To copy a link from a Roblox game, open the game’s page and use the share option, then copy the link from there. On mobile, this is usually the three dots on the game page, then Share → Copy ; on desktop, you can often copy the game page URL from the browser address bar.

Mobile steps

  1. Open Roblox and find the game you want.
  2. Tap the three dots on the game page.
  3. Tap Share.
  4. Tap Copy to copy the link.

Desktop steps

  1. Open the game page in a web browser.
  2. Click the address bar.
  3. Copy the full URL with Ctrl+C or right-click and copy.
  4. Paste it anywhere you want to share it.

Quick note

Some tutorials also show that on Android you can long-press the game link in a browser and choose Copy link address.

TL;DR: open the game page, hit Share or copy the browser link, and paste it where you want to send it.
