The Roblox game Inflation World appears to have been on Roblox since March 28, 2018 based on its game listing.

Quick Scoop

  • The listing title is “inflationfan’s Inflation World (Updated)”.
  • The page snippet shows a date of March 29, 2018 , which strongly suggests that was the release/listing date on Roblox.
  • I couldn’t verify a newer official launch date from the information available here, so the safest answer is 2018.

What that means

If you meant the original Roblox release, the best available evidence points to late March 2018.

If you meant a new version, remake, or update , that would need a separate official post from the creator, because the listing I found only confirms the game’s Roblox presence and early date.
