A strange little side quest
A quick detour while Sudoku Quest 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. There is another connection worth keeping in the same mental pocket: Pong was field-tested in California bars in 1972 and helped launch the modern arcade-game era. That is the kind of background detail that makes another attempt at Sudoku Quest feel a bit more connected to the history of play.
