Review on Countdown To Christmas 2022: Fun Brain Teaser Puzzles And Surprises In A Kid-Friendly Advent Calendar With Holiday Party Favors For All Ages! by Corey Listner

I let my 7&10 year olds open this. There are only 2 types of brain teaser puzzles in the entire thing so it got boring for them.The cubes that come apart easily get mixed up if more than one is taken apart.The metal brain teasers are fun, the instructions to solve the metal brain teasers is included. However, at 35 years old, I was unable to complete a couple of them even with the solve instructions.These brain teasers would be fun to open one each day and work on solving it for the day. At some point though, the pieces will get mixed up and it'll be more of a hassle to put them back together.
