Not unless the game requires an internet connection. If you put the game in the back, you should be able to play it. Unless you want to play with people around the world, because that would need WiFi.
do not play online that simple or just use wifi
No, you must have an internet connection to play Clash of Clans.
Nintendo wifi connection
You just need a wifi connection
Yes, you must have an active internet connection on your iDevice to play DragonVale.
WFC stands for 'WiFi Connection' meaning it is online play
You can use Wifi on a DSI, if it doesn't work with you then it's probably because you have WPA connection security settings. WPA connection will allow you to surf the internet and go on the DSI Shop etc., but will not allow you to play games over Nintendo Wifi Connection. To do this, you will have to change your settings to WEP so that you can play on Wifi on your DSI. However, WEP is not as safe to use an internet connection as WPA, so be careful. Hope I Helped...

You have to do Wifi connection and get it from Kaitlin.
Yes of course. You'd simply have to play it over a wired connection.
