The LEGO City Seasonal theme (Advent Calendars) are annual LEGO sets released offering a countdown to Christmas. Each set includes 24 small builds, one to be opened and assembled each day from December 1st to December 24th. The calendars typically feature minifigures, tiny vehicles, and festive-themed items, providing a daily LEGO surprise in the lead-up to Christmas.
2021 LEGO Sets
In 2021, LEGO continued its expansion and innovation, introducing new digital-physical hybrid experiences while reinforcing its commitment to sustainability. One of the most notable additions was LEGO VIDIYO, a collaboration with Universal Music Group, designed to let users create digital music videos using augmented reality (AR) and LEGO BeatBits. The theme blended physical collectible minifigures with app-based interaction, but despite its unique concept, it was short-lived and later discontinued due to low engagement.
