Rush Hour from Thinkfun is a classic game popular with adults and children alike. The new version, Rush Hour Safari, replaces the cars with jungle animals, includes 10 junior puzzle cards and comes in a great travel bag.
In the basic game each player builds their own set of interconnecting words - just like a crossword puzzle. The first person to get rid of their share of letters wins.
There are multiple variations though (we frequently make our own up), including a version specifically for play in restaurants whilst waiting for service.
