Here is a rabbit hole for the next loading screen in Route Digger: Alexey Pajitnov created Tetris in 1984 after drawing inspiration from pentomino puzzles, then simplified the idea around shapes made from four squares.

That history is one reason familiar mechanics can still feel new when they are recombined well.
