Review: Great Party Favors! - These were part of the Bday Goodies bag for our daughter’s Escape Room themed party! The kids were all 11-12 yrs old and these were a big hit! Kept them busy in the car on way there, they’re super fun, and anything that makes u think is always great!
Review: Fun! - I'm really enjoying these brain teasers! Some of the reviews said they were too small. They are small but there is an advantage to that too - they take up less space for storage and if you want to bring them to friends or family. I was also worried that once you solve one, the rest would be easy but I'm finding that each is a unique challenge. Some reviewers said the metal ones are too easy, but I find that to really understand each so you can reliably solve it quickly takes some work. One of my daughters found them "infuming" but I like the challenge. I bought these because I wanted something other than screens to do when I'm tired at the end of the day that challenges my cognitive abilities but feels like fun rather than work. They fit that role perfectly. I looked at different brain teaser options on desertcart and I think these are the best price for the number you get. Highly recommend.
