Spirit King

Spirit King slot review

Spirit King is a collection-driven slot from Relax Gaming, built around a slow-burn progression system rather than quick, immediate payouts. It plays on a 6-reel grid with 30 paylines, and the core hook is patience: the more you play, the closer you get to unlocking the game's full potential.

How the progression works

Spirit King is structured around collecting orbs during regular play — 60 of them are needed before the final stage of the game unlocks. Once that threshold is hit, the grid itself changes, expanding with an extra reel and building a multiplier that carries into the bonus round. Even after reaching that point, three scatters still need to land to actually trigger the main feature, so this is a genuinely multi-step build-up rather than a single easy target. A bonus buy is available at a comparatively low 60x the stake for players who'd rather skip the collection process and jump straight to the business end of the game.

Theme and feel

Spirit King leans into a mystical, spirit-guide aesthetic, matching its name with imagery built around growth and progression rather than a single flashy set piece. It's a game designed to reward sustained play, and the presentation reinforces that sense of steadily building toward something bigger.

What the RTP means

Spirit King runs a default RTP of 96.1%, a solid, slightly above-average figure that gives a fair long-run payback structure regardless of how quickly you reach the collection threshold.

Volatility and pacing

Rated high volatility, this is a game built for players who don't mind a longer run-up. The multi-step path to the bonus — orb collection, then the sixth reel and multiplier build, then landing three scatters — means the biggest moments are earned gradually rather than appearing out of nowhere.

Max win and stakes

The maximum win is capped at 5,000x the stake, a reasonable but not enormous ceiling given how much build-up is required to get there. Stakes run from 0.20 up to 200 per spin.

Verdict

Spirit King won't suit players after instant fireworks, but for anyone who enjoys a slot with a genuine sense of progression — where every spin nudges you a little closer to the good stuff — it's a worthwhile pick. The 60x bonus buy at least keeps the barrier to entry manageable for those who'd rather skip ahead.
