What are some good game apps? - 1

I'm flying on a plane tomorrow, and I need something to keep me occupied. I read books but thats not all I want to do. I like puzzle games (TwoDots is a good one I like to play), I also play sudoku and solitaire. Anything addicting and fun to play would be great. I tried looking for some but I'm very picky. I have an iPhone and it would also help if the apps were free.

Bejewled kills alot of time and tetris is a oldie but still challenging. Spider solitaire is better

These games cost money but I absolutely love them: Blackwell legacy, Blackwell unbound, and Blackwell convergence; you can find all three by just searching for "Blackwell" in the AppStore. There are five games total for PC but only those three are on the AppStore. They take about 1-2 hours to complete and are extremely fun and addicting and will be great for playing on and off the plane. 4 games star Rosangela (Rosa) Blackwell (the games with Rosa are legacy, convergence, deception and epiphany.) In unbound you play as Rosa's aunt Lauren.
The games are basically a point and click adventure (which is like a puzzle) and you play as Rosa (or Lauren) and in every game but legacy, get to play as the Blackwell spirit guide Joey, a ghost who with Rosa (or Lauren) helps convince lost souls they are dead and move on. It's not scary but it has some curse words like the D word or the B word and possibly the A word, but that's really it and they hardly curse anyway. I love these games!
