Dr Zappo, developed by Hacksaw Gaming, is a slot game featuring 5 reels and 4 rows. Players can win on up to 14 paylines, with a maximum potential win of 10,000x the bet. Wins can occur in all available game modes.
EyeBall symbols appear only on the fourth row. After the reels come to rest, any EyeBall symbols will fire in one of three possible directions: directly upward, diagonally to the left, or diagonally to the right. They are triggered sequentially, from left to right.

When an EyeBall fires, it transforms every paying symbol it passes into a Wild symbol. These symbols may remain as Wilds or instead display an Additive Multiplier value. Wild symbols substitute for all others on the paytable. The possible Multiplier values for Wild symbols are 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 15x, 20x, 25x, 50x, 100x, and 200x.

If an EyeBall hits an existing Wild symbol, that Wild receives a Multiplier value. When an EyeBall strikes a Wild symbol that already has a Multiplier, that value is increased by adding another Multiplier to it. The possible values for these added Multipliers are 1x, 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 15x, 20x, 25x, 50x, 100x, and 200x.
After activation, EyeBall symbols themselves turn into Wild symbols. When multiple Wilds with Multiplier values contribute to a winning line, those values are added together before being applied to the win.
Three Energy Fields appear on the left, top, and right edges of the reels. If activated, an EyeBall hitting one of these fields will bounce away at the same angle, continuing to convert all symbols along its new path into Wild symbols.

If an EyeBall hits an Energy Field head-on, it bounces back in the direction it came, granting additional Multiplier values to the Wild symbols it passes. If an EyeBall encounters another EyeBall symbol, it adds a Multiplier to it.
Land 3 FS scatter symbols simultaneously in the base game to trigger 10 free spins and enter the Eyeconic bonus round.

The Eyeconic feature retains the main game mechanics but gives a higher chance of EyeBall symbols appearing. You can gain extra free spins by landing more FS symbols at once during the bonus:
Trigger the No-Brainer bonus by landing 4 FS scatter symbols simultaneously in the base game. This awards 10 free spins.

This round uses the Eyeconic mechanics, with the additional twist that each triggered EyeBall symbol fires in two directions on each spin. Extra free spins are available during the bonus if more FS symbols land at once:
Unlock this Epic Bonus by landing 5 FS scatter symbols at once in the base game to receive 10 free spins.

This hidden round carries forward all features from No-Brainer and guarantees that at least one EyeBall symbol appears in every free spin. FS symbols cannot land during this bonus.
Note that FS symbols cannot land at the same time as EyeBall symbols.
Payouts in both the base game and feature rounds follow the same rules unless stated otherwise. Each bet is eligible for every available winning combination.
Wins are awarded when matching symbols appear on one of 14 defined paylines, across adjacent reels starting from the leftmost reel. The number of matching symbols needed for a win can be found in the paytable.
The return to player (RTP) details are displayed within the game.
