I just found out there's a bunch of games included for free within the usr file in the terminal. 1. Open terminal. 2. type emacs and push return (this does not mean the emac computer. it works on all macs...so just type it) a screen with a lot of text comes up 3. push escape 4. press the x key once You should now see m-x at the bottom of the screen. 5. Type tetris and push return to start playing. To see a list of all hidden games open a new terminal window and enter this ls /usr/share/emacs/21.2/lisp/play then push return You're welcome.
