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!
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 not only challenges our brains but also 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're not only deciphering their elements but also relishing the satisfaction of assembling the pieces into a coherent whole.
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! And this isn’t just anecdotal but 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'll look at me, you'll pop.
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?

Or, written as, "What word starts with E and ends with E but only has one letter in 'it'?", the answer could be "exile". (It only has one letter of the word "it" in it and ends and starts with "e".) The punctuation of that was a doozy! Hopefully I punctuated all of that correctly! 😅

Lack of Visual Appeal: The webpage lacks visual elements that could make it more engaging and visually appealing. The absence of images or interactive design elements makes the page feel dull and uninteresting.
Solution: Enhance Visual Appeal: Incorporate visually appealing graphics, illustrations, or even animations that complement the riddles. This will make the page more visually engaging and enticing for users.
Lack of Social Sharing Options: The webpage misses an opportunity to capitalize on the viral nature of riddles by not providing easy sharing options. Adding social media sharing buttons would allow users to share their favorite riddles with their friends and increase the page's reach.

Some thoughts:
1. The first paragraphs lack a heading and contain an annoying ad on the left side of the page - the spot where most visitors' eyes linger first (I attach a screenshot of the view below).
2. The formatting of the riddle cards is a common complaint; I'd suggest putting the answer under a spoiler tag.
3. I'd suggest dividing the riddles into 3-5 sections according to difficulty. The reader could see several lists of riddles (20 per list) and wouldn’t need to scroll endlessly. The numbered riddles could be spaced out in a compact manner, still allowing for comments. The heading titles could help drive more SEO traffic, e.g. "Riddles for kids", "Riddles for your family/friends game night", "The toughest riddles for pros".
4. There could be an image for every section, named descriptively and with added alt tags.
5. Some jump links could also be nice so that the reader can jump straight to whatever list is relevant to them. Again, this can be good for SEO.
