Blue Tennis Court in Wii Sports? Doesn't Exist (Always Green)

Impossible. Wii Sports Tennis court is always green (hard court texture). No unlock, cheat, or setting changes it.

Possible confusion:

• Wii Sports Resort: Swordplay Showdown (blue dojo), Basketball (orange court), Cycling (varied).
• Mario Tennis / Tennis Games: Blue clay, grass, hard courts selectable.
• Wii Sports Club (Wii U): Same green court.

If you saw blue, it was a different game or a visual glitch (rare).
