word brain teaser

I have to admit that I’m a lover of the English language, and a good word brain teaser can just suck me right in! I love plays on words, puns, and all sorts of word puzzles. At one point, I was a crossword puzzle junkie. Alas! I have little time for the fun wordy stuff […]

how many holes brain teaser

I have an interesting brain taser for you this morning. It’s not a hard brain teaser at all. In fact, it shouldn’t take you long to figure this one out at all. Well, there you have it—a picture is worth a thousand words. In this case, it’s actually worth seven, but you get my drift. […]

convex or concave corner cube illusion

Today’s cube illusion was sent into the Might Optical Illusions Facebook page by Kovacs. Thank you yet again, Kovacs! I opened it and immediately thought I was staring at the outer corner of a cube. Then, it looked like it was actually the inner corner of a cube. Then, it looked like just a bunch of […]

matchstick puzzle

I haven’t posted a brainteaser on here in a little while, have I. This morning, I woke up with matchstick puzzles on my mind for some reason. I’m odd, I know. Maybe I dreamed about them, or maybe I’m just meant to post a matchstick puzzle today. Maybe my decision will set a series of […]

Key illusion test

I know this is an optical illusion website, but I have a bit of a puzzle for you guys this morning. It’s a simple little key puzzle, but it’s fun nonetheless. All you have to do is tell me which keyhole this key fits into. This key puzzle may seem easy, but it’s a little […]


It took me quite a while to figure out today’s illusion. It was sent into the Mighty Optical Illusions Facbook page by Patrick C. I can back to the image a few times and finally had to message Patrick to have him tell me what was wrong with this picture! Can you do better than […]
