HarleCoin Online Slot Review

The HarleCoin slot is a 3-reel, 1-line game, filled with jeweled symbols. The sparkling style matches the dazzling gameplay which sees special coin symbols boosting the value of others. You can increase symbol multipliers to a huge 500x to grant the biggest prizes. It’s easier to collect multipliers during a free spins bonus feature, when coins appear on every symbol.

You can enjoy this innovative slot on a PC or mobile at online casinos featuring the Red Tiger range. It’s a game with a medium level of volatility and payback percentage of 95.71%. Land the perfect mix of symbols and multipliers and you can win up to 86,080.00 at the maximum bet.

How to Play the HarleCoin Slot Machine

If you think a 3-reel, single-line game sounds a little dull, look again, as the HarleCoin slot features gorgeous graphics and thrilling gameplay. The symbols look like precious jewels, and you’ll encounter lucky clovers, purple bells, cherries, stars, and red 7s on the reels.

Golden harlequins smile at you from the sides, and like many 3-reel slot games, the paytable sits fully in view. This reveals how many times your bet each pays out when crossing the payline, and it becomes even more useful when symbols start to multiply in value.

You can play the HarleCoin slot on a PC, iOS, Android, or Windows mobile for between 0.10 and 80.00 for each spin. It’s an easy game to set up, with clicks on Plus and Minus tabs all that’s needed to select a bet level. Auto and Turbo buttons set the reels spinning on their own and speed things up.

Although symbols values are always on display, it’s still worth checking out the bonus table, via a click on the 3 small lines at the top of the game. This outlines the unique bonus features of the HarleCoin slot machine.

Free Spins & Other HarleCoin Slot Bonus Features

Three diamonds are the wild symbol of the HarleCoin slots game, and also the most valuable, at 125x your bet. Look out for special harlequin-embossed coins overlaying random symbols, as these are key to the big multipliers. Each coin boosts the value of the relevant symbol, and if more examples of the same symbol land with coins on them, the values rise even further. However, once you get a win from a symbol, its value resets.

The paytable at the top of the reels isn’t just there for decoration, as it means you can keep track of what each symbol is currently worth. If a coin overlays the same symbol type six times without it being in a win, multipliers rise by 20x, 30x, 50x, 100x, 250x and finally, 500x.

Any 3 bonus symbols on the line will trigger a Boost Spins free games feature. You get a random number of up to 25 free spins, and all symbols not already at the maximum multiplier now come with coin overlays.

This makes it inevitable that symbol values increase until they are in a win. Multipliers don’t reset when the symbols are in a win, and once the free spins end, they carry across to the base games. Additionally, some of our recommended online casinos are offering free spins no deposit bonuses.

HarleCoin Slot Maximum Wins, Average Returns, & Volatility

The maximum possible win is equal to 1,076x your bet, or 86,080.00 when you play with 80.00. This is lower than many other slots, and the only real disappointment here, but on the positive side, it makes the maximum bet easier to reach. HarleCoin is a medium volatility game where over the long-term, the return to players percentage is 95.71%.

Our HarleCoin Online Slot Verdict

The sparkling symbols and ingenious mechanics of the HarleCoin slot will ensure long-lasting popularity. It can be quite difficult to land enough coins before a symbol is in a win, so getting to higher multipliers won’t happen too often.

Once the free games start, it clearly becomes far more likely that you get a big win, although we were a little disappointed at the maximum 1,076x potential. But if you enjoy games that offer something different to others, and like the colourful gems theme, then the HarleCoin slot could be just what you are looking for.

It’s available at the best Red Tiger slots sites, so sign up, collect their welcome bonuses, and play the HarleCoin slot machine today.


Small coins, decorated with harlequins, land on top of random symbols. The value of the symbol then increases, and if further coins land on the same one the multiplier continues to increase. You can boost the value by up to 500x, but they reset once the particular symbol has been in a win.

Land 3 bonus symbols on the payline to claim a random number of free ‘Boost Spins.’ The maximum is for 25 extra spins, but however many you get, the coin overlay feature applies to all symbols, so it’s far easier to build huge win multipliers before the bonus games come to an end.

Follow our guide to the best online casinos. You can play the HarleCoin slot machine at these sites, and also collect the best sign-up bonuses when you join. A huge collection of other games awaits at the top casinos.

This is a medium volatility game. Compared with other slots, the HarleCoin slot machine pays average-size prizes at an average frequency. High volatility games pay bigger prizes, but less often, and the opposite is true with low variance slots.

You can play the HarleCoin slots game for as little as 0.10 per spin. The maximum bet is 80.00, so it’s a game that should cover most budgets, and there are lots of options in between these limits. Getting started is easy, with simple controls designed for ease of use on desktop and mobile platforms.

The symbols are crystal-style versions of classic fruit machine icons. Play the HarleCoin slots game and you’ll encounter crystal clovers, cherries, bells, stars, and red 7s. You win by landing 3 symbols of the same kind, or matched symbols plus the wild, across the single payline.

The maximum possible win from the HarleCoin online slot is equal to 1,076x your bet. If you play at the highest stake of 80.00, you can win a cash award of 86,080.00, which is lower than in many other slots.

Similar games include the Perfect Gems online slot from Pragmatic Play, where reels can expand to give you up to 21,609 ways to win. An unlimited win multiplier is active throughout a free spins bonus round, and you can win up to 5,000x your stake.

The HarleCoin slot machine comes from Red Tiger. Other slots in this Spanish developer’s range include Primate King, Cash Ultimate, and Piggy Riches Megaways. You can play these and many more at the best desktop and mobile casinos that carry the Red Tiger portfolio.

Red Tiger launched the HarleCoin slot machine on 1st June, 2021.
