Paylines
30 fixed-max paylines (player-selectable down to 1)
Picture a teenage bedroom from a 1990s comic strip: striped pillows, a wardrobe stuffed with dresses, a rotary telephone the color of nail polish. That's the stage Genii built for All Heart, and it sets the mood before the first reel even moves. The grid is a tidy 5×3 with 30 fixed paylines, all left-to-right. Bets stretch from $0.01 up to $37.50, which keeps casual players and bigger spenders on the same machine.
The math is honest, if unspectacular. RTP sits at 96.2%, volatility lands in the medium bracket, and the ceiling tops out at 1,000x your stake. Is 1,000x modest by 2026 standards? Yes, frankly. But the trade-off is steadier hits and a Feature that pays often enough to keep the session warm.
Two scatters do the heavy lifting. The “03 FRIDAY” calendar triggers Free Spins: three scatters give 14 spins, four bumps it to 17, and five hands you 20. Every payline win during the round is doubled. Retriggers are possible. Your bet locks to whatever you spun in on, so plan accordingly.
The Heart scatter unlocks the Feature game, and this is where things get interesting. You get 3 spins. Any Feature symbol that lands sticks – classic hold-and-respin. An “Extra Spins” symbol resets the counter, which can push the round much further than expected. Nothing else pays during this mode. No wilds, no paylines, no other scatters. Just symbols accumulating, then revealing cash values at the end. It's a clean, focused mechanic. Refreshing, actually.
Symbol art leans into halftone-dot pop-art: roses bouquet up top (worth 500 coins for five), the rotary phone, a glowing heart, lipstick lips that double as the Wild. Card values get bubble-letter treatment with comic shading. The cabinet around the reels (bedside lamp, wardrobe, polka-dot wall) adds personality that most slots from this era skip entirely.
A couple of quirks worth noting. The Feature can't trigger while Free Spins are running, so you won't stack the two. And the visual style, charming as it is, will feel dated to anyone weaned on cinematic 3D slots. That's fair. But for a quick, light session with a satisfying respin mechanic, All Heart punches above its release year.
