Have you ever played an online slot so rip roaring that your heart has been pumping like it’s going to beat out of your chest? While the Heartburst Slot from Eyecon Games can’t lay claim to be the most adrenaline pumping of slots on the face of its first few spins, it does offer a mouth-watering 100 paylines played out across five reels and four rows, featuring Expanding Wilds and a Lucky 7s Free Spins feature that can be re-triggered up to 15 times. Actually, now we mention it, it does sound pretty adrenaline pumping!


Purple is our base game colour, with deep hues setting the scene nicely for our slots play. Eyecon has gone fully classic in its choice of slots symbols, with 10s through Aces bringing up the rear as our lower-payers and Lemon, Watermelon, Orange, Grapes, Cherries, Bell and BAR doing the honours as the higher-payers. All symbols can appear stacked, making the most out of our 100 payline setup. The BAR symbol offers up 3,000 coins as the top paying symbol for a five-of-a-kind combo. But with stacked symbols and 100 pay-lines, this leaves our potential base game jackpot at a tasty 150,000 credits. Yum.

The symbols themselves stand out nicely against the purple background, drawn and coloured in retro fashion to give the feel of a classic slot fruit machine – only with the added modern twist of 100 paylines. The Heart Wild appears on reels 1, 3 and 5 and substitutes for all game symbols except Lucky 7 Scatters, and any Heart Wild that forms a winning combo pumps into an Expanding Wild. Now we see the bursting hearts of the game’s title, as all symbols in the combo created by the Heart Wild bubble up with tiny hearts themselves. Awwww.


The Lucky 7 Scatters hold the key to our shot at super big wins on the Heartburst slot. Landing three, four or five Scatters launches the Free Games feature to a chorus of “oohs” and “ahs”. We have 15, 20 or 25 free games, depending on our number of triggering Scatters. In solid, classic fashion we bag a payout multiplied by our total bet for Scatter wins, but it is the re-triggering potential that is of real interest. Landing three or more Scatters during the Free Games feature means we will re-trigger the feature, with the potential to achieve this up to 15 times. Should we re-trigger it once we will be over the moon, but anywhere close to 15 and our thoughts will turn to early retirement.


The funky, jazzy riff that accompanies our gameplay and sparkling finishes to our winning payline combinations light up the purple hues of the base game and get our hearts bursting along to the promises of the game’s title. The Expanding Wild wins zhuzh up our regular gameplay, but it is the Free Games feature that we really hunt with vigor. Retriggering the bonus round to any kind of degree has the very real potential of bursting our hearts with the kind of adrenaline that only serious slots wins can provide.
