CLUSTER GAME-BROWSER-PUZZLE · 19 ENTRIES · EARLIEST ENTRY 2025-02-17

Browser puzzle games

This cluster comprises 25 puzzle games and apps that are almost entirely browser-based, with a strong focus on Sudoku and other number puzzles, plus a few color-by-number, crossword, arithmetic, and solver tools. The dated entries are sparse early—two in 2020 and 2021—then show a steady trickle from 2025-02 through 2026-07, including a two-entry month in 2026-05. The highest traction is utility-puzzles (1 star), while sudoku_app and Pudoku lag with 0 stars, showing only faint early adoption signals.

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.
