Energoonz — slot review

Energoonz is the ancestor of Play'n GO's entire cartoon-alien line, arriving long before Reactoonz. One-eyed creatures group up in clusters of three or more on a 5x5 grid, wins evaporate and new symbols drop in from above, the classic cascade that was a fresh idea back in 2013. Destroyed goonz fill an energy meter: collect enough and you earn free rounds with a bonus multiplier, while the word BONUS spelled out in a column brings extra perks. Today the slot looks charmingly retro, but it remains historically important and pleasantly playable. A good pick for getting acquainted with the roots of the cascade genre.
