About Game

Thunder Coins XXL Multicoin Demo

A Storm Over a Fruit Machine

One spin early in the Thunder Coins XXL Multicoin demo showed the whole idea. A blue Thunder Coin dropped onto the middle reel, the five coins beside it went quiet on their own, and the lot came in as one 10.00 collect, 10x the stake off a single spin. That sweep is the engine of this 3-reel slot. Playson has wrapped a classic fruit machine in a thunderstorm, and while the fruit and BARs deal only in small change, it is the coins and the two feature coins that harvest them that carry the game. The new face this time is the Multicoin, a second collector that pulls in the same values and adds a multiplier on top, and the free demo makes it easy to see it in action.

Meet the Two Collectors

Where Each Coin Lands

The paying falls to a trio of coins, and each keeps to its own part of the board. The plain gold Coin drops on reels 1 and 3, carrying values from 1x up to 8x the bet, and it sits idle until a collector picks it up.

The two that matter, the blue Thunder Coin and the red Multicoin, appear only on the middle reel, and neither pays on its own either.  What they do is reach out and scoop up every coin value on the reels.

Thunder Coin Sweeps the Board

Land a Thunder Coin with any coin on the board, and the collecting begins. The Thunder Coin gathers the value of every coin on the reels, jackpot coins included, and puts the sum straight onto that spin. From our experience, it is the workhorse of the two, the one we saw most, and a clean row of gold can hand it a tidy return from a line that had paid barely a thing by itself.

Multicoin Collects & Multiplies

The Multicoin is the new coin, and the reason the game’s name grew.  It works like the Thunder Coin, but goes a step further, drawing in the same values, jackpots and all, then multiplies its own haul by a random figure, x2, x3, x5, x7, x10, x15 or x20.

In regular play, a drop of plain coins with no collector among them can also have a Multicoin added to reel 2 at random, setting off its feature or the bonus.

In the bonus, it can even pull fresh multipliers on later respins.

The Thunder Coin has taken the 1.00 and 3.00 from the right reel for 4.00, and below it, the Multicoin’s counter is still climbing past 15.25 on its way to 20.00, a x5 on those two coins.

Respins That Feed Every Collector

Coins on reels 1 and 3 arriving with a Thunder Coin or Multicoin open the Bonus Game, a hold-and-win round of respins. Only coins fall in this mode, and the collectors lock onto the middle reel where they land.

The round starts with 3 respins and resets to 3 with every fresh coin. This is where the collect really tells, because each value that lands is added to every collector on the reel at once, so with a few up there, a lone value can be banked several times over, up to five when the reel is full. Once the respins run dry, the collected totals drop into the win.

Bonus Game respins with three Thunder Coins reading 11.00, 11.00 and 7.00 and a Minor jackpot coin on the right reel Three Thunder Coins locked on the middle reel at 11.00, 11.00 and 7.00, and the Minor coin on the right is about to add its 30.00 to each of them, the rule that makes this round climb.

Paying to Skip the Wait

Two extra bets sit by the spin button, but only one runs at a time.

  • Double Chance adds half a stake again, at 1.5x, and doubles your odds of a bonus.
  • Thunder Spin asks 5x and gives more back, guaranteeing a Thunder Coin or Multicoin every spin and tripling the odds of one.

The buy menu also offers three prices: a 75x round holding at least one feature coin, a 175x Super Bonus with a Thunder Coin and a Multicoin both assured, and a 250x Multicoin Bonus that starts on two Multicoins. Whichever you buy, more feature coins can still land on top.

Pile of Gold Fills the Gaps

This base-game feature can be set off by any coin that lands. When it fires, a heap of coins drops onto the reels and adds whatever the bonus was still missing, gold on the outer reels or a Thunder Coin or Multicoin in the middle, enough to start the Bonus Game from a spin that was never getting there on its own.

Jackpots Arrive by Coin

Four fixed jackpots line the top of the board, and a feature coin is the only route to them. Should a Grand, Major, Minor or Mini coin appear inside a collect, its value is swept in with the rest, worth 15x for the Mini, 30x for the Minor, 100x for the Major and 1,000x for the top tier against the total bet. There is no ladder to climb and no wheel to spin, so a jackpot rides in on a coin that happens to land.

How to Play

15 Lines on 3 Reels

Wins run across 15 fixed lines, reading from the first reel along touching positions, with only the best line counted. The grid is compact, 3 reels wide and 5 deep, so fruit combinations come and go fast between coins. Stakes run between £0.20 and £100.00 a spin.

Slot Paytable

The fruit and BAR symbols pay at the low end, and the coins are absent from the table, since their value only counts once a collector takes it.

Symbol 3 of a kind
777 (Wild) 30x
Bells 10x
BAR 8x
Watermelon, Grapes 4x
Orange, Plum, Lemon 1x
Cherries 0.5x

Every line pays for a matching trio, the most a 3-reel board allows, and the values are multiples of one spin’s stake. The 777 also plays as the wild, filling any fruit, bell or BAR to finish a line but never a coin. The return is 95.65%, with a 94.65% build at some casinos, and the volatility runs medium-high.

Ultimate Slots Verdict

Once the storm settles, what is left is a coin collector, and a good one. The collect is what you come for, and it earns the billing, with a busy bonus building a real head of steam before the respins run out. The Multicoin is the piece the earlier Thunder Coins XXL went without, and this also puts a multiplier on its haul instead of only banking it. If you like watching a collect build, with the storm and the coin showers making even small wins feel like an event, this one is easy to warm to. Big-number hunters are the exception, with a 1,000x top all the game reaches. Judged on what it sets out to do, it stands up well.

3.6/5 Very Good

What We Like

  • The collect gives the bonus momentum, a round that keeps growing for as long as coins keep dropping.
  • The Multicoin can land in regular play, as well as the bonus, so the multiplied collect is not locked behind a trigger.
  • Getting to the bonus is flexible, with two extra bets and a tiered buy menu instead of one fixed entry.

What Could Be Better

  • Between coins the fruit reels go quiet, with the best line only the 30x row of 777s, so a stretch with no collector comes to very little.
  • The Grand jackpot doubles as the game's cap, which runs low for a coin collector, so even a good run stays well short of a headline number.
  • The guitar riff behind each spin cuts out a few seconds in, so short of running auto-spin it keeps starting over.

Detailed Review

A Big Production on a Small Grid

The first thing this slot does is make noise. It opens on a thunderclap and a fork of lightning, the paylines themselves picked out in electric blue across the grid, and even at rest, the screen never fully stills, with electricity arcing from behind the reels to the edges of the frame. Wins land with a crack of thunder, the winning symbols wired together in yellow and blue while the rest dim back. The base game can still spike on its own, and a screenful of 777s and BARs paid 16x during our session. For a 3-reel classic, it feels like a big production.

What the Collect Is Worth

Beneath the storm, the game itself is the collect. An ordinary coin just waits until a feature coin reaches over and takes it, and the bonus is where that pays off, coins locking in place while the collectors bank them across the respins. One demo round climbed to 131.00 this way, a Minor jackpot coin landing among the gold, building in the steady, unhurried manner these rounds manage when two collectors are working at once.

Lighter Than Its Coin Cousins

This is not the studio’s only coin collector, but it plays like a lighter cousin to its bigger coin games, trading their higher top ends for rounds that arrive more often and resolve quickly. The demo keeps all buy options and extra bets enabled, so even the 250x round can be tested in free play.

Frequently Asked Questions

Both are collectors, so the split is in the finish. The Thunder Coin banks what it gathers straight away, while the Multicoin stacks a multiplier of up to x20 on top, which makes it the scarcer and the more valuable of the pair.
Any coin landing before the bonus may set it off, and no meter leads up to it. It adds the coins the bonus was short of, so the round begins on that spin.
It keeps the collect readable. Value coins fall on the outer two reels and the collectors on the centre one, and the bonus opens only when both sides show at once.
Yes. A jackpot coin pays only when a Thunder Coin or Multicoin sweeps it up, so no tier can land unless a collector is on the reel.
No. Double Chance and Thunder Spin only affect how often the bonus turns up, and Thunder Spin also promises a feature coin each spin. The coin values and jackpots hold firm, so the top of the game is unchanged.
The 250x Multicoin Bonus is the surest, as it opens with two of them. The other two are a gamble on the red coin, as the 75x guarantees only a feature coin of some kind and the 175x pairs a single Multicoin with a Thunder Coin.
