Archimedes

Player wiki for [UPDATE!] Obby Creator on Roblox: claim a plot, load Obby IDs, raise your part limit, and use the October 2026 building tools.

What is Archimedes?

Arranges parts along a curve. It shares the 70 Robux correction from 15 January 2025 and the 23 January 2026 part-limit fix with Reflect when the selection includes character models or cart rides. A 30 May 2024-era fix stopped particles being forced outside the obby, and a June 2024 fix stopped Archimedes pushing parts out of bounds.

How do you get Archimedes?

Buy or unlock the plugin and select the parts to arc.

How do you use Archimedes?

Use a short arc first so the curve does not leave the build bounds. Moving parts can be used with it after the 21 August 2024 fix.

FAQ

[UPDATE!] Obby Creator roster questions

What is an Obby ID?

An Obby ID identifies a player-made obby, showcase, or cart ride. Open Load Obby, search the ID or the creation name, and load the match. It does not grant Cash, Gems, or parts.

Are there Obby Creator promo codes?

The developer update log does not publish a promo-code list, and no code string was supplied for this game. Do not type your Roblox password into a site that promises codes. If the game later adds a redemption control, it will be inside the official experience.

How do I raise my part limit?

On 21 August 2024 the developer set a 600-part base, plus 100 parts for Whirlpool Studio group members and milestone rewards for likes and playtime. Open the trophy icon beside the Part Limit counter to see your own milestones. Later logs raised the purchasable cap and, on 9 October 2026, granted 100 parts to existing players who rejoin.

What changed in October 2026?

The 9 October 2026 log added six parts, a repeatable 15-minute Advanced Tools trial from a video ad, wider plots, new edit handles, a Sound Search plugin, sponsored gates, and forced first person. Buttons can activate most parts, but not other buttons. A 10 October follow-up changed Donation Parts so they open the donation screen.

Can friends edit the same obby?

The game description says you can build alone or with friends. Shared edit access can change the build, so only add people you trust, and use the numbered revert screen if a change needs to be rolled back.
