Thunder Coins XXL: Hold and Win: game rules and edition
Copy the entire title when using a game search. A result ending in Multicoin or BoosterCells is a different edition even if the icon uses the same lightning bolt.

Find the right title and understand its feature
This Boomerang AU guide gives each game a precise catalogue identity and a rule-based overview. A familiar logo or shared character can lead to several related editions, so the full title and developer are kept together throughout the review.
A catalogue entry, a game rules screen and an account promotion serve different purposes. The entry identifies the title, the rules explain play and the promotion defines any external offer. Matching all three is useful when a game family contains several versions with nearly identical artwork.
The related account guides help interpret the surrounding payment and bonus information. They do not change the game’s documented mechanics. Use the comparison table to distinguish editions, then use the current account screens for method support, offer status and available balance.
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.
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.
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.
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 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.
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 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.
After identifying the title, keep the game rules separate from the account’s cash and bonus records. A permitted base game, an excluded optional mode and a completed promotional package are different states. The related Boomerang account guides help identify the screen or written term that answers each question.
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.

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.
