### ⭐⭐⭐ 







  
    Muy sencillos
  
  

*by A***O on Reviewed in the United States 🇺🇸 on October 30, 2022*

A pesar de ser los “más complicados”, se resolvieron muy fácil, estoy en busca de más retos

### ⭐⭐ 







  
  
    It was already opened.
  

*by B***I on Reviewed in the United States 🇺🇸 on December 19, 2022*

Package wasn’t sealed, box looked dingy around the creases and there was dirt inside one of the cups with the item. This was intended to be a gift but I could never give this to someone. Very disappointed.

### ⭐⭐⭐⭐⭐ 







  
  
    Nice brain teasers
  

*by B***Y on Reviewed in the United States 🇺🇸 on August 18, 2021*

These three nice brain teasers are progressively more difficult. They come with directions, but they only help so much. These are just like the 'brand name' puzzles but at a fraction of the cost. Yes, they are worth the cost. If you like these types of puzzles, you'll enjoy these, and so will your kids.
