In the engaging world of this puzzle game, your mission is to eradicate all viruses using color-coordinated capsules. The game board features viruses in three distinct 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 the viruses and any capsules already in place. The key to success lies in creating alignments of four or more capsule segments or viruses of the same color, either horizontally or vertically, which will then be cleared from the board. Your ultimate goal is to progress through levels by completely eliminating all viruses present on the playing field. Be cautious, though; the game ends if capsules stack up to the point where they block the bottle's narrow neck.
You have the flexibility to choose your starting difficulty each time you begin a new game. This difficulty level, ranging from zero to twenty, dictates the number of viruses you need to clear. Additionally, you can select from three different game speed settings, which affect the descent rate of the capsules within the bottle. Your score is determined exclusively by the number of viruses you eliminate, not by the time you take to finish a level or the quantity of capsules you use. If you conquer the highest difficulty level, you can keep playing to boost your score, although the number of viruses to clear will stay constant. You'll earn bonus points for eliminating multiple viruses simultaneously, but no extra points are given for triggering chain reactions, where the removal of one group of items leads to the removal of another. The game's speed setting also plays a role in scoring, with higher speeds resulting in more points awarded.
