LEGO DUPLO 10450, Hopsy's Castle Game, is a 2025 set built around a castle and a simple board game idea. It belongs to the Duplo theme and contains 47 parts, with animal figures mentioned in the French retail title.

This set places Hopsy’s castle within the LEGO DUPLO range. Its subject is not only a small castle build, but a play activity that combines construction with a board game format.

The French retail title, however, refers to 3 animal figures, a castle and a board game with a wheel.

The model is aimed chiefly at play and guided interaction, while still being relevant for collectors who document DUPLO releases. Within the 2025 Duplo range, it can be placed as a set that joins a castle setting, animal characters and a simple game mechanism. That makes it different from more purely scenic DUPLO builds.
