This or That is a Microsoft Rewards quiz format in which every question offers only two options. It was a regular card on the Rewards dashboard for several years, but the answer sites we follow have not documented a new round since 2023, so most accounts will not see it today. The practice game above uses the same two-option format.
Unlike other Bing quizzes with multiple choice options, This or That simplifies the decision to just two choices - making it quick to play but still challenging. Topics range from geography and history to pop culture and science.
Microsoft rotates through many different themes for This or That quizzes. Here are the most common categories you'll encounter:
Which country is larger? Which city has more population? Capitals and landmarks comparisons.
Which event happened first? Who was born earlier? Historical timeline challenges.
Which movie made more money? Which song charted higher? Celebrity comparisons.
Which element is heavier? Which animal is faster? Scientific fact comparisons.
Which team won more championships? Which athlete has more records?
Which dish originated where? Which food has more calories?
