When Mario’s Picross came out for the GameBoy around 11 years ago, it was quite addicting. I somehow managed to miss Mario’s Picross 2 because it was released in Japan only. I don’t plan to make the same mistake this time.
Edit: I added a link to an online version of Picross to my links on the right. It’s pretty fun — but if you happen to be using a Mac, I recommend using FireFox for that site over Safari.
Edit 2: I’ve now purchased Picross DS and I’ve done a mini-review that can be found here.
