Kuiki Uhabi Suigou is one of those weird, obscure N64 puzzle games that somehow got stuck in Japan—but if you dig deep enough, it’s actually kind of a hidden gem. The whole thing feels like a mix between a logic puzzle and a board game, where you’re sliding tiles and redirecting streams of water (or something like that—the menus are all in Japanese, so I had to wing it at first).

It starts simple, but after a few levels, you’ll be staring at the screen trying to figure out how to reroute pipes without flooding the whole grid. The music’s oddly relaxing, though, which helps when you’re stuck on a level for 20 minutes. Definitely not for everyone, but if you like slow-burn strategy stuff, it’s worth digging up.
