Type numbers as words. If you type “twelve”, the eye shows 12. This means you never have to switch your keyboard to the number pad while entering the secret, which could look suspicious. It works from 0 to 100 and forgives misspellings.

If you enter a secret and your question contains one of these categories, the eye answers in a full sentence.

Name, Number, Color, Month, Day, Animal, City, Food

Examples:

• Can you guess what name they are thinking of?
• Can you guess what color Whitney is picturing?
• Can you guess what city Rusty is from?

If you don’t enter a secret and ask a yes/no question, the eye answers like a magic 8-ball.

If you don’t enter a secret and the question isn’t yes/no, the eye gives one of its stock phrases.

• Tap it before you type the secret.
• Tap it again to lock the secret in.
