Back in 2018, developer TobyFox released a surprise on Halloween for all of his fans, and that surprise was the first chapter of Undertale's sequel, Deltarune. After nearly three years of updates and previews, Chapter 2 has been released after Undertale's sixth-anniversary celebration to the delight of fans. Whimsical as ever in its battles and its puzzles, there are notably some parts of the game that leave fans frustrated. For those finding trouble with one puzzle halfway through Chapter 2, here are the solutions to the light puzzle in Queen's mansion.
Deltarune Chapter 2 sees the introduction of villainess Serial Number Q5U4EX7YY2E9N, otherwise known as just Queen for short. She's a villain in the same vein as the franchise's other characters in that she adores puzzles, games, and has her own quirky sense of humor that fans are adoring. The game has Kris, Ralsei, Susie, and a few other guest characters go on a journey to reach her mansion, which takes up the second act of the Chapter.
One of the first tasks the player needs to accomplish in the mansion after leaving their personalized room made by Queen is to solve a light puzzle dealing with colorful spotlights shining onto the floor. The puzzles play out as most Undertale series puzzles do; seemingly simple, but get harder as they persist.
Queen's First Puzzle
The first puzzle is fairly simple, using three pieces and being made of Queen's face. After some dialogue, the player can maneuver each of the three pieces through rotating where the light falls on the floor in order to fit the shape. Using the order of the switches, the first piece goes in the upper left-hand corner of the face. The second, smaller piece fits perfectly as Queen's chin, and the last one makes up the right side of her face.
The Triangle Light Puzzle
This is where things get tricky for fans, but nowhere near as stressful and hard as Sans' fight in the first game's Genocide route. Once again, using the order of the switches, the first piece fits in the upper right corner of the triangle once rotated. The second piece also clears a corner, as it can fit into the bottom point of the shape just fine.
Skipping the third piece, for now, the fourth piece can be adjusted to fit next to the first. With that in place, it exposes just where the pink, third light should go: the upper left-hand corner.
The Truth to Queen's Final Light Puzzle
Lastly, the player will find a puzzle that doesn't seem to make much sense at all, as none of the pieces match. While it may be tricky to some players, the mean-spirited Susie actually figures it out and tells Kris. "You just need to fill in the whole square thing, what if you just piled them all in the corners?" That's the solution for the puzzle; meaning there are numerous answers depending on how players arrange the lights.
Using the side of the pieces to fit the corners will leave at least one piece left to fill in the whole square, completing it. The picture above can be used as a reference for fans.
With the puzzles complete, fans can enjoy more of Deltarune Chapter 2's story, and explore more of Queen's interesting mansion. The next segment has players reunite with Ralsei, with many more combat and puzzles to experience as the episode of Undertale's sequel still has a lot more to show afterward.
Deltarune Chapter 2 is currently only available on PC through itch.to and Steam.
