A strange little side quest
A small trivia drop for Puzzle Box: Alexey Pajitnov created Tetris in 1984 after drawing inspiration from pentomino puzzles, then simplified the idea around shapes made from four squares. Another piece of context lands nicely beside it: 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. The details change, but the appeal of learning a system and trying again is remarkably persistent.
