A strange little side quest
Dora Math Game may feel immediate, but the ideas around puzzles have been evolving for a very long time. The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. The same trail leads to another fact: Reader Rabbit's 1986 arrival was part of a major expansion of educational computer software before the CD-ROM boom of the 1990s. That history is one reason familiar mechanics can still feel new when they are recombined well.
