# AR戏唐宋 vs Sudoku

The clearest difference is in-app purchases: AR戏唐宋 at none against Sudoku's 1. AR戏唐宋 also leads on ads (none vs shown) and iOS requirement (13.0 vs 15.0). Sudoku's advantage is update cadence (every 3 weeks vs every 2 months). On price and device support there is nothing between them.

Both are free to download. Sudoku sells 1 one-off in-app purchase. AR戏唐宋 asks for nothing beyond the download.

AR戏唐宋 ships an update every 2 months, Sudoku every 3 weeks. Both last shipped on November 3, 2026.
