A strange little side quest
The mechanics around Tetris 24 have roots that stretch far beyond modern browsers. Alexey Pajitnov created Tetris in 1984 after drawing inspiration from pentomino puzzles, then simplified the idea around shapes made from four squares. And then there is this: Archery first appeared at the Olympic Games in 1900 and returned permanently to the programme in 1972 after a long absence. That long chain of experiments is part of why puzzles still feels fresh when a game finds the right twist.
