Dr Zappo
HacksawDescription
Built around Eyeball symbols that fire across the screen and convert paying symbols into Wilds, this Hacksaw slot has a maximum win of 10000 times the stake. Dr Zappo adds three tiers of free spins triggered by 3, 4 or 5 FS symbols.
How to play
A round begins with the stake set and the reels spun. Wild and Scatter symbols can land during the base game, and Autoplay can repeat spins automatically. When an Eyeball appears, it fires in one of three directions and changes the paying symbols in its path. Collecting FS symbols opens one of the bonus games. The slot can be tried in a free demo and plays on phones and tablets as well as desktop. For background on how lines and ways work, see paylines and ways.
Theme and symbols
The symbol set is short: EyeBall, FS and Wild. The Eyeball is the central piece, acting as the source of the transformations, while the FS symbol is the scatter that leads into the bonus rounds.
Features
Wild Eyeball symbols: each Eyeball shoots straight up, diagonally left or diagonally right, turning the paying symbols it passes into Wilds.
Energy Fields: when an Eyeball shoots into one, it bounces off in another direction and transforms more symbols along the new path.
Multiplier on Wilds: if an Eyeball hits an existing Wild or Eyeball, a multiplier value is added to that Wild.
Eyeconic Bonus Game: 3 FS symbols trigger 10 free spins with an increased chance of landing Eyeballs.
No-Brainer Bonus Game: 4 FS symbols trigger 10 free spins in which Eyeballs shoot in two different directions.
Hidden Epic Bonus - It's Electrifying: 5 FS symbols trigger 10 free spins where at least one Eyeball lands on every spin.
The top prize is explained in the guide to max win. More titles are collected among all Hacksaw games, and the wider slots lobby has other options.
