If you like games that offer the simple gameplay often found in live casino slots, you’ve come to the right place here. Secrets of Atlantis is not overloaded with features. There are a couple of extras here that can get these waters to bubble away nicely.

Colossal Symbol Re-spins

On each spin, any of reels 2, 3, and 4 can be highlighted in a mysterious glow. What you’re hoping to see is all 3 middle reels highlighted. When this happens, it triggers the Colossal Symbol Re-spin Feature.

The highlighted reels merge to create a single reel and a re-spin is awarded. The reel on the re-spin is made up solely of colossal symbols which are 3 symbols wide and 4 symbols high. These colossal symbols can land partially or in full on the middle 3 reels.

The highlights are active on the re-spin too. If the reel with the colossal symbol is highlighted, you’ll receive another re-spin.

Land matching symbols alongside the colossal symbol and the action starts to motor.

Nudging Wild

The mermaid is the game’s wild symbol. As usual, this substitutes for all the standard symbols when it makes up part of a winning combination.

The wilds here also have additional properties. If only part of a mermaid wild lands on a reel, it nudges up or down until the whole of that reel turns wild.

The mermaid wild can appear as a colossal symbol during the re-spins feature. If a wild partially fills the colossal reel, it nudges up or down until all of it becomes wild. This can create some spectacular combinations.
