A strange little side quest
Put Samurai Kin next to the history of puzzles and a few unexpected connections appear. Alexey Pajitnov created Tetris in 1984 after drawing inspiration from pentomino puzzles, then simplified the idea around shapes made from four squares. It also connects to a different milestone: Midway's Gun Fight from 1975 was the first arcade video game to use a microprocessor. Not bad for a few facts hiding behind a Play button.
