Back From the Klondike
This maze was among the many puzzles Loyd created for newspapers beginning in 1890. The numbers in each square in the grid indicate how many squares you can travel in a straight line horizontally, vertically, or diagonally from that square. For example, if you start in the red square in the center, your first move can take you to any one of the three yellow squares.
1. [Easy] Can you travel from the red square in the center to the topmost green square in just two jumps?
2. [Challenging] Can you figure out how to jump from the red square in the center to each of the other three green squares? The trip to one of the squares will take two jumps, the next three jumps, and the last one four jumps.
3. [Difficult] Loyd’s original challenge was to figure out how to move from the red square in the center to one of the purple squares around the edge. The final jump must land on a purple square without passing over any other purple squares. Here’s a big hint: All but the last jump are along a single straight line.
