50 free Deltarune trivia questions with answers — trivia quiz, new questions added Oct 2026.
Deltarune began as a strange little download that fans of Undertale opened without knowing what it was, and it has grown chapter by chapter into one of the most closely followed role-playing games around. Its mix of bullet-dodging battles, sharp jokes and an unsettling mystery about who is really in control keeps players theorising between releases. This quiz covers the heroes of the prophecy and the classmates, parents and neighbours around Kris, the rulers and oddballs of each Dark World, and the secret bosses hidden off the main path. It also tests the battle system, the alternate route, the links and differences with Undertale, the music, and the story of how Toby Fox and a small team build each chapter. The opening questions suit anyone who has played a chapter or two. Later ones are for fans who have recruited every enemy, found every hidden fight and followed the development news.

Q 01Deltarune creator Toby Fox first got the idea for the game from which experience as a college student?
A fever dream

Q 02Which Deltarune hero was first modelled on Maya Fey of Ace Attorney before becoming a purple, axe-swinging bully?
Susie

Q 03Which goat-like prince from the Dark World acts as the party's gentle healer throughout Deltarune?

Q 04Toby Fox released the first chapter of Deltarune as a free download on which holiday in 2018?
Halloween
Halloween 2018 brought the chapter one day after Fox asked people who had finished Undertale to watch that game's official account. The second chapter took almost three more years to follow.
Q 05At the very start of Deltarune, what happens to the custom avatar, or vessel, that the player creates?
It is discarded

Q 07Which goat-like teacher, who shelters the fallen child in Undertale's Ruins, is Kris's adoptive mother in Deltarune?

Q 08After tearing out the player-controlled soul at the end of Deltarune Chapter 1, Kris draws which object?
A knife
A knife makes for a menacing final shot, but the next chapter opens with Kris's mother scolding them for using it to eat her pie.
Q 09Which salesman in Deltarune Chapter 2, obsessed with becoming a Big Shot, proved a breakout hit with players?

Nintendo Switch 2
Nintendo Switch 2 buyers made it the console's best-selling digital game at launch, ahead of even Mario Kart World. Later chapters were promised as free updates.
Q 11In Deltarune, the soul that Kris repeatedly tears out and the player steers in battle appears as what?
