Can You Change the Court Surface in Wii Sports Tennis?

No. Wii Sports Tennis offers **only one court**: a standard green grass surface. There are no unlockable clay, hard, or indoor courts.

If you want court variety, surface physics, or deeper tennis simulation, look at:

• Top Spin 4 (PS3/360) — Clay, grass, hard, indoor; realistic ball physics.
• Virtua Tennis 4 (PS3/360/Vita) — Multiple surfaces, arcade fun.
• Mario Tennis Aces (Switch) — Varied courts with hazards, special shots.
• AO Tennis 2 (PS4/Xbox One/PC) — Licensed Australian Open, surface differences.

Wii Sports Tennis is a pick-up-and-play minigame—surface variety wasn't in scope.
