Cascading slot games resolve wins in waves: winning symbols are removed, new ones drop into the gaps, and a single paid spin can settle through several evaluations. This page collects titles whose makers document that mechanic under their own names — Avalanche, Tumble, Super Cascades — and it keeps the same admission rule as the rest of this site: provider materials only, no aggregator estimates.
Selection rule: a game enters this list only when the provider documents its cascade mechanic. Volatility labels appear only where the studio publishes one, every RTP figure displayed in the cited provider materials is shown, and the deployed version at a specific casino must still be checked before playing.

Mechanics and figures below come from official provider pages and releases. Where a figure is not shown in the pages cited for this list, the cell says so instead of borrowing a third-party estimate. Official sources can disagree with each other — one such case is flagged under the table.
What Counts as a Cascading Slot
The defining rule is re-resolution: after a win, the winning symbols leave the grid and new symbols take their places, giving the same wager another chance to form combinations. Providers attach different extras to that loop — rising multipliers, feature meters, cluster requirements — but the loop itself is what this page indexes. How each game charges features from its waves is a per-game rule to read, not a property of the mechanic.
One Mechanic, Many Names
Providers use different labels in individual games, not one name for a whole catalogue: NetEnt uses Avalanche, Pragmatic Play frequently uses Tumble, Le Bandit calls its loop Super Cascades, Jammin’ Jars is described as an 8×8 cascading slot, Bonanza documents Dual Reactions™ with symbols falling from the top and the right, and Play’n GO’s Reactoonz page describes winning aliens being removed and replaced without a separate branded name. The details behind each label — whether multipliers grow per wave, whether waves are capped, what the loop feeds — vary by game, so the shared pattern never substitutes for the specific paytable.
Cascading Slots: Verified List
| Game | Cascade term (as published) | Win formation | Volatility (as published) | Published RTP |
|---|---|---|---|---|

| Le Bandit (Hacksaw Gaming) | Super Cascades | Clusters — 5+ connected on a 6×5 grid | 3/5 | 96.34%, 94.23%, 92.17%, 88.36% |

| Fruit Party (Pragmatic Play) | Tumbles with random multipliers | Clusters on a 7×7 grid | High, per Pragmatic Play’s official release | 96.50% |
| Sweet Bonanza (Pragmatic Play) | Tumbling feature — winning symbols vanish and are replaced by new symbols dropping from above | Pays anywhere — 8–12+ matching symbols on a 6×5 grid | High, per Pragmatic Play’s official launch release | 96.48% |
| Gates of Olympus (Pragmatic Play) | Tumbling wins — winning symbols disappear and new symbols fall into their positions | Pays anywhere — 8–30 matching symbols on a 6×5 grid | Highly volatile, per Pragmatic Play’s official article | 96.50% |
* Not shown / not published in the provider pages cited for this list — the cell reports that fact instead of borrowing an estimate. The official NetEnt and Evolution listings for Gonzo’s Quest disagree on maximum win — 2,200x on the current NetEnt page versus up to 2,500x on the Evolution listing — and also describe its volatility differently, so neither label should be normalized into a single value: the rules of the launched version take precedence.
Best for: quick category picks
| If you want | Data-anchored pick |
|---|---|
| A classic payline-based Avalanche example | Gonzo’s Quest — paylines with a base-game multiplier rising to 5x |
| The loop on variable ways | Twin Spin Megaways — Avalanche with up to 117,649 Megaways |
| The highest RTP displayed on a provider page in this list | Jammin’ Jars — 96.83% |
| The widest published configuration spread | Le Bandit — 96.34% to 88.36% across four versions |
| Cascades that charge a feature meter | Reactoonz — waves feed the Quantum features and Gargantoon |
These are data-based category picks, not a ranking from best to worst — provider scales and disclosure practices differ too much for one.
Two Axes: The Loop and the Win Type
A cascade decides how a win resolves; the win type decides how a win forms — and a cascade loop can be combined with several different win systems. The table above shows four of them. Gonzo’s Quest pairs its Avalanche with classic paylines. Twin Spin Megaways and Bonanza run the loop on variable adjacent-reel ways. The cluster block pairs waves with adjacency wins — the cluster side of those games is covered in the cluster pays list. Sweet Bonanza and Gates of Olympus pair tumbles with pays-anywhere counting — their families live on the Sweet Bonanza alternatives page and the Gates of Olympus alternatives page. Searching by the loop alone therefore mixes four different ways of paying; check both axes before comparing games.
Do Cascades Add Extra RTP?
No. Cascades are part of the game’s approved mathematical model, and the published RTP already includes all wins generated during the sequence. The mechanic does affect the distribution and timing of outcomes — wave chains, rising multipliers and feature charging shape how sessions feel — but a second or third wave is not an extra return added on top of the stated percentage. Compare the published RTP and volatility separately from how the game presents consecutive evaluations, the same way the RTP guide separates long-run cost from session shape.
Filter the database by mechanic and published return, then let the picker choose from your shortlist.

The Bottom Line
The loop is not the win type — and it does not add extra RTP. Pick from documented implementations, check which axis forms the win, and verify the deployed RTP version in your own lobby before comparing.
