Start here:Expanding Wild Re-spins Set all 100 paylines active at the minimum per-line bet for your first 20 spins. Watch which reels (1, 3, or 5) land the Heart wild most often. Heart wilds only appear on those three specific reels, so knowing which one fires first helps you mentally track your proximity to a three-reel expanding wild scenario.
The Ice Cube Wild can land on any of the five reels during the base game or during a re-spin. When it lands, it expands vertically to cover all three rows on that reel and locks in place. The remaining unfrozen reels then re-spin once for free. Any cluster wins formed with the help of the expanded wild are paid out after the re-spin resolves.
How to Play Heartburst — Step by Step

Symbols and Paytable
Heartburst uses a classic fruit machine symbol set with four card royals at the bottom, seven fruit/classic machine symbols in the middle, and the two special symbols.
Low-value card royals (J, Q, K, A): The standard paytable filler; need three or more on a payline for small wins.
Classic fruit machine symbols (ascending value): Lemon, cherry, orange, grapes, watermelon, bell, bar. The bar is typically the highest-paying regular symbol in classic Eyecon fruit machines. Exact credit values for each are in the in-game paytable — open via the question mark button.
Heart — Expanding Wild:
The expansion and tripling are automatically conditional on the Heart contributing to a win. If a Heart lands but doesn’t contribute to any winning combination, the expansion still occurs but the triple multiplier only applies where the Heart substitutes into a winning payline.
Eyecon’s official description confirms the sequence: “Heart symbols EXPAND to fill their reel before line wins are awarded. Prizes are TRIPLED when one or more Heart symbols substitute.”

During free games, the same paylines and bet per line from the triggering spin carry over. The Heart expanding wild remains fully active with its 3x tripling behaviour — free games are where the expanding Heart’s multiplier compounds most effectively.
The Lucky 7 scatter also pays directly: 3 scattered Lucky 7s = 5x your total bet; 4 = 15x; 5 = 300x (your total bet, not line bet — a significant distinction on a 100-payline game).

Follow UsDesign and Theme
A dark purple background with clean, colourful fruit symbols on the 5×4 grid. The aesthetic sits somewhere between a vintage cabinet and a modern digital release — the fruits look genuinely juicy and well-rendered (watermelon, cherries, oranges all pop against the purple background), while the card royals maintain their classic proportions.<
< img src="https://www.blackspins.com/wp-content/uploads/2020/10/Insta.png" alt="Instagram">Heart animations when the wild expands are crisp and fast. The reel-filling expansion is a clear visual event without introducing lag, which matters on a 100-payline game where win calculations involve many simultaneous payline checks.
<Pros:
- Expanding Heart wild on reels 1, 3, and 5 with automatic 3x tripling is a powerful, clean mechanic — three simultaneous expanding Hearts covers the entire grid with tripled wild coverageCasino Games
- 100 variable paylines on a 5×4 grid gives maximum coverage breadth for wild expansionsSlots
- 3,000x maximum win is a credible ceiling for the expanding-and-tripling mechanicJackpot Games
- Free games retrigger up to 15 times — lengthy free games chains are achievableArcade
- Lucky 7 scatter pays 300x total bet for 5 of a kind anywhere — meaningful direct scatter payouts at any stakeScratchies
- Gamble Feature allows up to 5× consecutive doublings — useful for players who want to compound smaller winsOnline Pokies
- RTP 95.63% — one of the stronger Eyecon titles at Blackspins; above Haunted Hallows (90.74%), Very Merry Christmas (95%), Happy Birthday (95.40%)Mobile Casino
Cons:
VIP- RTP 95.63% is below the 96% benchmark — the Blackspins header rounding to 96% creates a slight discrepancy players should be aware ofNews
- Heart wilds restricted to reels 1, 3, 5 means reels 2 and 4 never deliver expanding wilds — those two reels only contribute regular symbol winsPayment Methods
- High volatility on a wide-payline game means base-game sessions can feel unremarkable between Heart wild eventsFAQ
- 3x tripling only applies when the Heart Terms & Conditionssubstitutes in a winning combination — a Heart that expands on a reel but doesn’t substitute (because the other reels already complete the combination without needing substitution) doesn’t triple that winPrivacy Policy
- Classic fruit theme is inherently less varied than modern slot aesthetics — the symbol set is the same across dozens of similar titlesContact Us
Bottom line: Heartburst is a well-executed Eyecon fruit machine with a genuinely interesting expanding wild mechanic. The Heart’s automatic reel-expansion followed by prize-tripling turns what would be a standard wild substitution into a wide-coverage, multiplied event — and three simultaneous Hearts across reels 1, 3, and 5 is one of the cleaner high-impact scenarios in Eyecon’s catalogue. The 95.63% RTP is decent for a high-volatility classic-style title. Play all 100 paylines even at minimum stake, keep an eye on the three Heart-eligible reels, and let the expanding wilds do the work.
