Can You Tickle Yourself? — A Screen-Free Cipher Mystery for Kids 9–13 (Bestie Knows, Case #1)

Try to tickle yourself. Go on. We'll wait.

...Didn't work, did it? Nobody can — and the suspect has been hiding inside your skull this whole time. Time to find out why.

Bestie Knows: Can You Tickle Yourself? is a 29-puzzle detective story for kids 9–13. Every puzzle decodes one piece of a real neuroscience mystery. The last page has the reveal. The kid does the work. The brain part with the unpronounceable name takes the fall.

QUIT EVERY ACTIVITY BOOK BY PAGE 10?

This one isn't a workbook. It's a mystery. Every chapter ends on a cliffhanger. Real ciphers — Caesar, Atbash, substitution — plus word scrambles, word searches, mazes, and acrostics, all stitched into one detective arc. Crack the code, find the suspect, close the case.

THREE WAYS TO READ IT

Solo in your room. Race a buddy. Or revive family night — tear chapters apart, divide the work, meet at the back for the answer key. Lefty-friendly answer-line layout. Cuttable chapter pages. Reset Button on every page for the days your brain says no.

REAL NEUROSCIENCE, REAL FUNNY

Built on peer-reviewed research, with citations at the back. Also packed with fart jokes, brain freeze, and lick-your-elbow energy. Body humor plus real science is how kids 9–13 actually finish a book — we put both in this one.
