Amped Slot by Relax Gaming

Amped is a 5x4, 30-line release built around one of the most generous Free Spins menus Relax Gaming shipped that year - four entirely separate bonus modes, picked by which feature equalizer fills up during the base game. The reels sit on a black dance floor with magenta light trails curving out from behind the grid, and a stack of four LED display panels (red, orange, green, blue) runs down the right side, each one labeled with the bonus it tracks: BPM Boost Multiplier, Electro Expanding Wilds, Big Bass Sticky Wilds, and Remix Synced Reels.

The base game has its own respin layer. Land 2 Scatter Wilds anywhere on the reels and they lock in place while everything else respins, which is unusually generous - most slots want 3 scatters before they hand you anything. Symbols are loud and on-theme: red boomboxes with antennae and gold speaker cones, green cassette tapes, blue plug connectors, an orange floor speaker, and chunky neon-cut diamonds in red and green standing in for the low-pays. No royals, which is rare for a 2020 Relax title and helps the screen stay coherent.

The bonus picker is where the design choice gets interesting. Each of the four LED meters fills based on what you trigger free spins with, and the matching color decides your mode. BPM Boost runs a multiplier that climbs as the round progresses. Electro Expanding Wilds stretches any wild to fill its full reel. Big Bass Sticky Wilds locks wilds for the rest of the round. Remix uses Synced Reels so two or more reels spin identically, stacking matching symbols across the grid. Four genuinely different math models, not four cosmetic skins of the same one.

No buy bonus, no ante bet, no jackpot ladder. The single-spin ceiling caps around 450x, but the progressive multiplier mode is the route to the four-figure top end. Worth knowing before you pick a session: which bonus you land in matters more here than in most slots, because the variance shifts noticeably between sticky wilds and the BPM mode.
