In the engaging world of puzzle gaming, players are tasked with the mission to "kill all the viruses with capsules of the same color." The game's board is filled with viruses in three vibrant colors: red, yellow, and blue. As a player, you'll have the power to manipulate each falling capsule, shifting it left or right and rotating it to align perfectly with viruses and any capsules already on the board. The thrill comes when four or more capsule halves or viruses of the same color connect in vertical or horizontal lines, causing them to vanish from the play area. Your primary goal is to clear levels by eliminating every virus from the field. However, the game ends if capsules pile up to the point of blocking the bottle's narrow neck.
Players have the flexibility to choose their starting difficulty whenever they begin a new game. You can select an initial level ranging from zero to twenty, which dictates the number of viruses you'll need to clear. Additionally, there are three game speed options that control the descent rate of the capsules within the bottle. Your score is determined exclusively by the viruses you eliminate, with no regard for the time you take or the capsules you use. After conquering the highest difficulty, players can continue to play and boost their scores, though the virus count stays constant. Bonus points are awarded for eliminating multiple viruses simultaneously, but no extra points are given for chain reactions, where the removal of one set triggers another. The game's speed also plays a role in scoring, with higher speeds leading to higher points.
