Zoo Keeper 3D is a Puzzle game developed and published by Robot for the Nintendo 3DS. It was released exclusively in Japan on January 26, 2012. This game serves as an enhanced 3D iteration of the original Zoo Keeper series, which began as a browser-based game in 2002 and gained popularity on platforms like the Nintendo DS and mobile devices. In Zoo Keeper 3D, players swap adjacent animal-themed tiles to align three or more of the same kind, causing them to disappear and new tiles to cascade down. The game emphasizes quick thinking and combo creation, allowing players to set up chains by making moves while previous ones are still resolving—a feature that distinguishes it from similar puzzle games.
