This Might Be the World's Hardest Jigsaw Puzzle

For advanced jigsaw puzzle players, the standard 1000-piece board is child's play. But imagine if none of those pieces had a cute cat or weeping willow on the front to guide you.

The “Black Hell” puzzle ($26)—or “White Hell” ($30), depending on your color preference—by Japanese manufacturer Beverly features a single solid color on its front. Adding an extra layer of frustration, the company claims its micro-sized puzzle pieces are the “world’s smallest,” suitable only for the nimblest of fingers.

One reviewer said it took him 17 months to complete half the puzzle. Another commented, “This puzzle is the devil reincarnated into an inanimate object!”

Although the front of the puzzle is blank, different patterns are imprinted on its back to help users connect the dots. This apparently disappointed one especially masochistic puzzle enthusiast, who wrote that it was “less impossible than I had hoped.”

The recommended age for this puzzle is 7 years and up, but it’s safe to say that this devilishly hard task is best left to professionals.

While the Black Hell is certainly in the running for the most challenging jigsaw puzzle, it doesn’t top the chart for ones with the most pieces. Amazon sells a 40,000-piece puzzle featuring Disney characters, and there's a massive one from Kodak at more than 51,000 pieces, but it's usually sold out. If you want to just start at 1000 pieces, you can see a larger collection here.

If you’ve gone through all the recipes you had bookmarked on your phone and are now on a first-name basis with the folks at the local pizzeria, it might be time to introduce a new wrinkle into your weekly dinner menu. But instead of buying loads of groceries and cookbooks to make your own meal, you can just subscribe to a service like Blue Apron, which will deliver all the ingredients and instructions you need for a unique dinner.

And if you start your subscription before May 26, you can save $20 on each of your first three weekly boxes from the company. That means that whatever plan you choose—two or four meals a week, vegetarian or the Signature plan—you’ll save $60 in total.

With the company’s Signature plan, you’ll get your choice of meat, fish, and Beyond foods, along with options for diabetes-friendly and Weight Watchers-approved dishes. The vegetarian plan loses the meat, but still allows you to choose from a variety of dishes like General Tso's tofu and black bean flautas.

To get your $60 off, head to the Blue Apron website and click “Redeem Offer” at the top of the page to sign up.

Summer fun will look a lot different in 2020. Many regions are still in lockdown due to the COVID-19 crisis, and even as businesses start to open up, travel remains risky, according to the CDC. But you don't need to go far to take a break from daily life—especially if you live in one of the cities below.

According to WalletHub, these are the ultimate staycation spots in the U.S. The personal finance website rated 182 cities on two main criteria: recreation, and rest and relaxation. Within those categories, they weighed factors like weather, average home square footage, and parks per capita.

Plano, Texas, came in No.1, with a total score of 66.88 out of 100. The city owes its larger-than-average homes to its high ranking. It was followed by Boise, Idaho, in the second slot and Tampa, Florida, in third. You can check out the top 25 cities below.
