Mobile Sudoku Puzzle Games

This cluster consists of mobile Sudoku puzzle games offering large puzzle libraries, difficulty levels, hints, and daily challenges. Entries were dated sporadically from 2010 through 2026, with occasional multiple entries in some years (e.g., 2018 and 2026), but no clear growth pattern. The traction leader is 'sudoku-app' with 3 stars, while the others are at zero.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 20 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
