The Alien World of Energoonz
Energoonz transports players into a dark, cosmic void filled with colourful, cute alien creatures known as “goonz.” The sci‑fi grid slot features simple yet bold animations, coastal‑star backdrops, and a lively soundscape that reacts to every spin. The visual design blends playful sci‑fi elements with an immersive, otherworldly atmosphere that keeps players engaged.
Free Spins and Bonus Features in Energoonz
Free Spins (Bonus Game)
The Free Spins round activates when a column marked “Bonus” is cleared of all symbols, or when the word “BONUS” is revealed in one or more columns. On average, it takes 88 spins to trigger. During this feature, all wins are multiplied by a multiplier that depends on how many Bonus columns were fully removed. A different set of symbols appears, with new alien symbols offering payouts up to 1,000x your bet. Players can retrigger up to 20 additional Bonus Rounds by landing five or more Bonus symbols (the Energy container) or via 5‑10 combinations of the bonus game.
Scatter Symbol
The Scatter symbol is represented by an Energy container. Landing five or more Scatters anywhere on the grid triggers the retrigger mechanism during Free Spins. Outside the bonus game, the Scatter does not award direct payouts but plays a key role in extending the feature.
How to Play Energoonz
Set your bet between 0.20 and 50 using the controls, then spin the 5x5 grid. Wins are formed by landing five or more matching symbols anywhere on the grid (cluster pays). Winning clusters are removed, and new symbols fall into place from above. The Win Multiplier increases with every subsequent drop, boosting your winnings in a chain. The Plasma Ball Wild symbol substitutes for any other symbol to help complete winning clusters. You can adjust your wager at any time and use autoplay for uninterrupted action.
