A strange little side quest
Between one round of Line 98 and the next, this is worth knowing: The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. And the history keeps stacking up: Pac-Man went on sale in 1980, and its creator Toru Iwatani famously linked the character's shape to a pizza with a slice missing. That gives Line 98 a little more company than it first appears to have.
