In this engaging game, your mission is to eradicate all viruses using color-coordinated capsules. The game board hosts viruses in three vibrant colors: red, yellow, and blue. As a player, you'll skillfully maneuver each falling capsule, shifting it left or right and rotating it to align perfectly with viruses and existing capsules. The magic happens when you manage to line up four or more capsule segments or viruses of the same color either horizontally or vertically; they vanish from the board. Your primary goal? To clear all viruses from the field and conquer each level. Be wary, though—game over looms if capsules jam up the bottle's slender neck, blocking further play.

You have the power to tailor your challenge every time you start anew. Choose your initial difficulty level from zero to twenty, which sets the number of viruses you need to eliminate. Additionally, you can select from three speed settings that dictate the pace at which capsules descend into the bottle. Scoring in this game is straightforward and focused solely on virus elimination; neither the time you take to clear a level nor the capsules you use affect your score. Reach the top difficulty and continue playing to boost your score, though the virus count stays constant. Rack up bonus points by wiping out multiple viruses in one go, but remember, chain reactions won't add to your tally. And don't forget, playing at higher speeds can significantly increase your points, adding an extra layer of strategy to your gameplay.
