ひみつ解読セット - つるつるフィンの事件

Kept my 8-year-old busy for the entire flight to Denver, which honestly never happens. The decoder wheel is the star here, and she loved cracking the clues to figure out who took the flippers. Compact enough to toss in a backpack, too.

My nephew tore through this on the plane, and I was shocked how quietly the decoder wheel kept him busy for a full hour. The case's mystery clues actually made him think instead of just flipping pages. He's already asking for another one.

My six-year-old was glued to this on our flight, and the decoder wheel kept her busy way longer than any screen ever has. It's compact enough to toss in a backpack, and the mystery had her genuinely thinking like a detective.
