Does the 9 yr old have Nintendo DS? There is a game called Brain Age, as well as one called Brain Academy. These are being recommended by my 11 yr old son. There is also a board game that he loves that I enjoy playing called Top Secret. You can find it at highlights.com. It is kind of like Clue in that you have to collect certain cards for specific people, places, and objects(which are the stolen items).These could work for all of the boys. Are any into music? tigerdirect.com has a small mp3 player (512mb) for only $40. It is not an IPOD but it works fine. Good luck.
