Verdict
The clearest difference is in-app purchases: Sudokuki at none against RainMaker 4's 7. Sudokuki also leads on iOS requirement (12.0 vs 18.0). RainMaker 4's advantage is ads (none vs shown) and update cadence (every 8 days vs every 3 months). On price and device support there is nothing between them.
