How the Game Plays

Aquanauts by Alchemy Gaming plunges players into the silent, dark depths of the ocean on a 5x5 grid with 3,125 ways to win. The aesthetic is clean and industrial, focusing on high-tech submarines and a team of professional divers. Wins are achieved by landing matching symbols on adjacent reels from left to right. This slot utilizes the Rolling Reels™ mechanic, where winning symbols vanish to let new ones fall into place, allowing for consecutive wins on a single spin. Each successful roll in the base game also increases a win multiplier by +1, which resets only when the winning sequence ends.

Free Spins Explained

Landing three or more Scatter symbols triggers the Free Spins feature, beginning with 8 spins plus 2 additional spins for every scatter beyond the third. Before the round starts, a Bonus Wheel spins to award specific upgrades, such as extra spins, higher multiplier increments (up to +3 per roll), or the removal of low-paying symbols from the Echo Roll™ pool. During this round, the win multiplier is persistent and does not reset between spins, allowing it to build throughout the entire feature.

Echo Roll™ and Upsizer™ Features

The trademarked Echo Roll™ feature can trigger randomly after any winning combination. It fills the empty positions left by a win with a single type of matching symbol—guaranteeing a follow-up win. This feature can generate low, high, or even wild symbols. Additionally, the Upsizer™ feature provides a unique layer of control; once the free spins are triggered and the initial wheel has spun, players may choose to pay a calculated cost to upgrade their remaining modifiers to higher levels.
