Yoshi

Yoshi is a falling block game in which the player is given a playing field that is divided into four columns. Monsters, which consist of various Mario enemies, appear at the top of the screen and fall into each the columns, turning into blocks as they land and creating stacks that incrementally grow in height. The main objective is to prevent the four stacks from growing too high by eliminating blocks from the field; a game over occurs when any of the stacks crosses the black line drawn across the top of the play field.
