Thunder Coins series
Thunder Coins grew by changing the bonus screen
Playson's Thunder Coins line began in 2024 by fitting a hold-and-win bonus, multipliers and respins onto a compact 3x3 screen. Thunder Coins fixed the franchise's fruit-and-thunder identity in place with five paylines, medium-high volatility and a 5,150x maximum win.

 Thunder Coins XXL: MulticoinPlayson | — | — | 60 |
Thunder Coins XXL expanded the format to 3x5 and 15 paylines in 2025, then added free spins and fixed jackpots. The change was not a straight ceiling increase: its listed maximum falls to 1,000x. XXL instead creates more screen space and more bonus routes while retaining the hold-and-win core.
Thunder Coins XXL: Multicoin shifts to a 5x3 layout but keeps 15 paylines and the 1,000x ceiling. Cash collection, random multipliers, stacked symbols, additive symbols and sticky positions make it the busiest version, with the bonus depending on how coin values and modifiers combine rather than on screen expansion alone.
The progression runs from compression to elaboration. Thunder Coins carries the largest listed ceiling on the smallest grid; XXL adds free spins and fixed jackpots; Multicoin turns the same jackpot framework into a collector system with more interacting symbol states.
