# Roblox vs Pieces Builder

The clearest difference is ads: Roblox at none against Pieces Builder's shown. Roblox also leads on ratings volume (20M vs 1.6K) and chart position (#1 vs unranked). Pieces Builder's advantage is rating (4.8 vs 4.5) and iOS requirement (10.0 vs 14.0). On price, review sentiment, update cadence 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 Pieces Builder sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Pieces Builder holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Roblox has 20M ratings behind it against 1.6K, so its average is the more settled of the two. Written reviews point the same way: 60% of Roblox's written reviews are positive against 62% of Pieces Builder's.

Roblox ships an update weekly, Pieces Builder every 11 days. The most recent releases landed on September 27, 2026 and September 18, 2026 respectively.
