Yoshi, known in Europe and Australia as Mario & Yoshi and in Japan as Yoshi no Tamago (ヨッシーのたまご, lit. "Yoshi's Egg"), is a puzzle game for the NES and Game Boy featuring the titular character. In this game, the player must stack two of the same Mario enemy on top of one another to clear them. The concept of the game was inspired by Tetris.

The NES version of this game was later released on the Virtual Console for the Wii in 2007, the Nintendo 3DS in 2011-2012, and the Wii U in 2013. It was also made available as one of the 20 NES titles at the Nintendo Switch Online's service launch in September 2018.
