How the Game Plays

Infectus, developed by Spinmatic, invites players into a vibrant microscopic world where colorful bacteria and viruses act as the primary symbols. The game utilizes a 5x3 grid with 10 fixed paylines that feature a "Win Both Ways" mechanic, meaning combinations pay out from both the leftmost and rightmost reels. This design choice effectively doubles the number of opportunities to strike a winning combination on every spin. The visual aesthetic is cartoonish and cheerful, featuring a cast of bubbly microbe characters that bring a lighthearted tone to the scientific theme.

Expanding Sticky Wilds Explained

The standout feature of this slot is the blue microbe Wild symbol, which appears exclusively on the second, third, and fourth reels. When one of these symbols lands, it expands to cover the entire reel. Once expanded, the Wild becomes sticky and triggers a free respin of the remaining reels. If another Wild appears during the respin, it also expands and locks in place, awarding an additional respin. This can occur up to three times consecutively, potentially filling the three middle reels with Wilds for significant payout potential. Because the game lacks a traditional scatter-triggered bonus round, this respin mechanic is the primary engine for generating larger wins.
