Magic School Merge is a crafting merge game similar to Merge Harvest and Mergest Kingdom. The player helps a witch named Eveline and her owl familiar, Vivienne, build a magic school from the ground up.
In a magical landscape that features a two-tone green checkerboard landscape and areas covered in fog, the player performs merges of three or more of the same items to unlock new characters and create everything needed to construct the best magic school ever. For example, they might create an item that doesn't merge with anything. Instead, it charges for a while like a battery and then produces important items.
Many items merge in the game. For example, the player can merge wheat sprouts to create stalks that they eventually harvest and turn into flour and chocolate chip cookies. To earn coins and magic keys that dispel the fog and open new areas, they feed Vivienne the cookies and prepare orders. They also merge special mushrooms to create gnome workers.�
Magic School Merge displays the available number of keys, coins and another currency, gems, at the top center of the screen. The player can also claim additional coins by using a pocket watch in the lower-left area after they complete specific tasks and via gift boxes they access with a book in the lower-right area.
