A:

Numbrix puzzles, which appear weekly in Parade magazine, were created by Marilyn vos Savant, who held the Guinness World Record for highest IQ from 1986 to 1989 and is a columnist for Parade.

The goal of solving a Numbrix puzzle is to fill a grid with consecutive numbers starting with the lowest number, which is provided, and ending with the also-provided highest number. In easier puzzles, additional numbers are also provided throughout the grid. The numbers must be adjacent to one another horizontally or vertically; in Hidato, consecutive numbers may also be diagonal, but not in Numbrix.
