'Yes or No' is an educational game that will challenge your brain and help you expand your knowledge in 10 different categories, including cartoons, technology, sports, movies, and more. The game consists of 900 questions that can be randomly displayed on the screen, and all you have to do is answer "Yes" or "No" to confirm or disprove the presented fact.

You will learn amazing facts, such as the fact that Disney once refused to film Back to the Future. Humans spend about a year blinking in total during their lifetime. If all Lego parts ever produced were divided equally among the population of Earth, each person would receive 62 parts.
