Review on 💰 Unlock the Challenge: Money Puzzle Brain Teasing Cards by Justin Torres

I bought two of these for my granddaughters, one came with the drawer open so I could put money in and the other with the door closed. Apparently used and sent back. I tried to solve the puzzle without opening the door with a hammer but couldn't, so I put the money through the slot and hoped it would work. My 12 year old granddaughter opened it in minutes but the 10 year old had a hard time. I offered the hammer :) but she took it to her sister who opened it with no problem. Looking back, I'm not sure the puzzles were worth the price, but what's done is done.
