How We Review Slot Games

We test and rate all slot games across 5 criteria, assigning a score out of 10 for each and an overall score that is an average of the 5. To build an accurate assessment of each game we gather information from the supplier and play in real play or demo mode. Find out more.

HarleCoin is a unique 3-reel slot from Red Tiger that takes its theme from Harlequin characters from medieval Italian culture. This game has a unique format with just one fixed payline on each spin. Symbol values displayed above the reels increase when special HarleCoin symbols land, progressively growing in value until a win is triggered when they re-set. There is also a free spins round where up to 25 free plays are awarded during which HarleCoins land more frequently and symbol values do not re-set between wins.

This is a volatile slot with a 1,076x top win. Spins start at 10p per play.

Testing Notes: Here’s What Happened When We Played HarleCoin

IMPORTANT: To give you an accurate assessment of the games we review our writers play 200 spins. Whilst this is a useful tool to help us review games and to give an example of what might happen when you play, keep in mind that 200 spins is only a very small sample and cannot be used to accurately predict what might happen over another 200 spins. The outcome of all slots play is always random.

Boom Or Bust? Our Session By The Numbers

I played 200 spins on HarleCoin for free on Red Tiger’s website to test the game and this is what happened.

  • Stake Size: £1
  • Start balance: £200
  • End balance: £120
  • Biggest Win: 50x
  • Free Spins Round: 0
  • Session Time: 12 minutes 17 seconds

HarleCoin is a fast game to play. With so few features and just 1 payline you can rattle through 200 spins in no time, so keep that in mind when choosing how you want to approach the stake level. It’s high variance also means you can burn through you balance quickly as I did.

A 50x win on HarleCoin
The biggest win in testing was a 50x

I counted 12 wins in 200 spins – that is just 6% which is lower even than the advertised 20% hit rate. However, due to the configuration of the paytable and the HarleCoin feature, they were a decent size. Amongst those 12 wins were a 50x, a 14x, an 11x and a 9x. So, as expected, infrequent wins, but good value when they came.

The HarleCoins themselves appeared 16 times in 200 spins – that’s just 8% of the time. That is less than I expected, and I never saw one on a Wild, or on the Lucky 7s.

Overall, HarleCoin was a slightly frustrating experience, because the wins were so infrequent. However, they were always at least 2x, and often significantly higher, and for that reason I was still engaged at the end of the 200 spins and this is one I would come back to.

What Our Reviewer Says ...

"A unique slot game that bucks current trends with its simple gameplay. It won't kick out wins that often, but will deliver good value when it does!"

Overall Score: 7.8

Theme & Design

Our Score 9

A Simple Slot With A Mysterious Theme

HarleCoin has a simple, 3-reel layout and an opulent, bronze design with sculpted Harlequein characters appearing either side of the reels, each carrying a giant ruby red gemstone. It has a slightly dark, sinister feel to it but the pay symbols and the background are all beautifully illustrated and the overall vibe is distinctive and high class. A key part of the design is the dynamic paytable which displays current symbol values above the reels. Keep your eye on this throughout the game to see what payouts you can expect.

RTP and Variance

Our Score 7

What is RTP?

RTP (Return to Player) refers to the amount a game will pay out in cash prizes expressed as a percentage of all the money wagered on that game. For example, a 96% RTP means a game will pay out £96 for every £100 wagered. This is an average number and will vary from one session to the next.  Read more here.

What is Variance?

Variance refers to how far a game will deviate from its RTP over time. High variance games deviate a lot and produce uneven win distributions and unexpected windfalls. Low variance games provide a more stable and even distribution of wins. Read more here.

HarleCoin has a slightly under average RTP of 95.71%. It’s not massively below the 96% average though so we can live with it. It’s rated as a medium-high variance slot with an advertised win rate of 1 in 5 (20%) which is itself low too. So, in short, expect infrequent wins, but hopefully when they do land they’ll be of significant value.

Maximum Win

Our Score 6

What Is Maximum Win?

Maximum win refers to the maximum amount a player can win from one spin. It is expressed as a multiple of the stake. For example, where the maximum win is 100,000x, from a £1 stake, the maximum win would be £100,000.  

Perhaps the weakest point about this slot is its maximum win value – just 1,076x. That is very poor for a high variance game like this which we normally expect to offer wins of up to 10,000x at least. If you want better potential I recommend checking out our list of slots with the highest maximum wins.

Symbols and Paytable

Our Score 9

The configuration of HarleCoin is simple to start. There are 3 reels and just ONE payline, straight through the middle.

HarleCoin Rules
The rules and paytable for HarleCoin

But where HarleCoin becomes interesting is in the paytable which is dynamic as the value of pay symbols changes during your session. There are six icons in total, all in a classic fruit machine style – cherries, stars, lucky sevens, clovers, bells and a wild. You’ll see their starting value in a grid that is displayed above the reel. But watch them change on each spin when you collect HarleCoins.

The maximum payline length is just 3, as there are only 3 reels, and the symbol starting values are from 4x for 3 cherries up to 50x for 3 lucky 7s. The wild, as well as substituting for any other symbol to complete a payline, also pays out at 125x for 3 on a line at the start of your spins.

Features and Gameplay

Our Score 8

Onto the features, and they are lite to say the least.

Throughout the game, you should aim to land Harelcoins. These are coins that appear as overlays on symbols on the reels. When one lands it boosts the value of its respective symbol in the paytable above the reels. So, if you land a HarleCoin on a lucky 7, then it will boost the value of the Lucky 7 in the paytable.

HarleCoins can land on ANY symbol, including Wilds.

You can boost the paytable significantly in this way though each symbol has an upper limit value, allowing players to enhance the values of cherries, clovers, stars, bells, sevens, or wilds to 20x, 30x, 50x, 100x, 250x, or 500x the wager.

When a win occurs, then the symbol values re-set to the original starting ones.

Free Spins With Up To 25 Free Plays

There is also a free spins round which is triggered by landing 3 bonus icons which display the words Boost Spins across them.

That gives you up to 25 free spins – the actual number is arbitrarily chosen. Now, the HarleCoin feature is enhanced too – so any icon that isn’t displaying its max value in the grid will ALWAYS land with a HarleCoin booster on each spin. And, in this case, when a win is generated, the values of icons doesn’t reset – so they remain high throughout the round giving you more chance of scoring bigger wins.

And finally …

At the end of your bonus round, the icons remain at the value they are until the next win is triggered in the base game.

The Final Verdict

HarleCoin is an interesting slot because it doesn’t fit the current trend of high max payout, feature-packed games that are currently flooding UK slot sites. Instead it mixes an enigmatic theme with a really simple idea. But it is compelling. It’s not about triggering wins on every 2 or 3 spins, but rather waiting, and building up symbol values before prizes of 5x, 10x or 50x eventually drop. And it does happen. The highlight is obviously the free spins round which looks electric, if you can get there. In short, I think this is a game that has more to offer than its simple configuration and low max win at first suggest. Over to you to decide …

Useful Tips When Playing HarleCoin

Remember, online slots are games of chance, there is NO strategy that can improve your odds of winning. However, reading our review and following these tips will help you get the most out of your time playing this slot game.

1. Start At A Low Stake

My advice would be to start at a low stake. With a hit rate of less than 10% in testing this game showed it can burn your balance quickly. That said, when the win did arrive they were of a good size. But play safe to make your funds last.

2. Keep An Eye Out For Those HarleCoins

There is not much to distract you from the main objective here so keep your eyes out for those HarleCoins. They don’t land that often but when they do they will start to boost your win values nicely.

3. The Free Spins Round Looks Very Promising

With HarleCoins landing on EVERY spin there is no doubt that the free spins round is built to provide the most exciting moments. I didn’t unlock it in testing over 200 spins so be patient and enjoy it when it happens.


4. Only Play At Licensed UK Slot Sites

The slot sites on this page have been chosen because they are licensed under UK law by the Gambling Commission making them safe, fair and secure. Never play HarleCoin at an unlicensed casino.
