The park where you grandmother lives is in disrepair and due to be bulldozed but, if you and your sister can get it cleaned up, maybe the city will want to keep it.
Magic Heroes: Save Our Park is a match-three game. You have the choice of swapping two items to create straight lines of three or more of the same item, dragging along a chain of three or more of the same item, or selecting a group of three or more of the same item. The object is to make matches over the blue tiles to clear all of them from the board. You are doing these puzzles to get money to make repairs to the city park in hopes of saving it.
As the levels get higher, you will encounter obstacles like green tiles that must be matched so you can match the blue tiles, wooden crates that must have a match made next to them to get to the tiles below, stone crates that must be matched next to to get to the wooden crates below, overgrowth that holds a tile in place and you must make a match with the overgrown item to clear it, etc. As you play, you gain bonus magics to help you like the comb that clears one tile or the torch that clears a double line of tiles in a diagonal, etc.
