Learn how to create a fun indoor mini golf course using household items and a Smartivity kit. Perfect for kids activity and family play.

Quick Answer

You can build a fun DIY mini golf course at home using everyday objects or a dedicated kit like Smartivity Build Your Own Mini Golf. This guide walks you through creating a course that's perfect for indoor play and STEM learning.

Why Build a DIY Mini Golf Course?

A DIY mini golf course is a fantastic way to keep kids entertained indoors while encouraging creativity and problem-solving. It's also a great hands-on STEM activity that teaches basic physics concepts like force and trajectory.

Choosing Between a Kit and Scrap Materials

If you want a structured project with clear instructions and STEM explanations, a kit like Smartivity Build Your Own Mini Golf is ideal. It includes laser-cut wooden sheets and a mechanical golf club. For a more open-ended challenge, use cardboard boxes, paper towel rolls, and cups to design obstacles from scratch.

Steps to Build Your DIY Mini Golf Course

Gather Your Materials: Collect a flat surface (table or floor), obstacles (cups, boxes, ramps), a putter (ruler or toy club), and a ball (ping pong or marble). If using a kit, open the Smartivity box and check all parts. Common mistake: using a ball that's too heavy for the obstacles. A lightweight ball works best.
Design the Course Layout: Sketch a simple 3-5 hole course on paper. Include straight shots, curves, and obstacles like tunnels or ramps. Leave enough space between holes for comfortable play. Checkpoint: ensure each hole has a clear starting point and a cup or target to aim for.
Build the Obstacles and Holes: Cut cardboard into ramps, tape paper towel rolls as tunnels, and use cups as holes. For the Smartivity kit, follow the instructions to assemble the mechanical golf club and tree poppers. Common mistake: making obstacles too high or unstable. Secure them with tape or glue.
Set Up and Test Play: Arrange the obstacles on your surface according to your design. Test each hole by putting the ball through. Adjust ramp angles or obstacle positions to make the course challenging but achievable. Checkpoint: if the ball gets stuck, widen the path or lower the ramp angle.
Add Scoring and Rules: Assign par scores for each hole (e.g., par 3 for easy, par 5 for hard). Use the Smartivity flag points or create your own scorecard. Play a round and track strokes. Common mistake: forgetting to set clear boundaries. Mark out-of-bounds areas with string or tape.
