# Marble Run 2D vs Reality Construction Kit

The clearest difference is rating: Reality Construction Kit at 4.3 against Marble Run 2D's 3.6. Reality Construction Kit also leads on ads (none vs shown) and update cadence (every 3 weeks vs every 3 months). Marble Run 2D's advantage is ratings volume (99 vs 33). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Marble Run 2D sells 1 in-app purchase, starting at $4.99 per month and Reality Construction Kit sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Reality Construction Kit holds the better App Store score, 4.3 against 3.6. Both are backed by a comparable volume of ratings — 99 and 33 respectively. Written reviews complicate that: 52% of Marble Run 2D's written reviews are positive against 44% of Reality Construction Kit's, so the app with the better star average is not the one people write more warmly about.

Marble Run 2D ships an update every 3 months, Reality Construction Kit every 3 weeks. The most recent releases landed on October 22, 2026 and October 12, 2026 respectively.
