Queen of Coins is a Greentube slot with six reels and twenty two-way lines

What the studio actually puts on the record

Greentube keeps a product page for this title, and the useful part of it is a short block of key data. It is short because it is written for the companies that license the game rather than for players, and everything past that block sits behind a client login. What is public is this:

6 reels · 20 win lines · volatility 5 · NovoSDK · Desktop and mobile · themes: Fruits, Coins · key features: Stacked Joker Wild symbols; Cash Spins Feature with Multipliers.

The key-data block on Greentube's own page for Queen of Coins.

Three things about that block are worth saying out loud, because they shape every other page here. It gives a reel count but no row count. It gives a volatility of 5 as a bare number, with no scale printed next to it and no word such as high or medium anywhere on the page — so this site keeps the number and does not translate it into a word nobody wrote. And it gives no return to player at all.

The rows are easy to fill in without guessing. The game draws three symbols per reel, which is what the picture above shows, and one independent write-up records the board the same way, as six reels and three rows. Eighteen is then arithmetic rather than a claim — and eighteen turns out to matter later, because the collecting round uses exactly that number as its finishing condition.

The name belongs to a tarot card first

Queen of Coins is a card in the minor arcana, the one English decks usually print as the Queen of Pentacles. That subject is centuries older than this slot, enormously better documented, and it is what almost anyone writing the three words on their own is talking about. There is no clash of meaning to resolve and nothing to correct — the card simply got there first.

The practical effect is on every heading on this domain. The three words never travel alone here: they go next to slot, next to Greentube, or next to both. It is not a stylistic tic. A page about a fruit machine titled with nothing but the name of a tarot card is a page that will be opened by people who wanted the card and closed by them a second later, and that helps nobody.

The same care is worth taking with the artwork. The crowned disc that runs the feature is a coin with a crown stamped into it, not a portrait of a queen, and the game has no queen character in it anywhere. The crown is a marker that separates the feature symbol from the fruit — nothing more mystical than that.

How a round is judged, from the left and from the right

The symbol set is deliberately old-fashioned: cherries, lemons, oranges, plums, grapes, strawberries, watermelons, bells, BAR tiles and red sevens, plus the Joker and the crowned Coin. Nothing in that list needs explaining to anyone who has ever stood in front of a pub machine, which is the point of it.

What is not old-fashioned is the way the twenty lines are read. Lines 1 to 10 run the normal way, beginning on reel one and paying leftwards to rightwards. Lines 11 to 20 are the same twenty patterns read backwards, beginning on reel six. One fixed set of twenty, two directions — which means both outer reels are starting reels, and a sequence that builds from the right counts just as much as one that builds from the left.

Two independent write-ups of this title describe the same arrangement, one of them calling it double-direction wins and splitting the twenty between the two directions exactly as the figures here do. It is the single feature that most changes how the base game feels: with six reels and no direction to favour, far more of the board is live on any given spin than a twenty-line count would suggest.

Coins are counted, not lined up

The Coin ignores the line system completely. It does not sit on a payline, it is not helped by the Joker, and it does not need to be anywhere in particular — it is counted across the whole screen. Get 6 of them in view and the Cash Spins round starts, and the twenty lines stop mattering until it is over.

Inside the round the Coins already in view are held, the rest of the board spins again, and a counter under the reels tracks how many attempts are left. Every new Coin that lands is held too and refills that counter, which is why a round that begins slowly can still go a long way. Each held Coin is carrying something: a cash amount, a multiplier, or one of the four named displays above the reels.

Fill all 18 positions and the game adds the GRAND display on top of everything collected. That is the only reason the board size matters as a number rather than as a shape — eighteen is the target, and the number of blanks left is the progress bar.

Where a free round can be had, and where it cannot

There is no game on this site. No demo window, no embedded client, and no button here dressed up to look like one — the only outbound link on any page is the operator button at the top.

Away from here the picture is uneven, and it is worth knowing that before going looking. One games catalogue does list a free round of this title, run through a third-party launcher on virtual credits, and publishes a list of territories alongside it — so whether it opens depends on where the reader is. Greentube runs its own play-for-fun site, which carries this title among a large library on virtual credits behind a sign-in. Greentube's business-facing product page offers nothing playable at all.

That is the honest shape of it: free play for Queen of Coins exists in places, it is not a property of the game that travels everywhere with it, and promising a reader otherwise would be writing a cheque that somebody else has to cash.

What the four displays above the reels are worth

GRAND, MAJOR, MINOR and MINI sit across the top of the screen in red, green, blue and purple, and they stay visible through the base game and through the feature. They are not a separate bonus game: a collected Coin can carry one of those names, and a completed board adds the GRAND.

Greentube publishes no figures for them. What can be said — and it is this site's own observation rather than anybody's published rule — is that on two screens recorded here at two very different stake sizes, all four displays held the same relation to the stake: roughly 6,250x the total bet for GRAND, 225x for MAJOR, 75x for MINOR and 25x for MINI. Two screens are two screens, not a specification, and an operator may well configure them differently. Read it as a reason to check what the displays say at the stake being played, not as a promise.

None of this is a reason to play, and nothing here is advice to. It is paid entertainment with a built-in cost, the stake is gone the moment it is placed, and the only sensible amount to put on it is one that would not matter if it never came back. The button at the top of this page opens an operator's site in a new tab and asks whether the reader is 18 before it does — that link is here too, and this site is paid a commission when it is used.
