Verdict
The clearest difference is in-app purchases: 9BLOCK at none against Hyper Sudoku's 3. 9BLOCK also leads on ads (none vs shown) and iOS requirement (15.1 vs 18.2). Hyper Sudoku's advantage is update cadence (every 3 days vs every 3 weeks). On price and device support there is nothing between them.
