Browser reaction time games

This cluster consists of browser-based reaction-time games that measure how quickly a player clicks or taps after a visual signal (typically a color change), usually saving ranked scores to a leaderboard under a nickname. The dated history before the index start is too thin to read a shape from — only 3 dated entries exist, so the cluster's early trajectory predates the index or its members are undated. Among traction leaders, misbutton, LJH_TEST, and quicktap-game show activity signals, though all have zero stars.

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.
