Gonzo's Quest

Among slots, Gonzo’s Quest: The Search for El Dorado is legendary. Gonzo's Quest has been a mainstay among the most popular slots in the US since its release in 2010 and is widely known for its tumbling reels or avalanche feature.

The storyline of this slot revolves around Gonzalo Pizarro who treks through the Amazon Jungle to find El Dorado, the lost city of gold.

When you form a winning combination on the tumbling reel, the winning symbols disappear and replaced by new symbols. The consecutive clearing of symbols rewards you with progressive multipliers of x1, x2, x3, and x5.

Matching three or more bonus symbols triggers the Free Fall bonus feature rewarding you with ten or more bonus games/free spins. In addition, the value of each multiplier gets tripled during this round.

With 95.97% RTP, and medium-high volatility, this slot is one of the most influential NetEnt slots.

Raging Rhino

Raging Rhino

Released to online casinos in 2015, Raging Rhino from WMS quickly became one of the most popular slot machines. However, it’s the 2019 cascading reels feature release that positioned Raging Rhino Megaways among the top slots here.

This high volatility casino game still hinges on the wild multiplier Serengeti, the Diamond bonus round symbol, and, the famous slots symbol of the Raging Rhino itself.

The winning combinations in this slot can be found across as many as 117,649 paylines, and further matching symbols make way for new symbols, which further triggers free spins and bonus rounds.

Jammin’ Jars

Jammin' Jars

Jammin’ Jars is an eight-by-eight grid slots game from Push Gaming. The wins come in the form of clusters of symbols, moving away from the standard format of paylines that most slots rely on.

After each win, the fruits symbols fall to make space for more symbols. The wild Jammin’ Jar is the main symbol that builds up a multiplier whenever a winning combination is formed. It remains on the grid for the re-spins while shifting from down to up or left to right.

Reactoonz 2


This slot is another creation of Play’n Go and a sequel of Reactooz, which is quite popular among the slots players. You can win max up to 5083x time of your bet in this slot game.

Reactoonz 2 is played on a seven-by-seven format. When five or more matching symbols land next to each other in a cluster forming winning combinations, they burst for more symbols to fall on the cascading reels.

The one-eyed and two-eyed icons work as low and high paying symbols. There can be up to fifteen symbols involved in a win. When one-eyed symbols fluctuate their eyes and become a part of winning combination, they create an electric wild randomly on any spot of the exploding symbols.

The two bonus meters are the exciting features of Reactoonz 2. The Fluctometer activates when an electric wild lands on the reels. When charged, the Fluctometer will throw out 1-3 electric wilds to create a cascade.

When two or more electric wilds appear on the reels and trigger the Wild Pair Explosion, but don't pay out rewards, the Quantometer gets charged and brings in supersized Energoons and Gargatoons as extra wilds in the game.

Who Wants to Be a Millionaire

Who wants to be a millionaire?

You don’t need to be a whizz at general knowledge to play the Who Wants to Be a Millionaire slot game – you only need to know how to play slots.

During the free spins feature, the Rich Uncle Pennybags keep moving on the board, while adding multipliers and new properties on the way.

Temple Tumble Megaways

Temple Tumble Megaways

If you want to play a cascading slot with a Chinese theme, Temple Tumble Megaways is a perfect option. It’s not as laden with lucky gold symbols as many slots are, instead the reels are being flanked by a Guardian Lion and Tengshe Dragon.

The golden Buddha symbol is the most valuable symbol, while the explorer who is searching the treasure in the jungle acts as the wild symbol.

The wild symbols exist on reels two to six and substitute for all other symbols. Matching symbols on three or more adjacent reels will constitute a win.

Temple Tumble Megaways is one of the best tumbling reels slot games to play in the grid format. The stone blocks that lie next to winning symbols will explode and new symbols will fall down to fill the space and create more chances to win.

This slot comes with various bonus features, such as free spins, multipliers, and re-spins. Clearing all stone blocks will trigger six free spins.

This is a highly volatile slot with 96.25% RTP and provides 46,656 ways to win.

Moon Princess

Moon Princess

Moon Princess is another Play’n Go title to make it in our list as one of the top slot in a stack of Megaways-boosted Big Time Gaming slots with cascading reels. It is evidently based on Sailor Moon⁠, the anime series and set in a five-by-five grid.

Matching three or more symbols in the grid either horizontally or vertically charges the Princess Trinity Meter, which further activates free spins, re-spins and multipliers. You may also get a chance to choose the number of free spins and grow the multiplier to a maximum of x20.

Moon Princess

Like other slots of this build, the cascading reels come into play when cluster wins pop on a single spin, with each matching combination making way for more prizes until the spins expire and symbols stop making wins.

The trio of Love, Star and Storm use their magical abilities to help you win an outstanding prize when all the 25 symbols are cleared from the grid during the free spins feature.

Are Cascading Slot Games Good for Beginners?

Yes. These slots have a cluster payout feature, which is quite simple to fathom. If you have ever played Candy Crush, you will relate with the concept of cascading reels even better. Matching three or more symbols that are lying adjacent to each other or from top to bottom on a grid will lead to a win, which can further trigger bonus features to multiply the winnings.

It is always advisable to try the demo version of cascading reels slots to understand the gameplay and payouts before you start playing for real money.

How do Tumbling Reels Work

In tumbling reel slots, if a spin yields a winning combination, the symbols burst to potentially make way for more symbols to fall in place and create more combinations triggering spins, free spins and activating multipliers. In other words, these slot games give you an extra chance to win through the tumbling reels feature.

When you play tumbling reels slots or cascading reels slot games, you will notice that these are very similar to standard video slots in terms of operating through a spin button and giving you an option to place your bet, but the difference lies in the dynamic gameplay along with successive and substantial wins through multipliers that you can achieve quite often only on these slots.
