A strange little side quest
Between one round of Escape Game: Apple Cube and the next, this is worth knowing: 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: In 1958, Tennis for Two used an analog computer and an oscilloscope to turn simple physics into a playable tennis-like demonstration. That is the kind of background detail that makes another attempt at Escape Game: Apple Cube feel a bit more connected to the history of play.
