A strange little side quest
The fun part of looking behind Swampy is seeing how many older ideas are still alive in modern play. A major archery competition held at Finsbury in England in 1583 drew about 3,000 participants. The surprising part is how quickly the next milestone followed. The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. That history is one reason familiar mechanics can still feel new when they are recombined well.
