Most of you will quickly connect this post with our famous Preposterous Puzzle, which goes hand in hand with the original Impossible Triangle. Also, be sure to check Instructables for tutorial on how to create this toy for yourselves. You can see this puzzle in action via embedded video below. Hope you like it! Btw, you can see more of greeenpro2009′s optical illusions if you check out his YouTube channel.

Some of you may remember, how few months ago we’ve posted a peculiar illusory toy, named Dice Mirror. After seeing such an amount of positive reactions, I decided to share another interesting puzzle which is also available to wider public. This one is called Preposterous Puzzle, and logic behind it, closely relies on optical illusion principles.

Our assignment is relatively simple: what we have to do, is rearrange the wooden blocks, but in such way that one extra slot is retrieved, where additional wooden square can be placed. Sounds somewhat impossible, ayeh? Well, contrary to our belief, the answer exists. I kid you not!

You can get the scoop of what I’m talking about via images included, but the problem can be understood better, if you check one of our previous illusions called Missing Piece.

Let’s repeat the core: At first glance you see a square completely filled with wooden pieces. Then you’re asked to insert a smaller square into the middle without removing any pieces. Obviously there is just not enough space. Apparently no-one told the makers of this puzzle that it’s inherently flawed and unsolvable. But is it? The Preposterous Puzzle can be solved indeed, however refuse to open your mind, and it will silently taunt you forever. Using our cumulative optical illusion experience (check this one), I believe we can solve the puzzle in no-time. If you like this optical illusion toy, it’s available for purchase in our partner store!

To be sincere, I played this for half an hour, but then I got stuck with some colorful cubes. You’ll know what I’m talking about when you get your hands dirty. I can give you some tips, but wouldn’t want to ruin this puzzle for others. So the only thing I’m gonna say, is look behind the suitcase and don’t overlook the corners ;) Hope we can solve this one together using our combined powers! If you show some interest towards these kind of posts, I’ll make sure to bring more in the future!

Impossible Arch Puzzle

I found this image in my optical illusions folder today, and wondered why I never got the time to publish it. Look at the picture on your left. What do you see? There must be something strange going on here. No way that the arch shown here has the proper top. Or can it? I’ve also included a solution inside this post. You’ll have to click the expandable box to see it. I wouldn’t want to ruin your solving experience before you’re ready to see the answer. Anyway, by looking at the solution everything becomes clear. Why has our brain presumed the column is aligned differently than it actually is? I really can’t tell, but hope some of you will try and explain this through comments.

Yesterday I tipped you about new Facebook vanity URLs. Have you had the time to check them? Hope you managed to grab something short and unique to represent you, like I did. But it seems not many of you actually read what I post. Probably you check only the illusions, which is also fine. But I’m REALLY curious what names were taken by our audience. Would be very nice to see more and more of you using your facebook logins to post comments. Not only does this automatically shows your image next to your comment, but additionally you have an option to share your comment so it appears in your Facebook feed. This way you can help us reach more people (your friends will see that you left a comment on our site, if you approve it). What is your opinion on this?
