A strange little side quest
If Rhomb sends you down a curiosity rabbit hole, start here. Alexey Pajitnov created Tetris in 1984 after drawing inspiration from pentomino puzzles, then simplified the idea around shapes made from four squares. The surprising part is how quickly the next milestone followed. Space Invaders, released in 1978, helped push video games into mainstream popular culture. That gives Rhomb a little more company than it first appears to have.
