We're all trying to find ways to keep entertained and sane while self-isolating during the COVID-19 level 4 lockdown. Some people are turning to baking, others are vigorously cleaning and many are enthusiastically taking part in home workouts.
But if you're turning to puzzles to soothe the nerves, we would probably not recommend this one.
Japanese company Beverly's answer to lockdown boredom is this 2000 piece, pure white micro-puzzle, with no defining patterns or print.
It's as blank as your social calendar for the next month and has been dubbed "pure hell" by online commenters. To make things worse, the pieces are tiny - that's where the 'micro' comes in - and they're all double-sided.
A warning on the box says the puzzle shouldn't be tried by beginners, will provide an intense challenge even for the most skilled experts and might be most appropriate for masochists.
The monster of a puzzle is listed on Beverly's site for ¥3,300, which is about NZ$50 - a small price to pay for the bragging rights after completing what may be the most difficult puzzle in the world.
If the white, blank canvas isn't your thing, perhaps you could try this silver 654 piece jigsaw puzzle from notoriously difficult puzzle brand Ravensburger Krypt.
Or, you could just do a basic Wasjig, if you would rather hold on to your already fragile sanity during this difficult time. It's up to you!
