Immortal 5 Slot by Relax Gaming

The reels sit on a violet-lit cyberpunk skyline at sunset - mirrored glass towers reflecting orange-pink sky, neon billboards, distant bridges. Five hero portraits fill the high pays: a green-clad woman with long black hair, a white-haired man in cyan, a star-emblem fighter in red, a blue-haired elf-styled rookie, and a fifth team member that rotates depending on your spin. Lows are angular gem icons in red, blue, green and purple, all rendered in glossy comic-book inking.

Wins land left-to-right across 15 fixed paylines on a 5x5 grid. The signature feature is the Immortal 5 random trigger - any base spin can spawn up to five Hero Wilds across the reels for that round. Each Hero corresponds to a different Wild behaviour (some expand, some carry x20 or x50 multipliers, the splash teases values x20 and x50 beside two of them). The Hero Bet button on the left of the grid acts as an ante toggle, increasing your stake to 1.5x for significantly higher trigger frequency on the random feature and bonuses. Worth pulling for almost any session - the base game without it is noticeably stingy.

Three or more Scatters trigger Free Spins. The bonus runs across multiple variants (the splash shows Bonus, Gold Bonus, Silver Bonus as distinct tiers) with persistent Hero Wilds carrying over and a Pick & Click holographic prize game tucked into the round structure. The win-level transitions (Big, Mega, Super, Epic) play out with full comic-book splash effects. Cap is 10,000x bet.

Buy Bonus is dual-tier and one of the options is unusual: Buy Free Spins runs at 100x your stake, and Buy Max Win runs at 500x for a direct shot at the 10,000x cap in a single round. Both options sit at 96.5% RTP. The 500x Max Win Buy is rare in the studio's catalogue - most titles cap their Buy Bonus tiers at the standard Free Spins entry. So if you want the all-or-nothing run at the ceiling, this is one of the few Relax titles that offers it directly. Trade-off: 500x is a serious commitment and the math is built around lots of zeros to balance the rare big hit.
