Pushmo (known in Europe as Pullblox) is a downloadable game from the Nintendo eShop for the Nintendo 3DS, developed by Intelligent Systems and published by Nintendo. It is a puzzle game, in which players must push and pull block patterns in order to create steps and platforms, in order to rescue a child trapped within the block structures. It was follow-uped by two sequels, Crashmo on the 3DS, and Pushmo World on Wii U.
Gameplay is relatively simple. You push and pull blocks in a structure to climb up and rescue the child. The difficulty comes from arranging the platforms so you can climb up since you can only go up one step at a time. There are 2 modifiers that add to the gameplay; the manholes and pullout switches. The former allows Mallo to travel between the two points as long as both sides aren't covered. The latter pushes out all blocks of its respective color and sometimes pushing off Mallo. There are in total 250 puzzles in the game plus additional levels that can be added through scanning QR codes.
