Strata by Arcan Game Slot Overview
Strata by Arcan Game turns a prehistoric excavation into a warmly lit, cartoon-styled adventure. Its amber accents frame Cluster Pays and tumbles shared with Sweet Fiesta, but here winning clusters break fossils beneath the symbols to uncover bones.
The Skeleton Multiplier grows with collected bones, boosting subsequent tumbles and carrying over throughout free spins. Evolving dinosaur skeletons add further depth, while the maximum win reaches 25,000x the bet. Explore the excavation for yourself with the free demo on BonusTiime, without an account or deposit.

Strata Slot Features

Cluster Pays, Tumbles, Fossils, Bones, Free Spins, and the Bonus Buy menu define Strata’s excavation loop, while the skeleton evolves across the bonus and keeps each round moving through layered progress.
Cluster Pays
Strata pays on clusters instead of lines, so the position of a win matters less than the shape of the group. A cluster needs 5 or more matching symbols touching horizontally or vertically, and all wins on a spin add together. Amber (Wild) joins any cluster it touches.
Tumbles
Every winning cluster disappears, then new symbols fall into the empty spaces. That can create several wins from one spin, which keeps the pace moving and adds extra value when clusters keep forming. Fossils stay in place, so the board keeps changing around them.
Fossils and Bones
Fossils sit under some cells and act like rock layers with 2 hits or 1 hit. Winning clusters break them open, and each broken Fossil sends a Bone to the skeleton. Every Bone raises the Skeleton Multiplier, but it only affects wins from the next tumble onwards.
Skeleton Multiplier
The skeleton starts at x1 and multiplies every cluster win. While it remains a Raptor, each Bone adds +1, and the multiplier caps at x100. In the base game, the dig site and skeleton reset on every spin, so each round starts fresh.
Cave-In
If a base game spin pays nothing, a Fossil is on the grid, and the bonus has not triggered, the quarry wall can collapse. When that happens, 1 or 2 reels drop again with new symbols, and the game evaluates the spin once more. That gives the base game an extra recovery route.
Free Spins
Land Expedition Seals to trigger the bonus, and the dig site plus skeleton stay active throughout. 3 seals open Excavation with 10 free spins, 4 seals open Deep Dig with 12, and 5 or more open Deep Dig with 15.
- Excavation: 10 free spins with the site and skeleton preserved.
- Deep Dig: 12 free spins, or 15 with 5 or more seals.
- Deep Dig start: the skeleton begins as a Triceratops at x5.
- Retriggers: 3 or more seals add 5 free spins, 2 seals add 2.
Bonus Buy
This feature lets players buy activation chances or jump straight into bonus modes.
- Metal Detector: x1.25 the bet per spin – the bonus opens about 1 spin in 160 instead of 1 in 230.
- Survey Drill: x15 the bet – one spin with 4 Fossils.
- Excavation: x100 the bet – starts 10 free spins.
- Mystery Crate: x150 the bet – Excavation 75.4%, Deep Dig 24.6%.
- Deep Dig: x300 the bet – starts 12 free spins.

Strata Slot Review
Strata builds its identity through a fossil-digging theme, warm amber lighting, and a board that looks like an archaeological worksite rather than a standard reel set. The Cluster Pays format fits the underground setting well, while the fossil layers and skeleton artwork give the game a clear practical purpose.
The gameplay stands out because wins do more than pay out. Tumbles keep the board active, Fossils add another layer to every hit, and the evolving skeleton multiplier gives each tumble extra weight. The Medium-High volatility and 25,000x ceiling create proper upside, but the buy menu can make the structure feel a bit crowded.
Strata suits players who want a bonus driven slot with progression rather than a simple cluster spinner. The free spins ladder, retriggers, and skeleton stages give the game more texture than many rivals in this format. It will appeal most to patient players and bonus hunters who value mechanics over polish.
Strata Slot FAQ
How Does Strata Trigger The Bonus?
Strata triggers its bonus with Expedition Seals. Three seals open Excavation with 10 free spins, four seals open Deep Dig with 12, and five or more seals open Deep Dig with 15. Seals pay nothing by themselves, but they start the bonus round when enough land together.
What Does The Bonus Buy Menu Offer?
The Bonus Buy menu includes Metal Detector for x1.25 the bet, Survey Drill for x15 the bet, Excavation for x100 the bet, Mystery Crate for x150 the bet, and Deep Dig for x300 the bet. Each option either boosts access to bonuses or starts a chosen mode directly.
What Is The Max Win In Strata?
Strata has a max win of 25,000x the bet. The rules state that this cap applies across the main modes, with Survey Drill limited to 2,000x. Once the maximum win is reached, the round ends immediately and any remaining features are forfeited.
Can You Play Strata For Free?
Yes, the free demo is available on BonusTiime. You can play it without a deposit or account, which makes it easy to test the 6×5 cluster format, the bonus buy menu, and the fossil based mechanics before staking real money on Stake.com.
How Does The Skeleton Multiplier Work?
The Skeleton Multiplier starts at x1 and rises when Bones fly to the skeleton from broken Fossils. In the base game, every Bone adds +1 while the skeleton is a Raptor. In free spins, the skeleton can evolve, which changes how each Bone adds to the multiplier.
