About this world

Sunken Atlas

Sunken Atlas is a deep dive, and deep dives take breath. Fifteen lines carry the stake, the reels are weighted sparsely, and the pay table saves its weight for the Coral Owl and the Pearl Compass, so quiet stretches are part of the expedition. The reward for persistence is the Surfacing Ladder. Three Barnacle Keys unlock twelve free spins that begin at double and rise to five times by the fifth spin, staying there to the end. Four keys bring eighteen spins, five bring thirty.

Surfacing Ladder. The free round opens at double for two spins, triples for the next two, then pays five times on every remaining spin with no reset.

The honest part

Coins only, always

Everything here is played with free virtual coins. There is no real-money gambling, nothing you win has real-world value, and there are no in-app purchases. Results come from a random number generator; past spins never affect the next one.

Measured by running this page's own engine for 5,000,000 spins: coin RTP 94.1%, hit frequency 29.6%, free spins about once in 179 spins, a win of 10x your stake or more about once in 103 spins. Coin figures only — no money is staked or returned.

How to play

Sunken Atlas in three steps

1

Log in and pick a stake for the fifteen lines.

2

Spin and search for Barnacle Keys. They pay anywhere, and wilds cannot stand in for them.

3

Three keys open twelve free spins, four open eighteen, five open thirty, on the Surfacing Ladder: x2, x2, x3, x3 and x5 from then on.

Who it suits

Treasure-seekers who prefer one long dive to lots of little paddles.

What to expect

Quiet stretches are frequent, and much of the value lives in the Coral Owl, the Pearl Compass and the free round. A long round matters, because every spin after the fourth pays five times.

Questions

About Sunken Atlas

On the fifth free spin. From there it stays at five times to the end of the round, including any added spins.

Yes. Three or more Barnacle Keys inside the round add more spins at the multiplier you have already reached.

Probably not. It is one of the most volatile worlds here; a gentler world such as Gilded Glacier is easier to learn on.
