Dr. Mad

Kagaming's Dr. Mad is a video slot that features a layout consisting of 5 reels and 3 rows, along with 10 fixed paylines. Set in a mad scientist's laboratory, the game showcases vibrant flasks, bubbling potions, unusual gadgets, and the Doctor himself amidst futuristic lab equipment. Wild symbols can appear on reels 2, 3, or 4; when one is present, it expands to fill the entire reel and activates a respin, with the expanded wild reel remaining locked. The chain of respins continues as long as more wilds land on the middle reels. Wins are awarded in both directions, from left to right and right to left, on the paylines. Unlike many other games, Dr. Mad does not include a traditional free spins round triggered by scatters, nor does it offer bonus rounds or options to buy bonuses. The main attractions of the game are the expanding wild reels and the series of respins, which enhance the excitement of the base game’s straightforward design. The overall style is lively and chaotic, focusing on wild growth and buildup rather than intricate bonus features.
