What Are Cascading Reel Slots?

Temple Tumble Megaways slot by Relax Gaming

Cascading reel slots are a type of game where winning symbols disappear and allow new symbols to drop into their place. The new symbols cascade down on the grid, potentially creating new winning combinations one after another. Sometimes they can trigger an exciting chain reaction of consecutive wins.

Unlike traditional slots where symbols spin and stop on the grid offering a fixed number of paylines, cascading reel slots often come with multiple paylines and more ways to win, as long as the matching winning symbols meet on the grid. 

The first cascading reel slot was Gonzo's Quest by NetEnt. The game revolutionised the whole industry. Its innovative avalanche mechanic inspired other developers to do the same, and nowadays we get to enjoy hundreds if not thousands of cascading reel slots in many different online casinos. 

How To Recognise Cascading Slots Online

You can recognise cascading slots online by their layout, game descriptions and how the winning combinations are formed during the gameplay.

Types of Cascade Slots

Different types of cascade slots have unique features and mechanics that distinguish them from each other. Thus, they suit diverse gaming preferences. Cascade slots are grid slots, meaning they differ from the traditional ones by their grid layout.

You can see a breakdown of each of them below. 

Classic Avalanche Slots

Classic avalanche slots are typically focused on the simple avalanche mechanic where the reels cascade down to fill the empty gaps on the grid. The idea is to keep players entertained throughout the game while adding more ways to win compared to traditional slots.  

The pioneer of avalanche slots is Gonzo's Quest by NetEnt. After the release and the quick popularity, other developers followed and created similar mechanics in their games. They are called other names depending on the providers, mostly known as cascading slots and tumble slots. They are classic casino games that you can find everywhere.


Jackpot Tumble Slots

Jackpot tumble slots are similar to the classic avalanche slots in terms of the reel mechanism. However, these games come with added jackpot prizes. They can be either fixed, progressive or progressive with multipliers, depending on the game. 

If the slot comes with a progressive jackpot with multipliers, it is called dream drop. For instance Relax Gaming offer several online jackpots with dream drop features. 

The combination of the mechanics and jackpot prizes makes these types of games stand out from the traditional cascading slots. They are ideal for players who enjoy the dynamic gameplay of tumble reels but also the thrill of chasing huge jackpots. 


Megaways Slots With Cascading Reels

Megaways slots with cascading reels take the gameplay to the next level with engaging mechanics. The Megaway feature introduces an exhilarating twist to the games by dynamically changing the number of symbols landing on each reel on every spin. This feature creates tens of thousands of ways to win, offering a unique kind of excitement. 

The combination of Megaways and cascading reels ensures an action-packed and high-volatility gaming experience and a potential for massive payouts. Have a look at the best Megaways slots list ranked by our experts and find your favourites. 

The unpredictability of the reel setup and big potential winnings are appealing particularly to players who thrive on the thrill of risks and rewards. 


Cluster Pay Slots With Tumbling Reels

Cluster pay slots with tumbling reels break away from the traditional paylines, offering innovative gameplay. Wins are awarded when a group of matching symbols connect in clusters instead of lining up in the fixed paylines. Cluster pay slots with tumbling reels deliver fast-paced gameplay with the potential of big, consecutive wins. 

One of the most iconic cluster pay slot is Reactoonz from Play n' Go. 

Tumbling reels provide continuous action and cluster mechanics keep players entertained throughout the game. These kinds of slots are ideal for players who enjoy dynamic visuals, frequent wins and extended play sessions.
