Ni No Kuni 2 is about more than just uniting the great kingdoms of the realm. It's also about building your own kingdom, Evermore, and for that you're going to need a Kingmaker. Which is where the Kingmaker's trials come in—a series of tests to prove yourself that you'll encounter only a few hours into the story.
The second trial is a good old-fashioned boss fight, but the first is an intriguing series of three puzzles. You can beat each puzzle simply by arranging and activating its statues in the order specified by its matching anecdote without doubling back or crossing your own path. But to truly master a puzzle and earn maximum rewards, you've also got to collect the orbs scattered around it by carefully planning your route. Collecting all of them earns you a sword, wand, and consumable for Evan to use in the boss trial, so it's worth doing.
Collecting all the orbs is harder than it sounds, and frankly you deserve a break after the coup you just endured, so I've put together some GIFs showing the perfect solutions for each puzzle. You can pause or skip around these GIFs to review specific portions, as they get pretty complicated.
