In the thrilling puzzle game, your mission is to eradicate viruses using color-coordinated capsules. The game board hosts viruses in three vibrant colors: red, yellow, and blue. As a player, you skillfully maneuver each descending capsule, shifting it horizontally and rotating it to align perfectly with the viruses and any pre-existing capsules. Victory comes when you manage to connect four or more segments of capsules or viruses of the same hue, either vertically or horizontally, causing them to vanish from the board. The ultimate goal? To clear all viruses and conquer each level. Be warned, though; the game ends if capsules pile up to the point where they block the bottle's slender neck.

Before diving into the action, you have the freedom to set your starting difficulty, choosing a level from zero to twenty that dictates the initial virus count. Additionally, you can tweak the game speed to one of three settings, which affects how quickly capsules descend into the bottle. Your score hinges exclusively on your virus elimination prowess, not on the speed of completion or the capsules you expend. If you triumph over the toughest level, the challenge doesn't end there—you can keep playing to rack up a higher score, though the virus count stays constant. Scoring gets a boost when you wipe out multiple viruses in one go, but initiating chain reactions won't earn you extra points. Remember, the faster the game speed, the more points you'll score, adding an extra layer of strategy to your gameplay.
