Christopher O. ★★★★★ Sep 11, 2026

My daughter is obsessed with the Secret Message book and has been passing coded notes to her friends all week. The three separate books mean there's always a fresh puzzle when she finishes one. Kept her busy for hours without a screen.

Stella V. ★★★★★ Sep 10, 2026

Bought this for a long road trip and my 8-year-old barely looked up from the Seek & Find book the whole drive. The secret message book is her favorite though, she keeps decoding notes and passing them to her brother.

The three separate books mean it lasts way longer than a typical activity kit, and my kid loves bouncing between cracking codes and the seek-and-find pages. Even the spiral binding holds up in the car, which is a win for any road trip.
