How to cite

Slot Summary

Players who give published return extra weight have a concrete reason to examine Secrets of Atlantis: its RTP is 97.07%. NetEnt pairs that figure with medium volatility and a 5x4, pay-both-ways format, but the distinguishing idea is the Highlight Feature. It can transform the middle reels into one colossal symbol area for a respin, while partially visible wilds nudge into full view. The underwater theme makes those sudden enlargements feel like discoveries rather than arbitrary grid changes.

How It Plays

The 5x4 field pays qualifying combinations in both directions across 40 lines. This makes symbols on either edge valid starting points instead of reserving that role for the left side.

Random highlighting on the middle reels can interrupt an ordinary result. When every central reel is selected, they combine for a Colossal Symbol Respin with a much larger symbol area.

Theme & Atmosphere

Atlantis and Mythology frame the game as an underwater discovery, with Animals and Fish occupying the surrounding Sea. The setting keeps the central transformation visually coherent.

Gems and Bubbles reinforce the idea of a submerged, preserved place. Rather than using the theme only as scenery, the expanding central area resembles a hidden object coming into view.

Features & Win Potential

Nudges complete any partially visible Wild Symbol by moving it into full view. Expanding Symbols and the Mega Symbol change occupied space, while Respins give those changes another result.

Pay Both Ways broadens where a qualifying line may begin, and stacked symbols increase repeated coverage. Together, those features make position and symbol size the important variables.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (Medium). The model is calibrated so the average return equals this slot's published RTP (97.07%), with wins capped at its top multiplier (3,200×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
