Space Invaders Trivia Questions

The cannon was inspired by a simple, generic sci-fi ship design. It was never modeled after any specific real-world tank or weapon.

Creator Tomohiro Nishikado intentionally designed them to resemble squid, crabs, and other marine creatures because he couldn't program realistic spaceships with the era's limited technology.

While Space Invaders popularized high scores, it didn't save them after power-off. That honor goes to later games like 'Sea Wolf' or 'Asteroids'.

Space Invaders was a massive hit in 1978, leading to such high demand for 100-yen coins to play that the Bank of Japan had to triple its minting of that coin.

Nishikado built the original prototype with a joystick, but early testers found it awkward, so he replaced it with the now-famous horizontal buttons for left/right movement.

As aliens are destroyed, the CPU has less work to do per frame, so the remaining aliens actually move faster—a happy accident that became a core gameplay mechanic.

To save costs, the original cabinet used a monochrome CRT with transparent colored overlays on the screen—green for the player, red for aliens—giving the illusion of color.

The sound loop was actually based on a simple four-note pattern from a 1961 song called 'The Ballad of the Green Berets'—not a drumbeat.
