How to Choose a Spy Gift for a Kid Who Loves Mysteries
- Match the gift to their age. Invisible ink and Outfoxed! suit early grades, while Rush Hour, Gravity Maze and the microscope are rated 8+.
- Build a spy kit. Pair walkie-talkies with binoculars or a pocket scope for a ready-made mission bundle.
- Feed the reader. A mystery novel plus its puzzle book gives a bookish kid clues on and off the page.
- Plan for solo and group play. Logic puzzles are mostly single player, while Outfoxed! and walkie-talkies need a partner.
- Check batteries. The walkie-talkies, Laser Maze Junior and microscope all need batteries that aren’t included.
