LEGO Game Boy Cartridge Mistake! How to Build it RIGHT! (Don't Make This Error) (2026)

Have you ever built something only to realize you did it wrong? This seems to be the case for a number of Lego enthusiasts working with the new Game Boy set from Nintendo. It's hard to believe that it has been 35 years since Nintendo launched its iconic handheld console, but this milestone appears to have led some fans to forget the intricate details of what the original Game Boy cartridges really looked like. This observation stems from various posts on social media and the packaging of a recent Lego set that aims to capture the essence of that classic device.

Released late last year, the Lego Game Boy set, which consists of 421 pieces, quickly became a sought-after gift during the Christmas season. As fans unbox their new Lego creations, many have eagerly shared their builds online, only to be met with corrections from more seasoned fans who spot a recurring mistake.

This exciting Lego set includes two non-playable cartridges designed to fit into the console, mirroring the authentic experience of the original Game Boy. Each cartridge features a distinctive long piece at one end, which is intended to replicate the offset indent characteristic of original Game Boy games. This design was not arbitrary; it aimed to facilitate easier handling for gamers trying to insert or remove cartridges from the device’s slot.

However, if you’ve never had the chance to use an actual Game Boy, or if you’re simply going by intuition, you might instinctively place that long piece right in the center of the cartridge. At first glance, this placement seems logical, doesn’t it? Yet, while many may overlook this detail as a minor issue, dedicated Lego fans have been passionately sharing reminders about how to assemble the set correctly. Discussions have emerged in various online threads where people confess to initially misplacing the cartridges, even if they later made the necessary adjustments. This confusion has affected both longtime fans of the portable console and newcomers who may never have laid hands on a Game Boy before.

One user on Reddit shared their experience, stating, "I put it in the center for my first cart, then noticed the proper placement when making the second cart. I didn’t have a Game Boy growing up so didn’t know that was what the carts were supposed to look like." Another frustrated Lego enthusiast voiced their concerns in a Facebook group, saying, "So far, on every [Game Boy] post I've seen, the cartridges are being built wrong. Please stop centering the top tile and offset it so that it has the notch the original GB games have."

Responses to these revelations have ranged from surprise to appreciation for the helpful tips that can lead to a more accurate build. However, it’s worth noting that the confusion surrounding the correct placement of the pieces isn’t entirely the builders' fault. In fact, the official Lego box for the Game Boy set even depicts the cartridges incorrectly in one of its images, adding to the potential for misunderstanding among fans.
