Here is an overview of the game, via its official website:
Use your puzzle skills to eliminate pesky viruses!
Match capsules with viruses and watch them disappear! Simply match three objects of the same color vertically or horizontally to clear them. Take your time, because each puzzling stage’s configuration of viruses must be cleared using a limited number of capsules.
Rid the world of viruses with Dr. Mario and friends!
A colorful cast of viruses has Dr. Mario’s world in a panic! Dr. Mario and friends have put on lab coats and grabbed capsules! Now they’re ready to eliminate those unruly viruses. Hundreds of stages over many different worlds need saving, with new worlds coming on a regular basis!
Play together with friends and family around the world!
You’re not in this alone—send and receive stamina-giving hearts to use in stage mode! Then, show off your puzzle-solving progress. In versus mode, you can challenge others to a one-on-one showdown!
Dr. Mario World is due out for iOS and Android devices on July 10.
