Play Denki Blocks! Online
You slide colored blocks together until they stick, trying to form blobs or specific shapes—simple at first, then suddenly you're staring at the screen, stuck on some weirdly tricky puzzle.

Denki Blocks! is one of those puzzle games that seems simple at first—until you realize how weirdly satisfying it is to slide colored blocks around. You start with a grid full of scattered blocks, and all you do is nudge them into each other. When matching colors touch, they stick together in these little clumps. Sounds easy, right?
Then the game throws curveballs. Some levels want you to merge every block of the same color, no matter how messy the blob looks. Others demand perfect shapes, like a neat 2x2 square or a zigzag line. The first few puzzles lull you into thinking it’s a breeze, but by level 10, you’re staring at the screen, muttering, "Wait, how do I even—?"
It’s got that classic GBA charm—minimalist, but with just enough challenge to keep you sliding blocks for way longer than you planned. The shapes start simple, then get delightfully weird. You’ll know you’re hooked when you catch yourself tilting your head, trying to visualize the next move.
