Maze
Printable mazes: from large and easy for preschool to fine and tricky, each one newly rolled, with a number and the solution path. As a PDF for A4 or as an image.
Large cells and wide corridors, easy to trace with a pencil.
4 to 80 cells per side, at most 4,800 in total. Entering your own number sets the level to “Custom size”.
Depth-first search: long, winding corridors with few branches.
Start on the top edge, finish on the bottom edge, each at a random spot.
Every maze gets its own No. It is in the footer, and with 2 or 4 per page also in small print under each maze.
1 to 30, each with different mazes, so nobody copies.
1 to 999999. The same No. and the same settings give exactly the same maze. More mazes get the following numbers.
After each: every sheet is followed by its solution. If you print on both sides, the solution ends up on the back; then “At the end” is better.
The preview appears right away.
The PNG shows maze 1 on a white background, with the solution if the preview shows the solution.
When printing, choose “Actual size” or “100%”, not “Fit to page”, otherwise the corridors get narrower than stated.
Saves the settings and the No. as a JSON file on your device. Later, exactly the same mazes come from it.
Goes well with: Math worksheets · Grid and lined paper · All kids tools
Nothing leaves this device. Mazes, PDF and PNG are made here in your browser.
How it works
- 01Choose a level: preschool with large cells and thick walls up to expert with fine corridors. You can also enter width and height yourself.
- 02Set the method, start and finish, orientation and number of sheets. The preview shows sheet 1 right away, with “Solution” also the solution path. If you do not like it, “Roll again”.
- 03Download the PDF and print at “Actual size”. For a worksheet or a presentation, maze 1 is also available as a PNG.
Every maze is perfect. Between any two cells there is exactly one path, without islands and without circles. The tool checks this for every maze before it is shown or printed: all cells are connected, and there is exactly one passage fewer than cells. If the check failed, a message would appear instead of the maze. Only “With loops” then deliberately removes a few more walls (about 6 in 100 cells get an extra passage); then several paths lead to the finish, and the solution shows the shortest.
The methods. “Long corridors” (depth-first search) goes as far as possible and only turns back at a dead end: long, winding corridors with few branches. “Many branches” (Prim) grows from all sides at once: many short dead ends. “Balanced” (Wilson) makes every possible maze equally likely.
Start and finish. The start is always on the top edge. “Top and bottom” puts start and finish at random spots on the top and bottom edge, “Corner to corner” in opposite corners, “Finish in the center” in the center cell. “Longest path” puts the finish at the spot on the bottom edge with the longest path from the start.
The No. Every maze has a number from 1 to 999999; it is in small print in the footer of each sheet. The same No. and the same settings give exactly the same maze, even on another device. More mazes and sheets get the following numbers, so in a class every kid gets a different one. This applies to this version of the tool; if the method ever changes, the page will say so.
The figures. The solution path counts all cells from start to finish, both included. Dead ends are cells with only one exit; the start and finish cells do not count. The corridor width is the free space between two walls on paper.
Limits. Only rectangular mazes and only A4. In the PDF every corridor must be at least 4 mm wide, otherwise it can no longer be traced with a pencil: with more cells the field tells you how many fit at most, and the PDF stays locked. The PNG still works (up to 80 cells per side and 3000 pixels). For preschool, corridors from 15 mm are intended; if they get narrower with 2 or 4 mazes per page, the hint under “Cells” says so. Printing is black on white, without filled areas, the solution path gray.
Nothing is saved. The page remembers neither settings nor numbers. The file from “Save settings to a file” contains only the settings and the No.; when loading, the tool calculates the same mazes again from it.
