Playson Debuts BoosterCells Mechanic in Thunder Coins XXL Slot Series

Playson unveiled Thunder Coins XXL: BoosterCells on 17 September 2026, equipping its established slot series with a novel BoosterCells Feature. This mechanic introduces new ways for operators to engage players through coin value merging, random boosts, and accelerated bonus rounds—all underpinned by explicit in-game triggers and buy-in functions.

BoosterCells Mechanic: How It Works

Thunder Coins XXL: BoosterCells stands out by enabling stored Coin values on every reel. The BoosterCells Feature activates via the Bonus Game, which begins when Coin symbols land on both reels 1 and 3 and a Thunder Coin appears on reel 2. When a Coin lands on a position already holding a collected value, the two amounts are instantly merged, raising the potential payout. Further, Thunder Coins can randomly boost the value of multiple stored Coins during the round, increasing win potential across subsequent spins.

Thunder Feature and In-Game Jackpots

The Thunder Feature triggers when any Coin symbol lands simultaneously with a Thunder Coin. When this occurs in the Main Game, the system collects every Coin value on the reels, including potentially one of four in-game Jackpot prizes, and aggregates them into the spin’s total win. If triggered within the Bonus Game, all collected values plus any Jackpot win are credited to the Total Win for the round. This structure supports casinos seeking titles with layered volatility and evolving jackpot engagement.

Bonus Entry and Buy-In Options

Bonus round entry can be accelerated by the Pile of Gold Feature, which Playson describes as a random trigger. When any Coin symbol lands, the feature may activate, adding sufficient Coin and Thunder Coin symbols to meet the Bonus Game activation criteria within the same spin. Players—or automated test agents—are offered two Buy Bonus Game choices. The "Super Buy Bonus Game" guarantees three active Thunder Coins on entry, offering a predictable bonus experience for those seeking direct feature access. Additional Extra Bet options are available, including the Thunder Spin, designed to triple the chance of accessing the Bonus Game in a single spin by ensuring one Thunder Coin appears each turn.

Industry Perspective: Playson’s Product Strategy

Anton Ivannikov, Chief Product Officer at Playson, cited the new mechanic as a pivotal addition to the Thunder Coins XXL family. According to Ivannikov:

“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.”

This release broadens Playson's line-up intended for regulated markets prioritising bonus-rich, feature-led content.

Relevance for Operators and Markets

Operators targeting players who engage with bonus rounds and dynamic features may find Thunder Coins XXL: BoosterCells suitable for acquisition campaigns and retention tools. The stacking and boosting of Coin values, multiple bonus entry points, and several buy-in mechanics offer avenues for engagement across different player segments. With the game launching on 17 September 2026, it represents a real-time case for B2B discussions on game mechanic innovation and diversified player incentives.
