Lost Relics is NetEnt’s 2019 cluster pays slot with an archaeological adventure theme — a game that distinguishes itself within the cluster format through its mid-spin surprise mechanic and a free spins structure that can extend itself through treasure chest finds. It’s thoughtfully designed and rewards players who are willing to read what the bonus reveals before deciding what to do with it.

Wins form through clusters of five or more matching symbols on the grid rather than fixed paylines. Bets run from $0.20 to $400 per spin — a notably wide range for a cluster pays title. The adventure theme takes place in an excavation site, with the reels framed by dig equipment, ancient maps, and artefacts surfacing from beneath the grid.

The Dig Site bonus triggers randomly during the base game, awarding instant cash prizes mid-spin without requiring a scatter or cluster trigger — a useful secondary income that keeps the base game from feeling entirely passive. Free Spins are the main feature: once triggered, treasure chest symbols appear on the reels. Opening chests reveals either instant cash prizes or additional free games, meaning a productive chest sequence can extend the bonus round considerably beyond its initial allocation.

The RTP is 96.3% with high volatility — the cluster format means wins cluster around certain spin sequences rather than arriving steadily. The max win potential is 5,000x your stake, driven by the combination of cluster cascades and chest reveals during a well-extended free spins round.

Lost Relics suits players who enjoy cluster pays slots with a bonus that has self-extending potential. The Dig Site random prizes add base game texture, and the treasure chest free spins structure gives the feature a satisfying unpredictability that pure spin-count bonuses lack.
