Energoonz doesn't come with a traditional payline structure - payouts are made every time you find 3 or more symbols in a line, either vertically or horizontally. The setup is 5 reel, 5 row and pretty spectacular it looks too. The reels are crammed full of an assortment of brightly coloured, cartoon style aliens as well as thunderbolts and flames. They're superbly done, set against the dark space backdrop. The action plays out to a hypnotic, ambient soundtrack that matches the theme nicely.
Energoonz is much more than just a good looker though - there are some decent features on offer too. You'll notice a large electro machine to the right of the reels. After every successful spin, the winning symbols will be zapped by the machine and disappear, either being replaced by another symbol or left blank. The middle zapped symbol is always a wild boosting your chances of finding another winner. The cascades mean that you can enjoy multiple payouts from a single spin.
After every winning spin you'll be awarded a multiplier. If the cascading symbols create another winning line the multiplier will go up by one, up to a maximum of 5x. The displaced symbols may reveal the letter B.O.N.U.S vertically on each reel. If you manage to reveal B.O.N.U.S in full you'll trigger the feature.
You'll be awarded an initial 10 free spins on a new set of reels featuring 10 new aliens but minus the cascading symbols. Hitting 5 aliens will give you a prize. Land five of the energy coil symbol and you can trigger plenty more free spins (up to 20). If you manage to clear all of the symbols from the reels in the base game, a 1,000x bonus awaits.
The overall variance is on the low side, so expect plenty of smaller wins rather than anything too stellar. You should get plenty of play for your money though, making it an ideal choice for low rollers and microstakes player.
Play 'N Go have fused elements from arcade games as well as slots to create an entertaining overall package. Energoonz looks and sounds a treat - the visuals and backing track are excellent. The actions comes thick and fast too, keeping even the most ardent action junkies happy.
Relatively simple it may be, but it's no less enjoyable to play for that. If you like alien/spaced themed slots, NetEnt’s Aliens is graphically brilliant but I prefer Invaders from the Planet Moolah by WMS which also has cascading wins and is higher variance.
