How can you earn Logic skill points in the Sims 2?

I only know of three ways to get logic skill points: play Chess, look through a telescope, and do the crossWord puzzel in the newspaper. If there are any other ways other than using cheat codes please share.

*you can also play checers ( i think that's what it's called ) ( for chess its brown and black and the other 1 white and balack )*
