Heart-Shaped Maze

Create Free Printable Heart-Shaped Mazes for Valentine's Day and Beyond

Generate free printable heart-shaped mazes where the puzzle is carved inside the outline of a heart. The entrance sits at the top of one lobe, the finish sits near the point at the bottom, and the path winds through the curved silhouette between them. Every wall follows the heart shape, so the finished page looks like a love-note with a puzzle inside.

Download a ready-to-print PDF in A4 or US Letter format for Valentine's Day classroom packs, wedding-stationery activities, anniversary cards, or quiet-time quiet-time activities with a bit of sweetness. Pick the grid resolution, add an optional solution page, and the engine produces a fresh heart-shaped maze every time.

The heart outline makes the maze feel special without changing the solving rules. Underneath the pretty shape is a real pencil-control and problem-solving workout.

Why use this heart-shaped maze generator?

Heart-shaped printables are always popular around Valentine's Day and wedding events, but most are flat colour-in pages. A heart with a real maze inside it is a step up. Use it for:

• Valentine's Day classroom packs
• wedding-stationery activities for child guests
• anniversary cards and love-note stacks
• Mother's Day and Father's Day activity bundles
• quiet-time activities with a touch of theme
• home-school seasonal worksheets
• church and youth-group craft packs

Because every print is random, every page is a unique heart with a unique maze inside.

What you can customise

The controls focus on what changes how the heart looks on the page. You can choose:

• Grid size: smaller for a simple heart, larger for a denser, more detailed one
• Include solution: add a page with the route overlaid
• Seed: reuse a specific heart layout by entering a seed string
• Paper size: A4 or US Letter PDF output

The default 30-cell grid is a sweet spot between visual cleanliness and puzzle challenge.

Notes and limitations

• The size setting controls the number of cells along each side of the bounding square — bigger numbers mean more cells inside the heart.
• The maze occupies only the heart outline; the background is plain white.
• Very small sizes can leave the heart with only a handful of cells; bump the size for more challenge.
• Print at 100% scale for the crispest heart curve.

Who these mazes are for

Children

Primary-age children enjoy the themed shape. Tracing a pencil path around a heart outline supports fine motor skills and rewards careful work.

Parents

Print a stack for Valentine's Day, Mother's Day, or a sweet "just because" activity. Pair it with a pink or red pencil for extra theme.

Teachers

Drop one into a Valentine's afternoon, a PSHE "kindness" lesson, or a classroom valentine-exchange pack.

Puzzle fans

A heart-shaped maze makes a playful alternative to a plain square grid, and higher resolutions give a genuinely tricky puzzle.

How to use the tool

1. Choose the grid size.
2. Turn the solution option on or off.
3. Enter a seed if you want a specific layout.
4. Choose A4 or US Letter.
5. Click Generate.
6. Preview the maze.
7. Download the PDF.

Worked example

A default heart-shaped maze prints at size 30. The page shows a neat heart outline with a small entrance arrow on the top-left lobe and a finish arrow near the bottom point. Inside the heart, narrow corridors wind around through cells that follow the curve of the silhouette. Outside the heart, the page is blank, making the shape pop.

Turn the solution on and a second page prints the same heart with the route drawn in, ideal for a Valentine's card where you want the recipient to know there is a solution waiting for them.

Methodology

A parametric heart curve is sampled at high resolution and rasterised into a binary mask at the chosen grid size. A depth-first search recursive backtracker then walks only cells inside the mask, knocking down walls as it visits neighbours. Because the mask is connected, the algorithm always produces a single solvable maze bounded by the heart outline. The finished maze is drawn on the branded template, with entrance and exit arrows placed at consistent points on the heart.

Designed for A4 and US Letter printing

The PDF supports A4 and US Letter paper sizes. Print at 100% scale for the cleanest curve. The branded header and footer remain consistent across both paper sizes.

Tips for a lovely print

• Print on pink or red paper for an instant Valentine's look without editing the PDF.
• Tuck a completed heart maze into a greetings card for a personal touch.
• Pair with a red or pink pencil and let the child trace the route as part of a card-making activity.
• Save a memorable seed so the same heart maze can be reprinted for partners and friends.
• Combine with the Colour-By-Path Maze for a heart-themed stack that reveals a heart shape twice over.
