This review covers the 2025 Hold and Win edition. The similarly named 2026 Multicoin and BoosterCells releases need separate comparisons because their added mechanics are material.

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.

|---|---|---|
| Developer | Playson | Playson |
| Layout | 3 columns × 5 rows, 15 lines | 3 columns × 3 rows, 5 lines |

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.
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.
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.
A game review explains the product, while a reward comparison explains the proposed account benefit. A cashback credit, fixed-stake spin package and deposit match cannot be compared by their headline numbers alone. Identify the balance category and calculation period before combining a game choice with the conditions of an offer.
A comparison built around the actual edition
Casino Ivan’s review separates the game’s edition, its ordinary rules and its optional modes. A suffix such as XXL or Super Scatter can change the feature materially, so the full title is the starting point for a meaningful comparison.
The specification table deliberately separates return information from a maximum win. The former describes a long-run mathematical configuration; the latter is a ceiling or named prize condition. Neither is an observed result from this editorial review. A comparison becomes clearer when each number remains attached to the property it describes.
An offer-specific spin package adds another layer: eligible edition, fixed stake, expiry and winnings treatment. Those conditions come from the account promotion, while the game mechanics come from the developer. Compare each layer separately before combining them into a single view of a proposed offer.
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.
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.


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.
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.
