Puzzles & Trivia Challenges Specially Designed to Keep Your Brain Young.

399 Games is a fantastic trivia book not only for one but for sharing with others. I'd tried the trivia questions at work and to my surprise people were quite amused and asked where I got it from. So great job!

Love this book. Truly helps improve cognitive ability, long and short-term memory, etc. Everyone that sees my book wants a copy for themselves. Definitely recommend for ages above 25. Some quizzes are hard to answer because I (31yrs old) was not alive for the era that these questions pertain to. But that is not any deal breaker for me.
I seriously do love and appreciate this book and would recommend it to all my friends :)

So far, either we have great memories, which I know we don't, or we haven't hit the difficult questions yet. Having said that, my husband and I do have fun working together on these questions several nights a week, before bed.
