# Dr. Virus The game features multiple levels, each with its own unique challenges and objectives. As players progress through the game, they encounter increasingly difficult puzzles that require careful planning and critical thinking. The puzzles are designed to keep players at the edge of their seats, constantly engaged and eager to solve the next challenge. To eliminate the viruses, players must create chains by matching three or more viruses of the same color. The chains can be formed horizontally or vertically, and when triggered, they clear the matching viruses from the board, earning points and creating space for new viruses to appear. Players must think ahead and consider the placement of each virus to maximize their chain reactions and achieve higher scores.
