Picross DS preview at IGN.

"When it comes to puzzle games, I'm not usually the guy you'd go to. Crosswords make me cross-eyed, word jumbles often cause hemorrhages in my brain, and aside from the "uber-hard" word searches there aren't too many logic or word puzzles I can really get into. Once sudoku hit DS along with Brain Age, however, I was hooked, and while I'm not the best logic puzzle guru out there (I'm more prone to online matches of Tetris DS than going head-to-head with local sudoku pro Craig Harris) DS got me absolutely hooked on the game."
