Heart Attack by Giddyup Slot Overview
Heart Attack by Giddyup brings Valentine’s charm to life with glossy hearts, roses and a winged heart character. Its Wild multipliers share a mechanical link with Olympus Doubles, but here Cupid’s arrows build sticky heart multipliers during Love Arrows.
The Love Meter adds depth to Love Arrows: arrows build towards upgrades that strengthen every heart and award extra spins. High volatility accompanies a maximum win of 5,000x the bet. Explore the romantic twists in the free demo on BonusTiime, with no deposit or account needed.

Heart Attack Slot Features

Heart Attack packs Cupid Strike, Bonus Chance, Heart Rain, Love Line, Love Attack, Love Arrows, Heart Lock and Eternal Love into one feature-rich slot with sticky multipliers, linked reels and hold-and-respin play.
Cupid Strike
Cupid Strike can trigger on any spin and fires 1-3 arrows before the win is counted. Each arrow turns symbols into WILDs on reels 2-5, but the WILDs do not carry multipliers in this mode. It changes the board before wins are settled, which keeps the base game lively.
Bonus Chance
Bonus Chance is an every-spin mode that pays exactly like the base game and changes nothing on the reels. Its only effect is the trigger rate: Love Arrows then starts on about 1 spin in 156, against 1 spin in 259 without it.
Heart Rain
Heart Rain starts with the first screen paying like the base game, then every winning symbol bursts and new symbols rain down. Screen multipliers rise from x1 to x36, then stay at x36 for any further rains, until a screen shows no win or the sequence reaches 20 rains. Bonus pays only on the first screen.
Love Line
Love Line turns one whole row into the same symbol, so that row always forms 5 of a kind. The arrow carries a heart multiplier of x2, x3, x5, x10, x25 or x100, and the win for that symbol is multiplied by the heart before other wins and Bonus pay are added.
Love Attack
Love Attack links 2 to 5 neighbouring reels and makes them land with the same symbols. Every linked reel gets a heart of x2, x3, x4, x5 or x10. Any win that reaches linked reels is multiplied by the sum of those hearts, while wins that miss them and Bonus pay stay unchanged.
Love Arrows
Love Arrows is the free spins bonus, triggered by 3, 4 or 5 Bonus symbols and also started by features when the rules allow it. Natural triggers award 10, 12 or 15 spins, while buying Love Arrows starts with 10 spins; each spin can shoot 0-3 arrows that leave sticky hearts on positions. Those hearts can build up and strengthen later wins.
Pick a Heart
Pick a Heart opens every Love Arrows bonus and reveals the prize before the feature begins. The choice can award +2 or +4 spins, or place a x3 or x5 heart already on the reels. The pick only reveals its prize, which is decided when the bonus starts.
Love Meter
Love Meter tracks the arrows fired during Love Arrows and Eternal Love. At 6, 14 and 24 arrows, every heart on the reels grows by +1 and you gain +2 spins. In Love Arrows, 3 or more Bonus symbols during free spins also pay their value and add +5 spins.
Heart Lock
Heart Lock is a hold and respin bonus on all 20 positions. It starts with 6 prize hearts, each worth 4x, 6x, 10x, 16x, 30x, 60x or 200x the bet. You get 3 respins, and every new heart resets them to 3 while locked hearts stay in place.
Two special hearts change the round further. x2 doubles every prize on the reels, while Collect adds the value of all other prizes on the reels to its own position. If all 20 positions fill, Heart Lock awards 900x the bet as the Love Full House.
Eternal Love
Eternal Love is the second free spins bonus and starts with 10 free spins plus Pick a Heart. It also opens with 2 sticky Wild hearts at x1 on reels 2-5. After each spin, Cupid can shoot 0-2 arrows to add new sticky Wild hearts or boost ones already on the reels.
These sticky Wild hearts substitute for every symbol except Bonus, and they multiply any win that passes through them. The bonus also uses the Love Meter system, so arrows can raise every Wild heart and award +2 spins at the set levels. 3 or more Bonus symbols add +5 spins.

Heart Attack Slot Review
Heart Attack uses a bright Valentine look with pink, red and gold layered over hearts, roses and Cupid art. The identity comes from the glossy presentation and the way each feature leans into romance without losing clarity. The result feels polished, playful and instantly readable.
The real hook is the feature stack. Heart Rain, Love Line and Love Attack each reshape the base game, while Love Arrows and Eternal Love add sticky hearts and growing multipliers. High volatility and a 5,000x cap keep the stakes sharp, but the buy menu also makes the game feel very feature driven.
Heart Attack combines multipliers, retriggers and bonus layers. The upside is clear structure and variety. The limit is the same high volatility that can leave the base game quiet between bigger moments, even with the 96.20% RTP.

Heart Attack Slot FAQ
How Does Heart Attack Trigger Its Free Spins?
Heart Attack triggers Love Arrows from 3, 4 or 5 Bonus symbols. Natural triggers award 10, 12 or 15 free spins, while Love Arrows bought through Features opens with 3 Bonus symbols and starts with 10 free spins. During free spins, Cupid shoots arrows, leaving sticky heart multipliers on positions for later wins.
What Does Each Buy Option Cost And Give?
The buy menu offers Love Arrows at x100 the bet, Heart Lock at x250 the bet, and Eternal Love at x500 the bet. Every-spin options cost Bonus Chance at x1.25 the bet per spin, Heart Rain at x2 the bet per spin, Love Line at x10 the bet per spin, and Love Attack at x30 the bet per spin.
What Is The Max Win In Heart Attack?
Heart Attack caps every round at 5,000x the bet. The game rules say a round stops immediately when that limit is reached, and any remaining free spins or rains do not continue. The maximum win applies in every mode, so the ceiling stays the same across features.
Can You Play The Demo For Free?
Yes, the free demo is available on this BonusTiime page. You can try Heart Attack without a deposit or account, which makes it easy to test the base game, the feature system, and the buy options. The demo version uses the same published rules and figures.
How Does The Signature Mechanic Work?
Heart Attack builds around Ways, plus Wild multipliers and several feature modes. The base game uses 1024 ways on 5 reels and 4 rows. Wild lands on reels 2, 3 and 4, substitutes for every symbol except Bonus, and can carry x2 to x10 multipliers that add together.
