Grapple Cart Obby
A Roblox obby where you ride a cart through a sky-high course and swing across gaps with a rope grapple hook, on your own or with a friend in one shared cart.
Updated September 26, 2026.
What is Grapple Cart Obby?
Grapple Cart Obby is an obstacle course (obby) on Roblox, made by the group rng dev and released on August 26, 2026. Instead of jumping on foot, you sit in a minecart-style cart and roll along a track floating in the sky. When the track runs out or a gap opens up, you fire the rope grapple hook mounted on the front of your cart to swing or pull yourself across.
The course changes as you go. It starts on grassy plains, moves into a desert full of cacti, and the official artwork shows a cave section over lava. Falling off the edge is the main way a run goes wrong, so most of the challenge is controlling your speed and timing the hook.
1 player or 2 players?
The game's full name is [1 & 2 PLAYER] Grapple Cart Obby, and the two modes play quite differently:
| 1 PLAYER | 2 PLAYER | |
|---|---|---|
| Cart | Your own cart | One cart shared by two players |
| Who does what | You drive and fire the hook | One player drives, the other handles the hook |
| Brake | Yes, a BRAKE button | No brake button |
| Best for | Learning the course at your own pace | Playing with a friend, if you can agree on speed |
More detail on both in the how-to-play guide.
