A strange little side quest
The fun part of looking behind Math Walls is seeing how many older ideas are still alive in modern play. The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. And the history keeps stacking up: Nintendo's Donkey Kong arrived in 1981 and introduced the character first known as Jumpman, who later became Mario. So a round of Math Walls is not just a quick distraction; it is a tiny stop on a much longer puzzles timeline.
