Logic games are great in all sorts of ways and especially because of the reason of maintaining a healthy and yound brain with millions of active braincells still working at the age of eighty. This can only be done by practicing and training your brain in different logic math games where your brain has to work a bit extra to figure out the results the game designer has been thinking of. By having a trained logic side of the brain, all the other types of IQ will come easier as well. Extremely smart people usually have combined intelligences to create one smart brain, think about Leonardo Da Vinci for example who combined science, math and drawings for example. He created a master brain so why don't you?
