Topic: Cartridge Slot Will Not Work

So I went to insert my "Sonic Lost World" game into my "NINTENDO 3DS" and it will not load. So I removed it and try it again. No go. Help?

I assume the 3DS works, and Lost World used to work. Do other cartridges work? If so, it's probably the cartridge. If not, something's up with the 3DS cartridge slot.

It's possible that either the 3DS cartridge slot or the game may need cleaning. I sometimes need to blow in my old DS's slot to get dust out to get it to recognize games, but others may have better ideas than me.

Well first off do other games work just fine? If not it's more then likely the game. Did you get the game used or new?

it's probably just dirt(I know it, happens all the time with me) do a good COMPLETELY DRY cleaning on the cartridge's conneting part and on the slot and it might work.
blowing also works but it breaks the cartridge in long term.

New. I got it as a birthday present. And I just tried "Super Mario 3D Land" and it wont show up either.

Ok then its probably the slot get some canned air and blow out what dust and debris might be in there. Then try the games again if that doesn't work you might have to contact Nintendo cause it could be the contacts or something more.

Thanks.
