The telltale sign of a well designed game is "easy to learn, hard to master."
Ive only been playing single player since I got it and I feel like I already got my moneys worth. Im in love with columns mode, btw, and Im super impressed with how many Easter eggs are hidden throughout the game.
This game will remain on my i-devices for quite a long while, I think
