they might be overly complex or have a low win frequency.
Take a look at our list of pros and cons to help you decide if grid slots are the right choice for you:
- Aren’t bound by fixed paylines and offer a puzzle-style gameplay
- Cascading mechanics give potential for more wins from the same spin
- No rigid “left to right” payline constraints on fixed lines
- High volatility means the wins may be big when they hit
- Bonus rounds, multipliers, wild modifiers, or power-ups tied to cascades
- Require players to endure dry spells
- The cluster and cascade logic might seem confusing
- With clusters of 5+ and adjacency needed, small partial matches don’t count
- High variance doesn’t automatically mean better odds
- Some games might overload with extras so that the base game feels cluttered
