Virus Killer

Eliminate all viruses by matching capsules of the same color!

This puzzle game features red, yellow, and blue viruses. Players guide falling capsules, moving and rotating them to align with viruses and existing capsules. Four or more horizontally or vertically adjacent capsules/viruses of the same color are removed. The goal is to clear all viruses from the playing field to complete each level. Game over occurs if capsules block the bottle's neck.

Players choose the difficulty (0-20 levels) at the start of each game, affecting the number of viruses to clear. Three speed settings control capsule descent. Scoring is based solely on virus elimination, not time or capsule usage. Higher difficulty levels offer no increase in viruses to clear but allow for higher score accumulation. Bonus points are awarded for clearing multiple viruses simultaneously, but not for chain reactions. Faster speeds result in higher scores.
