Hearts Highway: Slot Overview

Alongside ignoring trends and formulaic design to build fresh gambling experiences, Push Gaming also knows how to take familiar slot concepts and package them for a wide audience. A good case in point was 10 Swords, which borrowed the instant prize win scatter style seen in hits such as 9 Masks of Fire, then layered on extra tweaks to make it feel new. Hearts Highway carries that momentum forward, acting as a kind of offshoot to 10 Swords with a couple of mechanical upgrades.

New mechanics are great on paper, but they can miss the mark if the presentation is dull. Hearts Highway avoids that pitfall: although it leans on classic slot imagery, it’s framed in a “far-flung future” where “cyborg patrons” are treated to a simpler era. Push Gaming doesn’t overplay the cyborg theme, yet the game still delivers an eerie, atmospheric vibe that calls to mind Simon Stålenhag’s (Tales from the Loop) art—hazy, futuristic, and strangely familiar. The retro synth soundtrack fits the mood perfectly. Overall, Hearts Highway is a “classic slot” from a studio known for sitting near the top tier of imaginative audiovisual design.

Striking a balance between vintage and modern, Hearts Highway runs on 5 reels with 3 rows and 20 paylines. Above the grid is a prize list showing payout values and how many Heart symbols are needed to claim them. To play, bettors can choose stakes from 10 c to $/€100 per spin, plus the Push Bet and a bonus buy option. Turning on the Push Bet increases the stake by 20% and boosts the chance of winning the feature by 74%—a nicely specific touch from Push. With medium-high volatile behaviour, Hearts Highway offers a default RTP of 96.43%, or 96.95% when the Push Bet is enabled.

Push Gaming sticks to the classics for Hearts Highway’s paytable. Standard symbols include grapes, limes, watermelons, cherries, green BARs, red BARs, bells, and sevens. A 5 OAK line returns 3.5 to 30 times the bet. The diamond acts as a wild and can land on every reel. It pays the same as the 7 symbol when forming wild wins, or it can substitute for any regular paying symbol.

Hearts Highway: Slot Features

Hearts Highway is built around scatter-style instant prize wins, but it packs in more moving parts than many games in the same lane. The feature set includes Red Heart symbol wins, Slot Machine symbols, a Heart Slot feature, free spins, the free spins Heart Slot feature, and a bonus buy.

Red Heart Symbol & Slot Machine Symbol

Red Hearts function as instant win bet multiplier symbols. They can appear in both the base game and during free spins. Landing 4 or more anywhere on the reels awards a prize. The payout is 2x, 5x, 10x, 25x, 100x, 1,000x, or 10,000x when 4, 5, 6, 7, 8, 9, or 10 Red Hearts are visible. The Slot Machine symbol can show up on the leftmost or rightmost reels in the base game or in free spins. This Mini feature activates when a Slot Machine symbol lands at the same time as a Red Heart symbol. The Slot Machine then spins a 3-reel matrix with one symbol per reel, where each reel can land Red Heart symbols or blanks. Once the feature ends, a prize may be awarded depending on the number of Heart symbols on the main reels and how many Heart symbols landed during the Mini feature.

Heart Slot Feature

If 2 Slot Machine symbols land on the leftmost and rightmost reel, the Heart Slot feature begins. It plays out on a 6-reel matrix with one symbol per reel, producing Red Heart symbols, Double Red Heart symbols, or duds. Any Red Heart or Double Red Heart that lands becomes held. The Heart Slot keeps spinning until no additional Red Heart or Double Red Hearts appear. After that, the game evaluates the result and pays out based on the number of Hearts on the main reels and the outcome of the Heart Slot feature.

Free Spins

Landing 3 scatter symbols awards 10 free spins, while 4 scatters award 12 free spins + 1 Golden Heart above reel 2, 3, or 4. A 5 scatter trigger grants 15 free spins + 3 Golden Hearts above reels 2, 3, or 4. Golden Heart symbols appear only in free spins on reels 2, 3, and 4, where they substitute for Red Hearts. When Golden Hearts land, they are collected into the Golden Heart Meter above the relevant reel, then they’re replaced by Red Hearts. Once 3 Golden Hearts are collected in a meter, an additional free spin is awarded, and the reel beneath becomes filled with locked Red Heart symbols for the remainder of the feature.

Free Spins Heart Slot Feature

The free spins Heart Slot feature uses a 6-reel matrix with one symbol per reel, and can land Red Hearts, Double Red Hearts, Golden Hearts, or duds. Whenever anything other than a dud lands, it is held for the duration of the feature. Spins are not capped, but the feature ends when no new Heart symbols land. Wins are then calculated based on the number of Hearts on the reels and the Heart Slot feature result. Any Golden Hearts gained during the Heart Slot feature are randomly allocated to Golden Heart meters.

Bonus Buy

Free spins can be purchased via the bonus buy for 75x the bet. This grants a random number of scatter symbols and runs with an RTP of 96.69%.

Hearts Highway: Slot Verdict

With the breakout success of 9 Masks of Fire and the flood of similar titles that followed, most players already know this style of scatter-driven instant prize win slot. Even so, quality varies a lot within the sub-genre, and Hearts Highway manages to push into the higher tier. It’s not the final word on the format, but it’s a strong entry. The sci-fi backdrop helps elevate what might otherwise have been a fairly standard classic slot setup, and the music is spot on. It certainly doesn’t feel like you’re stuck with something painfully dated.

The feature refinements make a difference as well. The Slot Machine symbols’ “reels within reels” moment adds extra tension when they show up, and they were reportedly inspired by a Push Gaming trip to Las Vegas—which tracks. If there’s one thing Vegas has in abundance, it’s slot machines; they’re waiting at the airport the moment you arrive and they never really stop. Slot Machine symbols may not appear constantly in Hearts Highway, but they’re a smart addition and can help unlock a higher prize value from the list. The Golden Heart collection mechanic in free spins can also pay off. The ideal outcome is filling all 3 meters with Golden Hearts so the middle three reels end up covered in locked Red Heart symbols. With nine Red Hearts paying 1,000x, landing just one more Red Heart would deliver Hearts Highway’s 10,000x the bet max win.

All told, Hearts Highway is an enjoyable, accessible take on this game type. The base game has plenty happening, the bonuses land often enough to feel rewarding, and there’s a lot here for casual players—though those who favour Push Gaming’s more “toothier” releases may find it less compelling.
