Questions parents ask
Is this an advent calendar book?
Yes, in puzzle form. Days 1 to 23 each hold three puzzles, and Christmas Eve holds the final Master Code.
What if we start late?
Nothing breaks. The days are numbered rather than dated, so a child can do two days in one sitting and still reach the Master Code by Christmas Eve.
What kinds of puzzles are inside?
70 puzzles in all: Sudoku, ciphers, mazes, crosswords, word searches, number puzzles, drawing challenges and visual logic, each rated easy, medium or hard with snowflakes.
Do children write in the book?
Yes. There is room to solve directly on the page, with a completion box for each mission and answer keys at the back.
Is there a prize at the end?
The Master Code leads to a secret reward, and children who finish can make a Master Code-Breaker certificate with their name on it at bumblebookshelf.com/26gift.
What age is it right for?
It is written for ages 8–10; Amazon lists the reading age as 7–12. Younger solvers tend to want a grown-up nearby for the harder snowflake puzzles.
