Yes you can with the 3D switch in the upper right hand corner.
first turn on your 3ds, then look in the mirror and realize you need a life.
If you pause the game on a computer, you can go to options and turn on 3D.
Unfortunately the game was designed to look like it was 3D, but the game does not contain programming that allows the 3DS to turn it into 3D.
Unfortunely yes If you don't turn off the 3D after an hour you start to get headaches.
For the 3DS, the 3D feature does not require 3D glasses to play so you do not need to buy 3D glasses.
No, you can play regular DS games on the 3DS. However the 3D games can only be played on the 3DS :)
They are! I own a Nintendo 3DS, and I was amazed at how good the 3D was. Even the graphics when the 3D is off are good, too!
When using a regular DS game on the 3DS, the 3D slider does nothing.
Those with nystagmus may have trouble seeing the graphics in 3D. In such cases, it would be best to turn the 3D effect off.
LEGO Battles can't be played on the Nintendo Wii. It can be played on the Nintendo DS, DS Lite, DSi, DSi XL, 3DS (without 3D), 3DS XL (without 3D), 2DS, New 3DS (without 3D), and New 3DS XL (without 3D)
As the 3DS is designed to display 3D without the use of glasses, using 3D glasses with the 3DS may not give optimal 3D output. You should be able to see 3D depth fine without the need for any glasses.
You can play a DS game on a 3ds but you won't see the game as 3d even with the selection on.
