Dr Zappo

Dr Zappo is a paylines slot from Hacksaw Gaming, with volatility rated 3 out of 5 and a maximum win of 10,000x. Wild Eyeballs shoot upwards or diagonally, turning paying symbols in their path into Wilds. They can also bounce off Energy Fields, changing direction and affecting more symbols; hitting an existing Wild or Eyeball adds a multiplier to that Wild.

Three or more FS symbols trigger one of three bonus games, each awarding 10 free spins. Three FS bring Eyeconic, with a higher chance of Eyeballs; four trigger No-Brainer, where Eyeballs shoot in two directions; and five unlock It’s Electrifying, where at least one Eyeball lands on every free spin. Use the demo version to play for free and practice before playing for real money. Listed RTP settings are 96%, 94%, 92% and 86%.
