# Block Stack 3D vs Active Chess

The clearest difference is update cadence: Block Stack 3D at every 6 months against Active Chess's every 39 months. Block Stack 3D also leads on ratings volume (13 vs 1) and iOS requirement (8.0 vs 15.0). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Block Stack 3D sells 1 one-off in-app purchase and Active Chess sells 3 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Block Stack 3D against 5.0 for Active Chess. That said, the two scores are not equally well evidenced: Block Stack 3D has 13 ratings behind it against 1, so its average is the more settled of the two.

Block Stack 3D ships an update every 6 months, Active Chess every 39 months. The most recent releases landed on October 3, 2026 and September 23, 2026 respectively.
