Fewest flicks wins. ## What you need - Marbles, two or three per player in different colors (have / $5) - A sandbox, a pile of loose dirt or a bag of play sand (have / $10) - A trowel or old spoons, and paper cups for holes (have) - Cardboard tubes and a watering can or spray bottle (have) - A paper scorecard and a pencil (have) ## Before you start - **Marbles are a choking hazard.** Federal rules label them not for children under 3. With a baby or toddler around, count marbles out and count them back in. - **Contact 811 before you dig into the yard.** PHMSA says every dig, however small, needs 811 first so buried lines get marked, and the call is free. A sandbox or sand mound needs no digging. - **Check the dirt first.** Pull out glass, nails and sharp rocks, and skip spots with pet waste or ant mounds. - **Soap, not sanitizer.** CDC says hand sanitizer doesn't work well on visibly dirty hands, like after playing outdoors. Wash with soap and water when you're done. ## Steps 1. **Pick your dirt** (Dad) Use a sandbox, pour a bag of play sand onto a tarp, or use a bare patch of yard after 811 has marked it. Wet it with the watering can until a handful holds its shape when you squeeze it. 2. **Sketch the course** (Together) On paper, draw three to five holes. Each one gets a start, one obstacle and a cup at the end. Let them name the holes: "Volcano Jump," "The Long Tunnel." 3. **Carve the fairways** (Together) Drag a spoon handle or a finger through the dirt to cut a groove about two fingers wide. Pat the walls firm and mist them with water. Press a paper cup into the end of each fairway so the rim sits level with the ground. 4. **Add tunnels and jumps** (Kid) Lay a cardboard tube in a groove and pack dirt over it for a tunnel. Build a little ramp that ends at a gap for a jump. Bank the outside of a turn higher so the marble stays in. 5. **Test and fix** (Together) Roll a marble through every hole. Where it stalls, smooth or steepen the groove. Where it jumps out, build the wall up. Ask, "What did it do? How do we fix it?" 6. **Play a round** (Together) Rest a knuckle on the ground and flick the marble with your thumb. Every flick counts. Off the track? Put it back where it left, plus one flick. Write each score on the card; the lowest total wins. ## If it stalls - If the walls keep crumbling, add water. Damp sand holds; dry sand slides. - If a hole is too hard, swap the cup for a wider bowl or allow a "gimme" within a finger's length. - If they want to bulldoze it, let them after the round. Building the next course is part of the game. - If it rains, move inside and build the [cardboard marble run](/plans/cardboard-marble-run/) instead. ## Variations - **Ages 4–5:** Roll the marble by hand instead of flicking, and keep it to three short holes with big cups. You carve; they decorate. - **Ages 6–8:** The full plan. They keep the scorecard and name the holes. - **Ages 9–10:** They set a par for each hole, add a bridge or a split, and keep a course record to beat next time. - **After rain:** Damp dirt carves best. Wait for the puddles to drain first. - **Dry spell:** Soak the sand with the watering can before you start, and mist the walls as you go. ## Sources - **Marble choking hazard.** Under the Child Safety Protection Act, marbles for kids 3 and older must carry the warning "CHOKING HAZARD - This toy is a marble. Not for children under 3 yrs."
