What is a Pathfinder?
Take a look at the completed Pathfinder puzzle on the right hand side.
The puzzle shows a path that moves from the top left to the bottom right corner. The path starts at number 1 and then passes through a number 2, 3 and 4 before starting again at a different number 1.
Each number in the grid must appear in the path but can only be used once. Please also notice that the path can cross over itself.
Obviously the grid on the right shows the solution. The actual puzzle will present the grid without any of the path displayed. Hover over the grid to see the starting puzzle.
Please take a look at some examples of Pathfinder to try this puzzle for yourself. If you need more help then feel free to take a look at this tutorial.
