A strange little side quest
The rules may be simple on screen, but the backstory around Mahjong for Christmas is anything but tiny. 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. It is a good reminder that simple game mechanics can carry a surprising amount of history.
