About This Product
Direct from US Personal Import Adult
Engineering thinking Patience Mechanical assembly Precision

Marble Night City is one of ROKR's signature kits — a large-scale wooden marble run built around a stylized cityscape. Around 300 pre-cut wooden pieces assemble into a tall structure with cascading tracks, gravity gates, spiral drops, and a marble lift mechanism that returns the marble to the top so the run is continuous.

The build is genuinely engineering-grade. You're constructing working mechanical systems — gear trains, pulley mechanisms, sliding gates — all from wood. Watching a finished marble run cycle a marble through the whole sequence is genuinely satisfying.

One of the larger, more involved kits in the ROKR lineup. Builders typically spend 15-25 hours across multiple weekends. Once complete, it's a permanent piece — kids and adults alike will release marbles through it for years afterward.

What's Included
  • Approx. 300+ pre-cut wooden pieces
  • Marbles (steel balls)
  • Mechanical components — gears, lifts, gates
  • Assembly tools (sandpaper, graphite lubricant)
  • Detailed multilingual instruction book

Apply the included graphite lubricant to all moving parts as the instructions indicate. Skipping this step results in stiff gears that bind under load. Don't substitute oil — graphite is correct.
What to Expect
Hours 1-4: Sort & PlanSort pieces. Identify the main structural components vs. moving parts. Read the entire instruction sequence.
Hours 5-10: FoundationBuild the base and lower track. Get the foundation solid — everything builds up from here.
Hours 11-16: Marble LiftConstruct the marble lift mechanism. Most mechanical phase — fit must be precise for smooth operation.
Hours 17-22: Upper TracksBuild the upper tracks, drops, and spiral elements. Test with a marble periodically.
Hours 23-25: Tune & TestFinal assembly, lubrication, and tuning. The marble should travel the full course without getting stuck.
FAQ
Q: What if the marble gets stuck during use?
A: Common — usually a small wood burr or misalignment. Light sanding plus a touch more graphite typically fixes it. The instruction book has a troubleshooting section.
Q: Are batteries required?
A: No — the marble run is fully mechanical. Lift is hand-cranked; the rest works on gravity.
Q: Is this the authentic Robotime product?
A: Yes. Sourced directly from US retail and shipped to Korea — the same product available on US shelves.
Q: Is it new and unopened?
A: Yes. Every item ships brand new in its original retail packaging.
Q: How long does shipping take?
A: Orders are dispatched within 1 to 2 business days. International transit to Korea typically takes 7 to 14 days depending on customs clearance.
Q: Can I cancel my order?
A: Orders can be cancelled before dispatch — usually within 24 hours of placement. Once shipped, cancellations are no longer possible.
