# Roblox vs World Builder 3D

Roblox and World Builder 3D both sit at 4.5 stars, but that hides the real split: 60% of Roblox's written reviews are positive against 17% of World Builder 3D's. Roblox also leads on update cadence (weekly vs every 6 months) and ratings volume (20M vs 363). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Roblox sells 16 in-app purchases, starting at $4.99 per month and World Builder 3D sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.5 for Roblox against 4.4 for World Builder 3D. That said, the two scores are not equally well evidenced: Roblox has 20M ratings behind it against 363, so its average is the more settled of the two. Written reviews are what separate them: 60% of Roblox's written reviews are positive against 17% of World Builder 3D's.

Roblox ships an update weekly, World Builder 3D every 6 months. The most recent releases landed on September 27, 2026 and August 10, 2026 respectively.
