Definition: What Is the Cascading Feature?

The cascading reels feature (also known as Avalanche, Rolling Reels, or Sliding Reels) is a slot mechanic where winning symbols disappear after a successful spin and are replaced by new symbols. This often results in multiple wins from a single bet.

This effect is similar to the mechanics in Tetris or Candy Crush, where rows or groups are removed, and new elements fall into place.

How Cascades Work in Online Slots?

To understand how slots with the cascading feature impact gameplay, here’s an overview of the process:

  1. Spin Starts

    Bet is placed, spin begins.

  2. Win Occurs

    A regular winning combination appears.

  3. Symbols Disappear

    All symbols involved in the winning combination are removed.

  4. New Symbols Drop In

    Gaps are filled with existing or new symbols from above.

  5. New Wins Possible

    New winning combinations may form, continuing the cascade.

  6. Repeats as Long as Wins Occur

    The process continues as long as new combinations appear.

Important: Each cascade is played with the same bet value, meaning no additional costs apply. This means a single spin can result in multiple payouts.

Pros and Cons of Cascades in Slot Games

  • Exciting Gameplay: Extended spins create action and surprises.
  • Increased Winning Chances: Multiple wins from a single spin are possible.
  • Combination with Multipliers & Free Spins: Many slots increase the multiplier with each cascade.
  • Risk-Free Extra Wins: No additional bet is required once a cascade starts.
  • Not Always Profitable: A cascade doesn’t guarantee high payouts.
  • High Volatility Possible: Slots with cascades can have long dry spells.
  • Increased Excitement Can Lead to Longer Play Sessions: The cascade mechanic encourages continued play.

Different Types of Slots With Cascading Feature

The cascade feature has different variations depending on the game developer and slot mechanics. Here are the most important types of cascades in online slots and their unique characteristics:

Classic Cascades (Cascading Reels) – Seen in Gonzo's Quest

The classic cascade mechanic follows a simple principle: When a winning combination appears, the involved symbols disappear, and new symbols drop in from above. This can create new winning combinations, extending the spin and increasing the winning potential.

Besides Gonzo's Quest, other slots like Extra Chilli Megaways by Big Time Gaming or Temple Tumble Megaways by Relax Gaming use this feature.

Cascades with Multipliers – Seen at Sweet Bonanza

One of the most popular extensions of classic cascades is the combination of multipliers. Each time a new cascade is triggered, a multiplier increases, increasing the win for that round. In some slots, the multiplier starts again at x1 after each new spin, while in other games, it stays the same throughout the bonus round or even increases further.

Well-known slots with multiplier cascades:

  • Sweet Bonanza (Pragmatic Play) – Multipliers appear randomly during the cascades
  • Gonzo's Quest (NetEnt) – Multiplier up to x5 in the base game, up to x15 in bonus rounds
  • Aztec Gold Megaways (iSoftBet) – Every win increases the multiplier

Cascades with Free Spins Activation – Seen on Extra Chilli Megaways

In this variant, a certain number of consecutive cascades trigger free spins. This means that scatter symbols are not necessarily required – it is enough to get several wins in a row.

Example of the sequence of these cascades:

  • 4 consecutive cascades = 10 free spins
  • 6 cascades in a row = 15 free spins
  • During free spins, additional features such as multipliers or wilds often apply

Cascades with Cluster Pays – Seen in Jammin' Jars

Some slots use Cluster Pays instead of traditional paylines. This means that wins are not formed by fixed lines but by groups (clusters) of identical symbols that touch each other. When a cascade win is triggered, all symbols in the cluster disappear, and new symbols fall into place.

The entire Reactoonz series also uses this feature, which is probably one reason these slots are so popular.

Megaways Cascades – Seen in Bonanza Megaways

The technology in Megaways slots adds extra dynamics to the cascade feature. With each spin, the number of symbols on each reel varies, changing the number of possible winning ways. Due to the varying reel heights, cascades can create particularly large win chains.

Exploding Cascades – Seen in Gates of Olympus

This variant is similar to classic cascades but takes it further: instead of just replacing symbol rows, entire groups of symbols “explode,” making room for completely new symbols. This is why this feature is separately marketed as the Tumble feature.

Gates of Olympus
Rating: 99 / 100

When a winning combination occurs in the Gates of Olympus, the symbols explode, and new ones fall into place. This feature is primarily about visual effects and excitement.

Which is the most popular cascade variant?

Each variant has its own advantages and suits different types of players:

  • Maximize winning streaks? Classic cascades (Gonzo’s Quest).
  • Extreme volatility & big multipliers? Megaways cascades (Bonanza Megaways).
  • Free spins triggered by cascades? Ghost Slider or Extra Chilli Megaways.
  • Cluster wins instead of paylines? Reactoonz or Jammin’ Jars.

Cascade slots are one of the most exciting features in modern slot games. The variety of versions ensures that the gameplay never gets boring.

Strategic Considerations When Playing Cascade Slots

Since the cascade feature offers higher winning potential, many players develop strategies to make the most of this mechanic.

  • Prioritize cascade slots with multipliers: Some slots increase the multiplier with each cascade, such as “Gonzo’s Quest” by NetEnt.
  • Use demo mode: Learn how the cascade feature works in a slot without risk by playing the free demo before wagering real money.
  • Consider volatility: Cascade slots often have higher volatility – meaning big wins are rarer but can be highly rewarding.
  • Be open to experiments: Even discussed strategies like the 2 euro slot machine trick can be tried. But be careful: don’t lose track of your budget!

Game Developers of Cascading Slot Games

Cascade slots extend gameplay, and some game providers specialize in them. Three stand out: NetEnt, Pragmatic Play, and Big Time Gaming (BTG). These companies have popularized and enhanced the cascade feature with multipliers, Megaways, or free spins.

Netent: Pioneer of Cascading Slots

NetEnt was one of the first developers to implement cascades in a popular slot. The legendary Gonzo's Quest introduced the Avalanche feature – one of the first cascading mechanics in modern online slots.

NetEnt often uses multipliers that increase with each cascade, significantly increasing the winning potential with consecutive hits. The slots are characterized by high production quality, smooth animations, and innovative features that take the gaming experience to a new level.

Pragmatic Play: Master of Explosive Cascades

Pragmatic Play has incorporated Exploding Cascades (Tumble) into many of their most successful slots. These games often combine cascades with high multipliers or cluster pay mechanics to provide huge winning opportunities.

Pragmatic's cascading slots often have high volatility, meaning big wins are possible but don't happen on every spin.

Big Time Gaming: The Megaways Revolution

Big Time Gaming has created one of the biggest innovations in the slot space with Megaways. Many of their Megaways slots combine dynamic reel heights with cascades, resulting in thousands of ways to win.

BTG has created the most dynamic cascading experience – with constantly changing reels and millions of possible combinations in a single spin, making for extremely varied and exciting game rounds.

Conclusion: Cascades Enhance the Gaming Experience

Cascading reels are one of the most innovative and exciting mechanics in modern slot machines and can be found in almost every crypto casino. They allow you to achieve multiple consecutive wins with just a single spin – without any additional bet. This dynamic makes the gaming experience much more interactive than classic slot machines, where each spin is independent of the previous one.

However, not all cascades are the same: There are different variants, from classic cascades to Megaways cascades, cluster pay cascades or explosive tumble cascades. While some slots combine the feature with increasing multipliers, others trigger free spins or offer unlimited cascade chains. Which variant is best depends on your own preferences.

Play responsibly. Gambling can be addictive.
