A mad doctor and Mr. Brain fire Wild Eyeballs that bounce off Energy Fields and build multipliers in this 14-line slot with a 10,000x max win.

Dr Zappo is a mad genius with a new experiment. Together with his partner Mr. Brain, he has created a beast that can flatten a whole city in minutes. Hacksaw Gaming’s five-reel game pays across 14 paylines and offers a max win of 10,000x the bet.

Gameplay

The main feature is the Wild Eyeball symbol. When it lands, it shoots in one of three directions: straight up, diagonally to the left or diagonally to the right. Every paying symbol in its path turns into a Wild. Energy Fields sit on the grid as well. When a shot hits one, it bounces off and carries on in a new direction, turning more symbols into Wilds on the way. If a shot hits a Wild or another Eyeball that is already on the grid, that Wild gets a multiplier.

Bonus games

Three FS symbols trigger Eyeconic, which awards 10 free spins with a higher chance of landing Eyeball symbols. Four FS symbols trigger No-Brainer, also with 10 free spins, where Eyeballs shoot in two different directions instead of one. Five FS symbols open the Hidden Epic Bonus, It’s Electrifying. It awards 10 free spins, and at least one Eyeball lands on every spin.

RTP, volatility and max win

The default RTP is 96.31%, with 94.36%, 92.31% and 86.22% versions also available. Hacksaw rates the volatility 3 out of 5 (Medium), and the hit frequency is 45%. The max win is 10,000x the bet, and bets range from 0.10 to 100.
