Artifacts is Peter & Sons operating at their creative best. The artifact collection mechanic gives every base game spin a secondary purpose — building toward a free spins configuration that is defined by what you collected, rather than a uniform trigger reward. At 20,000x maximum win it punches well above the standard 243-ways ceiling, and the 96.26% RTP ensures the volatility is priced fairly. The visual production is characteristically distinctive for Peter & Sons — this is not a generic archaeology reskin, it's a fully realised world. One of the more interesting high-variance releases we've reviewed this year.
Artifacts drops players into a dusty excavation site where five reels and 243 ways to win frame an artifact collection mechanic that runs through every spin. Peter & Sons built this slot around a simple but effective idea — ancient relics surface on the reels during the base game, each one adding to a collection that defines the multiplier configuration entering the free spins round. The more complete the collection, the more powerful the bonus.
Artifacts — base game.
Peter & Sons' visual fingerprint is immediately recognisable here — bold linework, a richly illustrated reel set populated with hand-drawn archaeological symbols, and an animated excavation site backdrop that reacts to wins. The 243-ways format means symbol combinations form across any adjacent reel positions rather than fixed lines, keeping the win rate consistent enough to sustain base game engagement while the collection builds.

Distinct artifact symbols appear on the reels during the base game. Each unique artifact collected is registered in a display above the reel set — collecting a complete set of any artifact type upgrades the multiplier tier associated with that artifact for the free spins round. Partial collections still contribute lower-tier multipliers, meaning every base game session carries value into the bonus regardless of how complete the collection is at the point of triggering.
Landing 3 or more scatter symbols triggers the free spins round. The multiplier values accumulated through artifact collection are applied to wins during free spins — and if multiple artifacts of the same type land during the bonus, their multipliers stack. A well-collected set entering a free spins trigger can produce multiplier stacks that compound rapidly toward the 20,000x ceiling, particularly when high-value symbols align across all 243 ways simultaneously.
Wild symbols substitute for all standard reel symbols to complete 243-ways combinations. Wilds interact with the artifact multiplier system — a wild completing a high-value combination during free spins with an active artifact multiplier produces the same elevated payout as a natural symbol landing in that position. Multiple wilds contributing to the same combination on different reels benefit from the full multiplier value applied once to the total combination win.
The 243-ways format means any symbol on reel 1 can connect with any matching symbol on reels 2, 3, 4, and 5 — no fixed paylines required. This creates a naturally higher base game win frequency than comparable 10 or 20-payline formats, which is important for the artifact collection mechanic: more wins mean more artifact appearances, and more artifact appearances mean a more complete collection entering the bonus. The $0.20 minimum bet covers all 243 ways automatically.
Most 243-ways slots are functionally identical between base game and bonus — the only variable is how many free spins you received and whether a fixed multiplier applies. Artifacts disrupts this by making the path to free spins matter. Two players triggering the bonus at the same session length can enter with very different multiplier configurations depending on how their artifact collection developed. One player who landed a complete set of the highest-value artifact type enters free spins with a significantly more powerful multiplier than a player who only partially completed collections.
This creates genuine engagement with the base game beyond just waiting for scatter triggers. Watching a collection near completion on a high-value artifact type — and seeing whether the final piece lands before the scatters — is a layer of tension that keeps the base game from feeling like a waiting room. It's a design approach we associate more with high volatility titles from boutique developers like Peter & Sons than from the larger studios.
The 20,000x ceiling is extraordinary for a 243-ways format — most comparable slots cap at 5,000x to 10,000x. Reaching it requires a full collection of multiple artifact types entering free spins, followed by multiplier stacks aligning with maximum-value 243-ways combinations. It's a demanding path, but the 96.26% RTP confirms the payout model is mathematically sound. Check our slot RTP list to see how it compares across the market.
Artifacts — bonus round.
Artifacts earns an 8.0/10 from SlotArk — rated Excellent. The artifact collection mechanic genuinely differentiates the base game experience, and the 20,000x ceiling is remarkable for a 243-ways slot. The 96.26% RTP prices the high volatility fairly. Best suited to experienced players who enjoy a session with clear forward momentum and a bonus round that reflects the quality of base game play.
Artifact symbols land on the reels during the base game and are added to a collection tracker above the grid. Each unique artifact type has an associated multiplier tier — completing a full set of any type upgrades that tier's multiplier for the next free spins trigger. Partial collections still contribute lower multiplier values. The collection resets after each free spins round.
The maximum win is 20,000x your total stake. Reaching it requires completing multiple high-value artifact collections before triggering free spins, then landing maximum-value 243-ways combinations with stacked artifact multipliers active during the bonus round.
Artifacts has an RTP of 96.26% — solid for a high volatility slot. Some casinos may operate reduced RTP configurations; always check the slot RTP list or the game information panel before playing.
