Create a scenario, using something to do with sports, where the console/computer gives the user a set of clues that lead to a correct answer about the topic matter, where only one answer will work. For example, if the answer is beach, a clue could be this is a place with sand and water.

The answer must be a one word answer, and the first letter must be a capital letter (Ex: Beach, Water, Jacob)

The console/computer must check for capital letters.

The console/computer must tell the user if the answer is correct or incorrect and tell it something when those happen as well. (Ex: You are correct ! Thank you for answering this question OR This is incorrect, Please try again)

This must be in a loop until the user gets the correct answer.

Keep in mind if you are looking for Orlando as the answer, but the user types in orlando, the answer is not wrong or incorrect, it just needs a capital letter. So, be specific in what you tell your users...any mistake can make a user stop using your app or think it is broken.

Also keep in mind, if you are looking for Miami as the answer, but the user types in Tampa, and you tell them they are wrong, and wait for the answer again and again, that does not help the user get the correct answer...try giving tips, clues, letters to the word, ask the question in a different way, etc.
