Doctor Smith's laboratory got contaminated by malicious viruses. They are hiding from him in laboratory glassware. Please, help the doctor to disinfect the laboratory and get rid of the viruses, so that he can come back to making his medications to cure the sick. The doctor drops pills inside the flask where the viruses are located to destroy them. Your goal is to position the pills correctly to destroy all viruses in the flask. The virus gets destroyed if it is located in a row of the pills of the same color. The number of capsules in the row is determined by the selected difficulty level. That's why the game can be played both by kids who like fun and adults who like challenge.
