A new month is upon us which means more competitive building! Are you ready? Here’s the latest bunch of LEGO contests and challenges from all around the AFOL community for May 2025 to help you find some inspiration and motivation to build! There’s nothing quite like a theme or a prompt to take you out of your comfort zone and give you something new to try. Besides, contests are the perfect place to interact with other contestants and judges and get to know your fellow builders. And if you’re like me, a deadline helps make sure you actually finish!
We’ve listed them in order of deadline so you can plan your building time to the best advantage. Make sure to check the LEGO activity calendar for local challenges and events near you. Here at BrickNerd, some of our fondest memories, greatest building achievements, coolest trophies, and best friendships came from LEGO contests, so we really hope you try some of these out. We look forward to seeing what you build!
