Lost Relics™ by NetEnt is a 5-reel, 5-row video slot built around Cluster Pays™ mechanics. The game uses archaeology-inspired symbols, with low-paying card suits and higher-value icons such as a Spartan helmet, dagger, and sheath. Its listed RTP is 96.3%, with medium-high volatility and bet sizes from 0.2 to 400.
The slot includes several features tied to winning clusters: Coin Win awards 3 to 30 times the bet to one symbol in a cluster, Extra Wild adds three Wild symbols to open positions, and Extra Scatter can place an additional Scatter symbol within a win. Chests hidden behind the reels may reveal Extra Free Spins, Sticky Wilds, or Coin Wins. Three Scatter symbols in the main game trigger 10 Free Spins.
During Free Spins, a chest remains hidden behind the reels and is uncovered as winning clusters appear, with progress carrying over between spins until the chest is found. The demo version is available to play for free, allowing players to review the cluster-based mechanics and bonus features before playing for real money.
