A strange little side quest
The mechanics around Spotlight: Room Escape have roots that stretch far beyond modern browsers. Alexey Pajitnov created Tetris in 1984 after drawing inspiration from pentomino puzzles, then simplified the idea around shapes made from four squares. The broader history adds one more wrinkle. Nintendo's Donkey Kong arrived in 1981 and introduced the character first known as Jumpman, who later became Mario. Not bad for a few facts hiding behind a Play button.
