Playson has released Thunder Coins XXL: BoosterCells on 17 September 2026, adding a new reel-based mechanic to its established Thunder Coins game family. The release centres on the BoosterCells Feature which allows Coin values collected during the Bonus Game to remain on the reels and increase as additional values land on the same positions.

The new title continues Playson’s approach of developing familiar game concepts through additional features rather than relying solely on a new theme. In this case, the central idea is progression within the Bonus Game, with stored values creating a visible record of previous Coin landings and allowing subsequent symbols to build on them.

The game uses a 3×5 layout with 15 lines according to Playson’s official game information. Its structure combines the new BoosterCells mechanic with returning Thunder Coins features, four in-game jackpot levels and several optional routes intended to increase access to bonus play.

How the BoosterCells Feature works

The Bonus Game begins when Coins land on reels one and three together with a Thunder Coin on reel two. Once activated, the BoosterCells Feature stores collected Coin values directly on the reel positions.

The mechanism is designed around accumulation. When a new Coin lands on a position that already holds a stored value, the two values are combined. This means a previously collected amount can become part of a larger total rather than being treated as an isolated value.

Thunder Coins provide another layer to the feature. Playson states that Thunder Coins land on reel two and remain active throughout the feature. They can collect the Coin values visible across the reels while also having the ability to randomly increase multiple stored values.

From a gameplay perspective, this gives the Bonus Game a clear sense of progression. The value of earlier Coin symbols can remain relevant over subsequent spins within the round, while new landings can potentially add to established positions. The design therefore places greater emphasis on how values develop during the feature rather than only on individual symbol outcomes.

Returning Thunder Feature adds collection potential

The release also brings back the Thunder Feature as a core part of the Thunder Coins formula. It is triggered when a Thunder Coin lands alongside any Coin symbol.

When activated, the Thunder Feature collects the values of Coins in play and adds the resulting amount to the win for that spin in the Main Game. During the Bonus Game, the collected values are added to the Total Win.

The feature also works with the title’s four in-game jackpots. Playson confirms that Mini, Minor, Major and Grand Jackpot Coins can appear on the 3×5 grid with jackpot values reaching up to 1,000x.

The interaction between the Thunder Feature and BoosterCells is particularly important to the overall design. Stored values created through the new mechanic can become part of the collection process when Thunder Coins are activated, connecting the title’s new and established systems within the same bonus structure.

Pile of Gold creates another route to the bonus

Playson has also retained a shortcut mechanism through the Pile of Gold Feature. During the Main Game, the feature can randomly add Coin and Thunder Coin symbols to the reels.

According to the game's description, these additional symbols can appear in sufficient quantity to activate the Bonus Game. This gives the title another potential path into its main feature beyond the standard symbol arrangement required for bonus entry.

The Pile of Gold approach is consistent with the broader structure of the release. Rather than leaving bonus access dependent on one trigger alone, Thunder Coins XXL: BoosterCells incorporates an alternative mechanism that can alter the reel setup and create another opportunity to reach the feature.

Buy options broaden bonus access

Players also have access to two Buy Bonus Game options. The Super Buy Bonus Game is designed to provide a more feature-oriented entry by guaranteeing three active Thunder Coins at the start of the bonus sequence.

The title additionally offers two Extra Bet options. Playson identifies these as Double Chance and Thunder Spin. The former doubles the chance of triggering the Bonus Game while Thunder Spin triples that chance and guarantees one Thunder Coin on each spin.

These options create different entry points into the game's feature system. The Buy Bonus alternatives focus on direct access while the Extra Bet functions are designed around changing the probability or conditions associated with bonus activation.

Such mechanisms are increasingly common in modern online slot design, although availability can vary according to market requirements, operator configuration and applicable rules. Players should therefore review the terms presented by the relevant licensed operator before using optional features.

Playson positions the title as an evolution of its series

Playson has presented Thunder Coins XXL: BoosterCells as an evolution of a recognised game family. Rather than replacing the established Thunder Coins concept, the supplier has built the new release around the idea of making Coin values persist and develop during bonus play.

Anton Ivannikov is identified by Playson as the company’s Chief Product Officer. His role is also listed on the supplier’s current leadership page.

Commenting on the release, Ivannikov said: “Thunder Coins XXL: BoosterCells brings a fresh dimension to one of our most recognisable game families, combining the familiar appeal of Thunder Coins with a new mechanic designed to add greater depth to bonus play.

“BoosterCells creates opportunities for players to build on previously collected values, while coveted Thunder Coins can enhance boosted values to keep every spin feeling dynamic. We are confident this latest evolution will resonate with players and further strengthen the player-favourite series.”

The statement frames the release as a continuation of an established product direction with the BoosterCells mechanic serving as the principal new element. The wording also presents the feature as a way to add additional progression to the bonus phase.

A feature-led approach to slot development

The structure of the new game reflects a broader product strategy centred on layering additional mechanics onto familiar slot formats. In Thunder Coins XXL: BoosterCells, the underlying Coin collection concept remains recognisable while the BoosterCells mechanic gives individual reel positions greater importance during the Bonus Game.

This approach may also make the title comparatively straightforward to understand at a functional level. Players can see stored Coin values on the reels then observe whether subsequent symbols add to those amounts or whether Thunder Coins affect several stored positions.

The four jackpot tiers provide another established element within the design. Their integration with the Thunder Feature gives the game a clear high-value component while preserving the central Coin collection structure.

For operators, releases built around established mechanics can also provide a recognisable format for casino portfolios while introducing enough feature variation to distinguish a new title. Playson’s current portfolio includes a wide range of slot games designed for regulated and mobile-focused markets.

Compliance remains relevant to market availability

Playson states that its games are certified and licensed across a broad range of regulated jurisdictions. Its official website also identifies Playson Limited as licensed and regulated in Great Britain by the Gambling Commission and notes a recognition notice from the Malta Gaming Authority.

This regulatory framework is relevant when considering the availability of Thunder Coins XXL: BoosterCells because online gaming content can be subject to jurisdiction-specific technical and legal requirements. The presence of a product within a supplier portfolio does not by itself mean that it will be available through every operator or in every market.

The final availability of the title may depend on licensing, certification, operator integration and local requirements. Players should rely on information supplied by properly authorised operators and applicable regulatory registers when assessing whether a game is available in their jurisdiction.

Conclusion

Thunder Coins XXL: BoosterCells extends Playson’s Thunder Coins portfolio with a mechanic built around persistence, accumulation and interaction between reel values. The BoosterCells Feature gives Coin values a continuing role throughout the Bonus Game while the returning Thunder Feature allows values to be collected as part of the wider game system.

The addition of four jackpots, the Pile of Gold Feature, Buy Bonus options and Extra Bet choices creates a multi-layered feature structure around the central BoosterCells concept. With its release dated 17 September 2026, the title represents another example of Playson adapting a recognised game formula through a new mechanic while maintaining the core identity of the series.
