A strange little side quest
Even a quick game like Fruits Mahjong Html5 sits on top of decades — and sometimes centuries — of ideas. Alexey Pajitnov created Tetris in 1984 after drawing inspiration from pentomino puzzles, then simplified the idea around shapes made from four squares. That old idea kept changing rather than disappearing. Archery first appeared at the Olympic Games in 1900 and returned permanently to the programme in 1972 after a long absence. It is a good reminder that simple game mechanics can carry a surprising amount of history.
