When the kids’ mazes are too easy

Wide-corridor mazes suit young children, but older solvers finish them in seconds. These mazes shrink the corridors to 6 mm, which packs over 1,200 cells onto a page. There are many long dead ends, and the correct route winds across most of the page before reaching the exit.

Tips for solving

  • Start from the end: working backwards from the exit is often quicker.
  • Fill dead ends: shade each dead end back to its junction; what remains is the route.
  • Follow one wall: keep a finger on the left-hand wall and you will always reach the exit in a perfect maze, though not by the shortest path.

Uses

Quiet time on trips, early-finisher work in class, puzzle pages for newsletters and gift booklets, or a relaxing break away from screens. A whole stack can be printed with a different number for each sheet. For younger solvers, use the mazes for kids with wide corridors.

Printing

Print at 100% / Actual size. The solution page shows the route in colour, so print it separately or keep it as a digital file to check answers.

Frequently asked questions

How big is a hard maze?

With 6 mm corridors, a Letter page holds 31 × 40 cells and A4 holds 31 × 44. The very hard variation, with 4 mm corridors, reaches 47 × 60 on Letter.

Is there always a way through?

Yes, exactly one. The mazes are perfect mazes: every cell is reachable and there is only one route between any two points, so there are no loops to shortcut.

How do I get a new maze?

Change the maze number in the generator. Each number gives a different maze, and the same number always gives the same one.

What pen should I use?

A fine pen or sharp pencil. At 6 mm, a thick marker can cross walls; at 4 mm, a 0.5 mm pencil works best.
