Is Wii Sports on a Disc?

Wii Sports Media Format

Wii Sports is not on a CD or DVD. It comes pre-installed on the Wii console's internal memory (except in South Korea and later "Wii Sports Club" era).

Details

• Original Wii (2006): Includes Wii Sports on NAND flash—no disc needed.
• Wii Sports disc exists only as a pack-in retail disc for regions/bundles without pre-install (rare).
• Wii U: Wii Sports Club is a separate eShop download (paid per sport or bundle).

Just turn on the Wii and select the Wii Sports channel!
