Artifacts Slot Review: Peter & Sons Layer Multipliers Onto A Cascading Excavation

Artifacts is a 5-reel, 243-ways release from Peter & Sons built around cascading wins and a multi-layered multiplier system that gives the game a distinctly momentum-driven feel rather than a standard tumble-and-repeat structure. Set among buried relics and forgotten ruins, it's an archaeology-themed slot that leans on its mechanics rather than elaborate storytelling to hold attention.

The base game works through a familiar cascade loop: winning symbols clear from the grid and new ones drop in to potentially chain further wins. What sets Artifacts apart is how reel multipliers interact with that process — each reel involved in a winning cascade contributes its own multiplier value, and when several reels combine within the same cascade sequence, those multipliers stack together and apply to the total win. The catch is that multipliers reset at the end of every base-game spin, so most of the escalation happens within a single cascade chain rather than building gradually across an entire session.

Randomly triggered feature boxes beneath the reels add an extra layer of unpredictability, capable of boosting a single reel, the whole grid, or adding flat increases to existing multipliers — and when they land during an active cascade chain, the payout can escalate quickly. Golden-marked symbols provide another route to bigger wins, converting into wilds on the following spin if they were part of a winning combination.

Free spins are triggered by landing three or more scatters, opening with six spins and adding two more per extra scatter on the trigger. Crucially, reel multipliers stop resetting between spins once free spins begin, which is where the game's real ceiling opens up — early multiplier momentum combined with cooperative feature boxes can snowball into substantial totals.

RTP sits at 96.26%, a solid figure above the typical market average, paired with high volatility that fits the multiplier-stacking design. Max win potential reaches a hefty 20,000x the stake, positioning Artifacts as a volatility-first title for players chasing big multiplier moments rather than steady, frequent returns. Stakes run from 20p/c up to $/€50 per spin, and optional paid entries — including a golden bet and tiered bonus buys — offer more direct routes into the persistent-multiplier free spins for players who'd rather skip the wait.

The reset-every-spin rule on base-game multipliers is worth keeping in mind when sizing up sessions: it means the base game and the free spins effectively play like two different games in terms of ceiling potential, with the persistent-multiplier bonus doing almost all of the heavy lifting toward that 20,000x figure. Players chasing the biggest possible outcomes should treat scatter triggers, or a bonus buy, as the real target rather than expecting base-game cascades alone to build toward anything dramatic.
