Navigrid
Navigrid is a logic-based number-placement puzzle. The puzzler is provided with a set of movements which must be used to move between the numbers 1 to 9 in order starting with the number 1. A solved grid will contain each of the numbers 1 to 9. The puzzle setter provides a partially completed grid.
The puzzle was invented by an English puzzle enthusiast, Laurence May, in 2006 and was first published by BBC MindGames Magazine where it appeared in all 9 issues. It is produced by Vexus Puzzle Design and is currently represented by Puzzler Media. The puzzle appears along with Sudoku and Kakuro in their "Kakuro" magazine.
Rules[edit]
When the grid is completed, it must be possible to use every one of the 8 movements to journey from the number 1 to the number 2, from the number 2 to the number 3 and so on until you can move from the number 8 to the number 9. A movement must not take you through a black square.
Movements[edit]
Both parts of a movement must be used but they can be used in either order. Example movements are shown in the first image above. The first movement represents a move of either two squares to the left and then one square down or one square down and then two squares to the left.
