Earlier this year, Nintendo announced that its Dr. Mario puzzle would return in a new iteration to mobile devices, and now Dr. Mario World has a release date: July 10th. Set to appear on Android and iOS (and available for pre-order via one of these links), it's a free game game with stages where you can either send or receive hearts to other players to exchange extra endurance or beat online in fashion mode.
As one would expect, the goal is to remove viruses by adapting them to similarly colored capsules. The different stages present new challenges and the players have a limited number of capsules. The part that costs money is optional "diamonds" that players can deposit into things, restore stamina or buy new doctors with special abilities instead of waiting for stamina to recover over time or to earn them in gameplay with coins.
