Yup, the polls default to optional and if you're a game dev you can give some coins or virtual currency to sweeten the deal for the players. Badly written multiple choice polls can get as low as a 10% response rate, but well written one (which are optional) can get as high as 70%- to the user it can be fun if written well. What we're learning is that length (brevity is king) plays a bit part of it, as well as speed to load the question.. we had to change our loading order to get better response rates for our users. Also we recommend to put questions at the points that makes sense... eg while waiting for a game level to load, or after a big activity is complete and it's a natural break point... Other point is - we typically recommend questions only go to a small subset of the audience - enough to answer the question you're trying to ask. So most users never see a question...
