Greentube goes for something simple with Queen of Coins. After all, this 6-reel, 3-row slot is based on the classic fruit machine stylings, with plenty of familiar symbols forming just 20 paylines. The coins of the title come into play with the hold and spin-style Cash Spins, where you can take the chance to win one of 4 jackpot prizes. Now join us as we tell all in our definitive Queen of Coins review.



As we’ve mentioned in our introduction, Queen of Coins is a simple slot set on 6 reels and 3 rows. It offers a total of 20 fixed paylines formed in the traditional way, which is to say landing at least 3 matching symbols on adjacent reels. Paylines always start from the leftmost reel, moving from left to right.
Greentube fails to let one know what this slot’s RTP is. In fact, the game’s Paytable or Help pages lack any technical information regarding RTP, volatility, or hit rate. The most you can win from this slot game is 6,250x the stake, a payout you can get through the Cash Spins bonus feature. Betting starts from £0.40, which is a bit high especially from a game in the fruit machine genre.
There are lots of different online casinos where you can play Queen of Coins. Here is my pick of the best slot sites:
Queen of Coins features no surprises when it comes to the graphics. The game is set on a theatrical background, with deep scarlet curtains preparing us for the show. The reels are in a brighter shade of red, and hold colourful symbols. There’s little in terms of audio, however, outside of simplistic reel sounds and a little chime that plays whenever a coin scatter hits.
There are 10 classic symbols on the reels - the seven, bell, Bar, melon, grapes, strawberry, orange, plum, lemon, and cherries. The jester hat wild can substitute for all of these paying symbols to form more winning combinations. Last but not least are the coin scatters, which will trigger the Cash Spins feature if you land 6 or more anywhere on the reels.
Let’s see the values of the paying symbols.

Cherries
5 - 1.25x / 4 - 0.25x / 3 - 0.125x

Lemon
5 - 1.25x / 4 - 0.25x / 3 - 0.125x

Queen of Coins is an HTML5 slot, making it perfectly playable on any device that can run an internet browser. The bright visuals actually make this ideal for mobile devices, even if its wide 6-reel format might look a bit cramped if playing on a smartphone in portrait mode. As such we recommend playing this one in landscape when you’re on the go.



Queen of Coins has one bonus feature, the Cash Spins feature. Let’s see what this involves.
Land 6 coin scatters anywhere on the reels to trigger the Cash Spins feature. This is a hold and win feature where you get 3 respins with which to land as many more coins on the reels as possible. Any landed coins lock in place for the duration before resetting the number of respins back to 3. Coins can hold cash values ranging from 0.25x to 6.25x the bet, as well as a Mini, Minor, or Major jackpot. The Mini jackpot is worth 25x the stake, the Minor 75x, and the Major 225x. Then there are multipliers, which can boost the values of all coins on the reels by 2x, 3x, or 5x.
The Cash Spins feature ends once you either run out of respins or fill all reel positions with coins. If you manage to fill all the reels then you’ll win the game’s Grand prize of 6,250x the stake. Once the round is over the values on all coins are added up and the total applied to your bet to bring about the final payout.

While a perfectly decent slot, Queen of Slots has little that distinguishes it from an overcrowded slot arena. After all it’s just a 6-reel take on the fruit machine format, and while the Cash Spins bonus feature is fun enough it’s just that. More concerning is the fact Greentube fails to provide any RTP data for this slat, meaning we’re not sure how fair this game’s spins actually are. It all makes for an ultimately unmemorable game that this reviewer can easily discard, never to play again.
