Lost Relics Slot Review: Cluster Pays, Hidden Chests and Wilds

Lost Relics is a 5×5 Cluster Pays slot where the important boundary is six matching symbols. Winning clusters can hide up to five random feature instances before the win is paid. Those features may add a coin prize, three Wilds or a Scatter, while three Scatters trigger ten Free Spins. In the bonus, winning clusters gradually uncover a hidden chest that can grant further spins, Sticky Wilds or another coin win.

Clusters, not lines

A cluster consists of symbols horizontally or vertically adjacent to the same symbol. Only clusters of six or more pay. Separate non-adjacent clusters of the same symbol count separately and pay separately. The exact record lists five reels, five rows, Cluster wins and bets from 0.20 to 400. Wilds substitute for all symbols except Scatters, can contribute to any cluster and can belong to more than one cluster, but Wilds pay only with other symbols.

When a main-game spin wins, up to five instances of three random features can activate after the reels stop and before wins are paid. The features may be hidden under symbols in winning clusters. This timing matters because the cluster remains the source of discovery while the reward is added before the round’s normal payout is complete.

Three hidden routes and Free Spins

Coin Win awards 3x to 30x bet from a symbol that remains part of the winning cluster. Extra Wild places three Wilds in positions outside the cluster and away from Scatters or Wilds; repeated activations can produce up to 15 Wilds. Extra Scatter awards one Scatter from a winning-cluster symbol, but no more than three Scatters can be awarded in total and the feature cannot activate after three have been reached.

Three Scatters activate ten Free Spins at the same bet and coin value. In Free Spins, a randomly hidden chest occupies spaces behind the reels. Winning clusters uncover spaces, and uncovered spaces carry to the next spin until the chest is fully revealed. A chest can grant Extra Free Spins, a Sticky Wild or a 1x to 30x Coin Win. After discovery, the spaces reset and a new chest is hidden; the first two chests are always small or medium, while later chest type is random.

Math and boundaries

The record reports 96.30% RTP, 6.5 volatility, hit frequency 20 and a maximum payout of 900x. Maximum-win probability is not supplied. The six-symbol threshold and chest rules are verified, but the packet does not state the exact chance of each random feature or chest size, so no frequency should be inferred.

Strengths and weak points

Strengths

The six-symbol adjacency rule is precise, and hidden features create a logical chain from a winning cluster to Wilds, Scatters, coins and Free Spins chests.

Weaknesses

Random feature and chest probabilities are absent, Extra Scatter has a strict three-symbol cap, and the 900x maximum provides no frequency context.

Our Editor’s View

Lost Relics has a strong causal chain: six adjacent symbols create a cluster, the cluster can conceal feature instances, and those features can add Wilds or Scatters that change later evaluations. Free Spins then turn winning clusters into progress toward a chest, with rewards that can extend, lock or pay. The explicit three-Scatter cap prevents Extra Scatter from being treated as unlimited, and the chest reset creates repeated discovery attempts without implying permanent accumulation. The principal limitation is probability data: random feature and chest outcomes are not quantified, and the 900x ceiling has no frequency. It suits players who prefer visible discovery through connected symbols.
