Mario's Early Years! Fun with Letters

Mario's Early Years! Fun with Letters is one of several educational games of the Mario series. Developed by The Software Toolworks and published by Nintendo, this game was released for the Super Nintendo Entertainment System in October 1994.

It was produced as a successor to Mario's Early Years! Fun with Numbers, and is a predecessor of Mario's Early Years! Preschool Fun. The concept of all three games is largely identical; they only differ in which tasks the player has to fulfill.
