Grombi trivia break for Clue Hunter: Alexey Pajitnov created Tetris in 1984 after drawing inspiration from pentomino puzzles, then simplified the idea around shapes made from four squares. Another piece of context lands nicely beside it: Spacewar! appeared on MIT's PDP-1 in 1962 and became one of the earliest influential computer games shared among programmers. It is a good reminder that simple game mechanics can carry a surprising amount of history.
