Features Hearts Highway is a five-reel slot game by Push Gaming that combines a classic machine layout with a futuristic theme. The game uses 20 paylines and reports a medium-high volatility profile, with RTP figures that may vary by casino.
During base spins and free spins, four or more Heart symbols can trigger instant prizes, with awards ranging from 2x the bet to 10,000x. A Slot Machine symbol on reel 1 or reel 5 can add Hearts to the grid, while matching Slot Machine symbols on both outer reels activate the Heart Slot feature for a larger Heart award.
The free spins round starts with three or more Scatter symbols. In this mode, Golden Hearts unlock a reel meter, and when three are collected the reel below is filled with Hearts for the rest of the feature, with an extra free spin added. The demo version is available to play for free, giving players a chance to practice before playing for real money.
