A gentle suggestion to all who post riddles, Can you please stop putting the answers straight after the question, as they are so near to the riddle that I and i'm sure others auto read them . Maybe if you put them at the end of the list or upside down more of us can enjoy your hard work, thank you.

To make the riddle more challenging, I think it's best for the answers not to be too close to the question. The point of a riddle is to take a couple of minutes to solve them. So having the answers right below will take from the enjoyment. Try having a system where you click to see the answers.

    The History of Riddles

    It might come off as a surprise to you, but riddles are pretty much ancient! And by ancient, we mean that the first riddles, in the very same format that we know and use today, appeared as far back as in Babylonian times. Mind you, the city of Babylon has existed since the 18th century BC — thousands of years before our days!

    ADVERTISEMENT

    The first attempt to define what a riddle is in a scholarly way was made much, much later than that, though, around the end of the 19th century by Robert Petsch. His work was succeeded by Archer Taylor, who, in 1918-20, did a massive job of cataloging myriads of riddles. 

    One interesting thing he has discovered is that some riddles are almost the same across continents and languages. Take, for instance, the writing riddle about black letters on white paper, the year riddle mentioning something in the count of twelve, and the cow riddle. Because, well, cows. 

    Ultimately, all ancient riddles were based on the things that people saw every day and found of significant meaning. Because where else would you find a greater meaning than in the human experience and condition?

    Why Do People Do Riddles? 

    Intellectual Challenge

    Solving riddles isn't just a leisurely pastime; it's a mental workout that challenges our brains and offers insights into our cognitive performance. This fulfilling activity caters to our dual instincts—one, the desire to showcase our intellectual competence, and two, the primal urge to conquer challenges. 

    Cognitive Exercise

    Essentially, brainteasers act as a platform to display our analytical thinking, problem-solving skills, and mental agility. As we unravel their complexities, we decipher their elements and relish the satisfaction of assembling the pieces into a coherent whole.

    ADVERTISEMENT

    Aha! Moments

    Moreover, riddles tap into our competitive spirit, triggering a determination to succeed. They’re not just riddles to solve; they’re quests to master. The sense of accomplishment that accompanies the final piece falling into place symbolizes our persistence and strategic acumen. In essence, puzzles become a stage upon which we demonstrate both our cognitive finesse and our yearning for victory, encapsulating the concept of being smart in action.

    Higher IQ

    Besides all this fun action and hefty rewards that solving really hard riddles gives us, solving brain teasers for around twenty minutes daily can raise your IQ! This isn’t just anecdotal; it was proved by rock-solid research by Michigan University back in 2011.

    What is the Hardest Riddle in the World?

    You asked for it, we’ve found it! The hardest riddle in the world, dubbed the Polar Bear Riddle or the Harvard Riddle, goes like this:

    I turn polar bears white, and I will make you cry. I make guys have to pee, and girls comb their hair. I make celebrities look stupid and normal people look like celebrities. I turn pancakes brown and make your champagne bubble. If you squeeze me, I’ll pop, but if you look at me, you’ll pop. 

    ADVERTISEMENT

    Now, why is it titled as one of the hardest riddles of all time? Well, the legend has it that 97% of Harvard grads can’t solve it, so if you can, know that they owe you a diploma. 

    And what’s the correct answer to this riddle? We are not going to tell you that because it would spoil all the fun now, wouldn’t it?
