A strange little side quest
Between one round of Quiz Mix and the next, this is worth knowing: Reader Rabbit's 1986 arrival was part of a major expansion of educational computer software before the CD-ROM boom of the 1990s. That is only half the story. The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. That gives Quiz Mix a little more company than it first appears to have.
