Questions

How does PollDepot.com work?

Each question asks you to guess a real number about how surveys and polls are actually conducted. After you answer you see how everyone else guessed, then the real figure and where it comes from.

How is the daily round scored?

Four stats and one opinion poll. A correct guess earns 100 points plus up to 50 for speed, with a combo bonus for answers in a row. The range next to the right answer earns 40. Opinion polls earn 25 for having your say, and nailing every stat adds 150.

Where do the numbers come from?

Every stat links to its source, such as government statistics agencies, research organizations and industry groups. Figures are checked against the source before they go live.

Is it free?

Yes. Playing, streaks, badges and leaderboards are free, and your votes stay anonymous.
