# Brain Code vs 9BLOCK

The clearest difference is in-app purchases: 9BLOCK at none against Brain Code's 6. 9BLOCK also leads on ads (none vs shown) and rating (5.0 vs 4.6). Brain Code's advantage is ratings volume (1.1K vs 3). On price, update cadence, device support and iOS requirement there is nothing between them.

Both are free to download. Brain Code sells 6 one-off in-app purchases. 9BLOCK asks for nothing beyond the download.

9BLOCK holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Brain Code has 1.1K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 77% of Brain Code's written reviews are positive against 100% of 9BLOCK's.

Brain Code ships an update monthly, 9BLOCK every 3 weeks. The most recent releases landed on October 10, 2026 and September 30, 2026 respectively.
