This might be advertising as well, but there is a company called Thinkfun which makes really good logic games for kids.
I have 4 grandchildren aged from 5 to 19 now. We have been buying these games for them for over 3 years, and I have still got a new one this year. There is even a chess game which comprises of a quarter of a board.
Our 10 year old grandson is autistic. He loves Rushhour and Tipover, and the chess game. His five year old sister was doing his Rushhour when she was 3 , so we bought her her own with an icecream van.
There are sites where you can play online, to see what you think of them.
Even the 19 year old will play these games when she visits.
