Letter-Go-Round is a 1984 Sesame Street video game published by Hi Tech Expressions, originally for the Apple IIe. The game teaches letter recognition and simple word formation, and stars four Sesame friends -- Big Bird, Cookie Monster, Ernie and Bert.
The game has six mini-games: Upper Case Matching, Lower Case Matching, Mixed Case Matching, One Little Word, What's Missing?, and Spell the Secret Word.
In the matching rounds, a Sesame character brings a letter onto the screen. The player must match the character's letter with the corresponding letter on a spinning Ferris wheel. In the word completion rounds, the character carries part of a word, and the player must complete the word with a letter from the Ferris wheel.
