Free browser games, sorted by job

Most “free browser games” hubs dump fifty titles into one grid and hope a crawler figures it out. This page is the map. Speed tests measure a clock: reaction time, click speed, aim, typing, spacebar. Memory tests measure a span: sequence, number, visual, chimp. Tools are diagnostics for a dying key or a bouncing mouse. Puzzle is 2048. Casual is the easy set — memory match, tic tac toe, word search, snake — aimed at a general audience, not a children’s corner.

If you arrived from a search for a specific test, use the card. If you arrived from “free online games” or “human benchmark,” start at reaction time and walk the speed row, or open the casual games hub if you want something that is not a percentile. Every page on this list is its own URL with its own article. This index exists so crawlers and humans both have one dense place to stand.
