Which Nintendo game is the best-selling title for the original Nintendo Entertainment System?

Super Mario Bros. is the best-selling game for the original Nintendo Entertainment System (NES).

Nintendo released the platform game in Japan in 1985, with Shigeru Miyamoto directing and Takashi Tezuka serving as co-director. Players guide Mario through the Mushroom Kingdom to rescue Princess Toadstool from Bowser. Its side-scrolling design, power-ups, hidden areas, and precise controls made it a defining NES experience.

The game is often discussed alongside Duck Hunt because both were bundled with many NES systems in North America, but they are separate titles. Super Mario Bros. also helped establish Mario as Nintendo’s central mascot and popularized conventions used by later platform games. It sold more than 40 million copies on the NES, although later re-releases and ports are counted differently in some sales comparisons.
