Ever tried solving Go puzzles on a Game Boy? This one's a niche little gem—Ishida Yoshio Tsume Go Paradise is basically a collection of tricky Go problems from pro player Ishida Yoshio. You get dropped into these "tsume-go" scenarios where you have to find the killing move or the perfect defense, and the difficulty ramps up fast.

At first, it feels like you're just placing stones randomly, but after a few fails, you start seeing patterns—like how to corner a group or when to sacrifice a stone. The Game Boy's tiny screen actually works surprisingly well for this, since Go boards aren’t exactly graphics-heavy. If you're into Go (or just want to torture your brain with some old-school strategy), it’s a solid way to kill time. Just don’t expect flashy animations or hand-holding tutorials.
