What Is a Grid Slot?

Screenshot of Rich WIlde and the Tome of Insanity by Play'n GO

A grid slot is a type of online casino slot game played on a grid layout, rather than the traditional format of reels and fixed paylines.

Instead of creating lines of matching symbols from left to right, grid slots allow winning combinations to form anywhere on the grid. Wins are typically determined either by clusters of adjacent matching symbols or just landing a minimum number of matching symbols anywhere on the grid.

The introduction of grid slots took slot gaming to a new level with dynamic and engaging gameplay. Play'n GO and NetEnt, with games like Gemix, Aloha! Cluster Pays, and Reactoonz, are often cited as pioneers of this game type.

Unique mechanics and innovative bonus features have made these casino games increasingly popular among gamblers. We'll explore some of the most common features later on this page.

How To Recognise Grid Slot Games

You recognise grid slot games by their key characteristics like a rectangular grid. Here are some key characteristics that can help you identify a grid slot:

New Grid Slots

Graphic for grid slots

New grid slots are full of the latest innovations regarding features, gameplay, game design, and much more. New casino slots are launched weekly, and more and more of them fall under the grid slot category. We picked a few of the latest for you to try!

Here are a few recently released grid slots:

Grid Slot Types

Grid slots are a versatile category of slot games with something beyond traditional paylines. Innovative designs, such as cascading symbols and cluster pays, are often at the core of these games.

This diversity means there's something for everyone, whether you prefer strategic gameplay, immersive themes, or games that keep you engaged with dynamic bonus features.

Below, we'll explore the different types of grid slots and what makes each one special. Check out which suits your style best!

Classic Grid Slots

Wild Frames by Play'n GO

Classic grid slots rely visually on an outlook that reminds the player of the symbols and design of classic casino slots. Where these slots differ is the modern layout of the grid slot playing area.

Grid slots jilt the reels for a rectangular grid and often reward players through a different pay mechanic that can include forming winning combinations just by landing on a set number of matching symbols anywhere on the grid.


Cluster Pay Grid Slots

Reactoonz by Play'n GO

Cluster Pay Grid Slots incorporate a payout mechanic where wins are based not on fixed paylines but on forming clusters of matching symbols. Usually, a minimum of five adjacent symbols is required, but the number varies between games.

Top cluster pays slots combine this with a wide variety of themes, while the dynamic layout allows for a multitude of features to be added. These are ideal for the captivating gaming experiences that players are looking for.


Cascading Grid Slots

Le Bandit by Hacksaw Gaming

Cascading grid slots include a mechanic which removes winning combinations from the grid and replaces them with new symbols. This can lead to multiple consecutive wins with just one spin, as the action is repeated as long as winning combinations are formed.

Games that include this feature are sometimes called tumble slots. For additional excitement and to boost wins, some games include increasing win multipliers as more and more cascades take place.


Features of Grid Slots Online

Grid slots online offer a fresh and dynamic gameplay experience that keeps you engaged. Grid slots tend to veer towards the high end of the volatility scale, offering attractive and potentially substantial payouts but also requiring grinding out extensive dry spells.

Here is a quick overlook of some common features of grid slot games:

Grid Slots vs Multi-Line Slots

Graphic for slot games

Grid slots and multi-line slots differ in the way the games form winning combinations for payouts. The games offer distinct gameplay experiences that appeal to different types of players.

Grid slots break away from traditional paylines, using cluster or scatter pays mechanics. Wins are achieved by either grouping matching symbols adjacent to each other or landing a required number of matching symbols on the grid.

Add in the common cascade feature and you can see dynamic chain reactions, bonus features, and exciting visual effects.

Multi-line slots feature a number of paylines that run across the reels in various patterns. Matching symbols have to land on these predefined paths to secure wins. Typically, winning combinations are formed left to right, starting from the leftmost reel.

While multi-payline slots provide structured gameplay, grid slots offer a more modern, unpredictable experience with the potential for consecutive wins in a single spin.

FAQ

A grid slot is an online slot game that uses a grid layout rather than the traditional 3 or 5-reel setup. Symbols drop onto a grid, and wins are typically paid for landing enough matching symbols anywhere or forming clusters of matching symbols.

Special features, such as multipliers, expanding wilds, or bonus rounds, are common for many grid slots.

The best grid slots are:

  1. Money Train 4 by Relax Gaming
  2. Gates of Olympus 1000 by Pragmatic Play
  3. Le Bandit by Hacksaw Gaming

These titles are highlighted for their use of various features, good win potential, and for providing electric casino entertainment.

Typically, grid slots pay wins based on either a cluster pays mechanic or scatter pays mechanic. The former pays when a cluster of adjacent matching symbols, usually at least five symbols, is formed on the grid; the latter pays when a set number of matching symbols is visible anywhere on the grid.

You can find grid slots at numerous UK online casinos. Many UK-licensed slot sites, like PlayOJO and 21 Casino, have included grid slots in their game libraries. While traditional slots with reels are still more common, grid slots have been growing both in popularity and in numbers.

Yes, some grid slots have jackpots. Relax Gaming has incorporated its Dream Drop jackpot product into some of its grid slots like Banana Town, too.
