Cluster pays slot games award wins when matching symbols land connected to each other on the grid instead of along paylines. This page collects titles whose makers document that mechanic and publish the supporting figures, 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 the cluster mechanic. Volatility labels and maximum wins appear only where the studio publishes them, 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.
Last checked: August 1, 2026.
Mechanics and figures below come from official provider pages and releases. Where a studio does not publish a figure on its current public page, the cell says so instead of borrowing a third-party estimate. Provider risk scales are not equivalent between studios, and two official sources can even disagree with each other — one such case is flagged in the table.
What Counts as a Cluster Pays Slot
A cluster pays game requires a provider-defined number of matching symbols to touch — usually horizontally or vertically adjacent. Many modern examples start the count at five symbols, but the minimum is set by each game and must be read in its rules, not assumed. Most of these games also clear winning symbols and drop new ones into the gaps, so one paid spin can resolve through several waves. The terminology — minimum cluster sizes, cascades, and how providers describe them — is covered in the mechanics explainer; this page is the game list.
Cluster Pays Slots: Verified List
| Game | Cluster rule (as published) | Volatility (as published) | Published RTP | Max win (as published) |
|---|---|---|---|---|
| Aloha! Cluster Pays (NetEnt) | Clusters on a 6×5 grid; Sticky Win Re-spins and Substitution Symbols | Current NetEnt product page: field blank; Evolution demo listing: Low | 96.42% | Current NetEnt page: 700x; Evolution demo listing: up to 10,000x |
| Le Bandit (Hacksaw Gaming) | Wintype: Cluster Pays — 5+ matching symbols connected on a 6×5 grid; Super Cascades | 3/5 | 96.34%, 94.23%, 92.17%, 88.36% | 10,000x |
| Jammin’ Jars (Push Gaming) | 5+ matching symbols on an 8×8 cascading grid; Wild Jam Jars carry multipliers applied to wins they contribute to | High | 96.83%, 94.25% | Max win not published; highest observed win displayed by Push Gaming: 19,998.5x |
| Reactoonz (Play’n GO) | 5+ adjacent symbols on a 7×7 grid; cascades charge the Quantum features and Gargantoon | Not published* | Not published* | Not published* |
| Sugar Rush (Pragmatic Play) | Clusters of 5–15+ on a 7×7 grid; tumble mechanic | Not shown* | 96.50% | Not shown* |
| Fruit Party (Pragmatic Play) | 7×7 cluster-pays grid with tumbles and random multipliers | High, per Pragmatic Play’s official release | 96.50% | Not shown* |
| Cosmic Clusters (Pragmatic Play) | Clusters of 5–14 symbols; tumbling reels | Not shown* | 96.45% | Not shown* |
| Hot Pepper (Pragmatic Play) | 5+ adjacent symbols on a 7×7 grid; tumbles | Not shown* | 96.45% | 10,000x |
* Not shown / not published on the studio’s current public game page — the cell reports that fact instead of borrowing an estimate. The official NetEnt and Evolution listings for Aloha! Cluster Pays also disagree on maximum payout, so the current in-game rules should take precedence. The current NetEnt page additionally discloses a 21% hit frequency; hit frequency counts qualifying wins and does not predict session length or profitability.
Best for: quick category picks
| If you want | Data-anchored pick |
|---|---|
| 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 |
| NetEnt’s first Cluster Pays release | Aloha! Cluster Pays — released in March 2016 |
| A provider-disclosed hit frequency | Aloha! Cluster Pays — 21% on the current NetEnt page |
These are data-based category picks, not a ranking from best to worst — provider scales and disclosure practices differ too much for one.
Candidates Awaiting Provider Data
Le Cowboy’s official page confirms winning clusters and Super Cascades, but does not currently expose the full game-data block. Le Fisherman’s public page describes Golden Squares and its bonus systems but does not provide enough information to verify the underlying win type. Both remain outside the main table until fuller official data is available, rather than entering on aggregator numbers.
Popular Games That Are Not Cluster Pays
Several of the most-searched grid slots use a pays-anywhere, count-based system — often marketed as “scatter pays.” Their official descriptions award wins for matching symbols anywhere on the screen, with no adjacency requirement. That difference is not cosmetic: adjacency changes which board states can pay and how cascades resolve. Sweet Bonanza and Gates of Olympus are the usual examples asked about, and both belong to the pays-anywhere group; see the Sweet Bonanza alternatives page and the Gates of Olympus alternatives page for that family. For a side-by-side view of payout systems, see the payout-systems table in the special symbols guide.
Risk Levels Across These Games
The mechanic itself does not imply a risk band. Within this list alone, published labels run from Hacksaw’s middle 3/5 on Le Bandit to an explicit High on Jammin’ Jars and Fruit Party, one official ecosystem shows two different signals for the same game, and several studios publish no label at all. Treat the mechanic and the risk rating as two separate columns to check — the rating methodology and its limits are covered in the volatility guide, and the provider-labelled shortlist by risk band is in the best medium volatility slots list, where Le Bandit also appears.
Filter the database by mechanic and published return, then let the picker choose from your shortlist.

The Bottom Line
Adjacency is the test, and the provider sheet is the source. Pick from the documented list, read the risk label only where the studio publishes one, and verify the deployed RTP version in your own lobby before comparing.
