Eliminate all viruses by matching capsules of the same color! This puzzle game features red, yellow, and blue viruses. Guide falling capsules left or right, rotating them to align with viruses and existing capsules. Four or more matching colored halves (capsules or viruses) in a row (horizontally or vertically) vanish. Clear all viruses to win a level. Game over occurs if capsules block the bottle's neck.
Choose your difficulty at the start of each game. Select a level (0-20) determining the number of viruses to eliminate, and adjust the capsule fall speed (three options). Scoring is based solely on virus eliminations, not time or capsules used. Higher difficulty levels offer no additional viruses to clear, but allow for higher score accumulation. Bonus points are awarded for simultaneous eliminations of multiple viruses, but not for chain reactions. Faster game speeds also increase points earned.
