This is tip 3 of 4 for Pet Rescue Saga 107.
Level 107 Cheat #3: If the viruses to spread.
- Don’t sweat it. You can make matches of two or more viruses to burst them, or simply eliminate them with the Column Blaster Booster. Dont let them spread too much though, because you will need all the normal blocks you can get your hands on to reach the 20,000 goal.
