Competing for attention alongside organizations like ASML, Rabobank, CapGemini and NS (Dutch Railways), we designed a hands-on challenge to draw participants to our booth. The task: build a LEGO® bridge using Java code. Each brick featured a snippet of Java, and participants had to assemble the bricks in the correct order to complete the code. When the code was assembled correctly, it formed a LEGO® bridge. Building a physical bridge with the LEGO® pieces earned extra points. The fastest builder could win a LEGO® globe.
The challenge was a hit! Many developers – solo or in pairs – gave it their best shot. It was great to watch the different strategies unfold. Some participants carefully mapped out the code before touching a single brick, while others dove straight in. Some prioritized structural stability, while others focused purely on speed. The winning time? An impressive 1 minute and 25 seconds!
