Blooket is a game engine. Gold Quest, Crypto Hack, Tower Defense and the rest all run on the same plain question set: a stem, up to four options, one or more marked correct. The product is built around hosting that set and rewarding fast, correct answers. Authoring the set is left to you, and the spreadsheet import exists so you do not have to click Add Question thirty times.
That is exactly the gap a teacher hits on Sunday night with a chapter PDF and a Blooket planned for Monday. The template is a fast way to enter questions. It is not a way to write them. This page covers the writing half: upload the PDF, and the tool reads it, picks the testable points, phrases each as a question and builds three wrong options plausible enough to be worth a tap. Blooket runs the game.
Two habits make the import painless. First, ask for four options on every question, because a mix of two-option and four-option rows means checking the Correct Answer(s) number against each row's option count. Second, keep stems short. Blooket does not publish a character limit, but a student playing on a phone during Gold Quest does not read a three-line stem. The same source PDF also works with our core PDF to quiz converter when you want a printable version with a separate answer key.
