A quick detour while Zen Master waits for your next move: Alexey Pajitnov created Tetris in 1984 after drawing inspiration from pentomino puzzles, then simplified the idea around shapes made from four squares. The timeline takes another interesting turn: Midway's Gun Fight from 1975 was the first arcade video game to use a microprocessor. That long chain of experiments is part of why puzzles still feels fresh when a game finds the right twist.
