一個謎題是一種謎語,使得一個條條框框
A brainteaser is a type of riddle that makes one think outside the box. Some brainteasers are easy, some are a little harder, and some can really make you ponder for a while. Often, when you finally hear the answer, you feel ignorant or silly, because it should have been obvious to you. However, brainteasers are fun. Therefore, we keep testing ourselves and hoping we get better at solving them.
