The port where you insert a game on my son's DSi is broken. It just ejects the game, won't hold. Any help?

Sounds like the clip is broken that holds it down. you could try to put it in there and move the game back and forth inside (not much tho) till it stays. if it dosent work take it back as not not void the warenty ( asuming u have one) if u dont have a warenty then i say get the rite screw socets (flat head electronic screws wil work for now) and try to put it back on
