Energoonz

Energoonz is a sci-fi grid slot from Play'n GO, released in 2013 and built on a 5x5 matrix. Wins are formed by matching three or more identical symbols horizontally or vertically, with winning clusters removed from the grid before new symbols drop into place. This cascade system can create consecutive wins in a single round.

The game includes a Plasma Ball Wild, which substitutes for other symbols. Each cascade increases a win multiplier, and clearing the full grid can trigger a large payout. In the demo version, players can play for free and study the mechanics before playing for real money.

A bonus round is activated when columns reveal the word BONUS. In this feature, wins come from five or more matching symbols anywhere on the grid, multiplied by the bonus multiplier. Collecting five or more energy container symbols can award up to 20 additional free-spin rounds, making the game’s feature structure clear for players who want to practice before playing for real money.
