Key takeaways for Sudoku・
Where is it heading?
Casual puzzle traffic is consolidating around competitors with high-frequency live-ops and standardized UI benchmarks. Maintenance-mode updates leave Sudoku・ exposed, as the current ad-gating and UI friction will erode the user base before the next major feature release.
