Energoonz is a sci-fi grid slot from Play'n GO, released in November 2013. The game uses a 5x5 matrix where wins are formed by matching three or more identical symbols horizontally or vertically. Winning clusters are removed from the grid, and new symbols drop into place to create cascade sequences.
The base game includes a Plasma Ball Wild, which substitutes for other symbols to help complete combinations. Each cascade increases a win multiplier, and clearing the entire grid in one sequence awards a payout of 1,000 times the total bet. The game is presented with alien-themed visuals and futuristic artwork.
The bonus round is triggered by clearing a full column marked BONUS. In the bonus game, wins are made by matching five or more identical symbols anywhere on the grid, with all wins multiplied by the bonus multiplier. A separate symbol set can also award up to 20 extra free spins by collecting five or more energy container symbols. A demo version is available to play for free and practice before playing for real money.
