Thunder Coins XXL: Hold and Win: stake and payout guide
A collector animation can combine several values into one payment. Preserve the final settled total rather than adding both the displayed component coins and the already-summed collector amount twice.

What happens in Thunder Coins XXL: Hold and Win
Thunder Coins XXL enlarges the familiar coin presentation and centres its feature on a middle-reel collector. The Thunder symbol gathers eligible bonus values, while the expanded board provides more positions to follow. Its full title matters because Multicoin and BoosterCells are other releases with additional mechanics.
The middle reel has a special role
The developer places Thunder symbols on reel two. In the bonus they remain in place and collect eligible values from the board. Ordinary fruit, bells and sevens explain base-game line results, whereas the coin and collector system explains the Hold & Win feature.
Read the trigger across the three reels
A qualifying entry requires a Bonus symbol on each reel. The tall display does not turn the game into five reels: it is three columns with five rows. This is a common source of confusion when different pages write dimensions in a different order.
Read a result in Australian dollars
The following worked example isolates one operation so the calculation can be followed. The stake and values are constructed inputs, separate from any account promotion or recorded result.
A$2.00 + A$4.00 + A$6.00 = A$12.00 illustrates a collector sum before any other rule-specific award. It is not a demonstration of Multicoin or BoosterCells.
Thunder symbols remain through the bonus. The feature’s remaining-spin rules are listed in the game help.
A round can settle in the game currency while the funding transaction began in another currency. The final game return belongs in the round history; a processor charge belongs in the payment record. Use the two records together when explaining a balance change. This matters especially when a retained-symbol feature shows many interim values before one final total.
Thunder Coins XXL: Hold and Win screens and controls
Start with the occupied positions and the remaining feature counter. A coin label, a jackpot label and a collector can occupy similar-looking positions while performing different roles. Follow the final values shown after a modifier rather than adding the earlier labels again.
XXL, Multicoin and BoosterCells are separate specifications
The May 2025 Hold and Win release should not be described using the newer Multicoin multiplier or BoosterCells storage mechanic. The brand family can support comparison links, but the fact table must remain tied to this edition’s product page and release note.
Thunder Coins XXL: Hold and Win compared with Diamonds Power: Hold and Win
These two titles are connected by their feature family or the way their game states develop. The useful comparison is the specific rule in each row: a shared theme, jackpot label or provider does not make the two games interchangeable.

The numbers behind the round
Start with the total stake, then follow the feature and the amount finally credited. This SM Pay review connects the published rules to the balance records an Australian reader would use to understand a round. Amounts in the worked examples are in Australian dollars; the actual account currency belongs in the game’s own display.
A useful record contains four items together: the selected stake, any separately priced mode, the round identifier and the settled return. A sequence of cascades or respins can look like many actions while still belonging to one original round. Match the complete result to the account history before interpreting the individual animations.
For a payment comparison, keep the game’s result separate from the cost of moving money. A currency conversion, deposit deduction or withdrawal fee changes the amount received by an account, but it does not change the game’s paytable. The related payment guides below explain how to compare those stages without counting the same amount twice.
Follow occupied cells and the remaining counter
The feature begins from a defined board state. Landed bonus symbols can remain in their positions while empty positions continue to take part in the respin sequence. A new symbol, collector or modifier may change both the amount displayed and the counter. Record those as separate changes: the number of occupied cells is not itself a cash value.
Questions about Thunder Coins XXL: Hold and Win
What starts the main feature?
At least one Bonus symbol on each reel opens the feature. Sticky Thunder collectors on the middle reel.
What stays on screen during the feature?
Thunder symbols remain through the bonus. The feature’s remaining-spin rules are listed in the game help. This retained information explains why a later result may depend on earlier stages of the same feature.
Which RTP and prize figure belongs to this edition?
Confirm the version’s help-screen percentage. The published prize reference is Four fixed jackpots rising to 1,000×. Match both to the full game title and selected help-screen configuration.
How should an Australian-dollar example be read?
A$ denotes Australian dollars in this article’s constructed calculations. The actual game can display another account currency. Use the currency code and the total stake shown by that game when translating a stake-based value.
