Summary: This game is one of my go-to games every time I pick up my Nintendo 3DS! I got the digital download from the Nintendo eShop so I don't have to worry about changing out my game cartridge. I also have the Puzzler World 2012 3D collection as well as Puzzler World and Puzzler World XL! I also have two Puzzler games on my iPad as well! What I love about these games are the variety of puzzles that are available. There's no having to "unlock" certain puzzles in order to play.
