9. Sky Keep (Skyward Sword)
Sky Keep is one of the few dungeons in the entire series that doesn’t feature a boss at the end. However, its overall design more than makes up for that, as Sky Keep is in fact one giant puzzle.
The dungeon is basically a grid of rooms that move and change. You have to work with this mechanic, making sure everything fits together just right. The ultimate goal is to collect three pieces of the Triforce and put them together. These three pieces are in three specific rooms, but you can get to them any way that you choose.
By putting rooms together, Link can move forward and each of those rooms contain a smaller puzzle to solve. Some rooms may only lead to dead ends, while others will open a path forward. Sky Keep has you solving multiple layers of a puzzle at once, and even with its lack of a boss, is an enjoyable trial and error experience.
