I thought with this being only a 500-piece puzzle and the words having different fonts and colors would make this puzzle too easy but I was happy to be proven wrong! I did do this puzzle fairly quickly but I didn't feel like I was cheated because it was still challenging and of course, I had to take time to look at the definitions of the words. The puzzle is simple enough to keep from getting frustrated but challenging enough to make you want to keep working at it. The pieces fit together very cleanly, the border is very unique and the circular shape adds a bit to the challenge. Finishing this puzzle was EXTREMELY satisfying and I cannot recommend it enough!
