About this site

What this site is

Grapple Cart Obby Wiki (grapplecartobby.wiki) is an independent, fan-made English guide for the Roblox game [1 & 2 PLAYER] Grapple Cart Obby by the group rng dev. It is not affiliated with or endorsed by rng dev or Roblox Corporation.

Why it exists

Why it exists: the game's official Roblox description is empty, and as of our first check (2026-09-22) no third-party guide, wiki or code site covered it. New players had nowhere written to learn the buttons, the co-op setup, or the coin economy.

How facts are sourced

How facts are sourced: official Roblox APIs (identity, stats, dates), the game's official art, and dated in-game observations from captured sessions. Every fact carries its check date; prices and behavior can change with updates. Anything we couldn't verify is labeled Unknown — we don't invent values, stage names, or payout rules.

Maintenance

Maintenance: we re-check facts after notable updates. Spot something wrong or outdated? That's a bug in our research, not in your game — send corrections through the contact channel, and read the independence and advertising disclosure for how this site is funded.
