S.F.
In my house (only 2), if you're bored, what you're really telling me is that you want to do more yard and house chores. My kids learned from the time they were five that there is always fun to be found somewhere because even the silliest game outside is better than chores.
I have a ton of games from Apples to Apples to Risk lying around and, believe it or not, my teens love playing them. I got most of them cheaply at Wal Mart.
Good luck!
