Nintendo Wi-Fi Connection is an online gaming service that links Nintendo DS systems around the world - so you can play with anyone, anywhere.

With Nintendo Wi-Fi Connection compatible games, you can connect from your wireless internet connection at home, or at special hotspots in hundreds of locations around the country; from internet cafés to shopping malls.

In Tetris DS, the Wi-Fi mode lets you compete in wireless two- or four-player battles against friends or strangers. When you clear blocks from your screen, they are added to the screens of your opponent's, scuppering their chances of success!
