LEGO Game Boy’s Cartridges Are Stumping Old-School Gamers

In early January 2025, Polygon noticed that many LEGO Game Boy builders were assembling their kits incorrectly. It’s understandable for those unfamiliar with the original Game Boy, but surprisingly, even veteran gamers are making the same mistake. The error involves the top piece of the LEGO cartridge – many are centering it, when it should actually have a small notch in the top-right corner, just like the real Game Boy cartridges. It seems the issue stems from incorrect assembly shown on the product’s box art.
