After you’ve finished your around-the-world trip, you’ll have a gorgeous globe to proudly display as proof of your hard work.

Frequently Asked Questions

What kind of skills can I develop from doing brainteasers?

This ultimately depends on the type of puzzle you’re doing.

Verbal puzzles like crosswords may improve vocabulary and general trivia knowledge, whereas others like anagrams can even improve spelling over time. Others like standard logic puzzles can improve math skills and creative problem-solving.

Would I ever really need to use my brainteaser skills outside of the puzzle book?

Actually, yes. More and more companies these days are including a few tough brain-stimulating questions as part of the interview process, precisely because of the skills we listed above. In addition to seeing if you got the right answer, many employers are interested in seeing your on-the-spot thinking process which informs them of other helpful things.
