Hi, Psychduck -- there are a bunch of ways to do this. Here's a community thread from chaudhry_ahmad that explains it well: Embedding an iFrame into Qualtrics — Qualtrics Community
You can also embed a Google Form, I think, to gamify a survey... we have tried that with some succss in our organization as well.

I'm currently also trying to put in a game that will allow me to have their score and use this as embedded data for a later question in the same survey. I looked at the thread Adam shared but don't see anything there. Did you find out how to do it?

vanessaistrying Not sure--I'll keep looking--but I seem to recall that there's a way to embed answers into skip logic or to display in another question.
