Free games worth your time

Free usually means ads, timers or a paywall halfway through. These games are free because a research project, a public broadcaster, a non-profit or a developer chose to make them so, and each one is worth a child's attention on its own terms.

Who it is for: Players who want something worthwhile without spending anything, and teachers looking for games that run in a browser.
What is inside: Eleven games from age three to teens, most playable in a browser: PBS KIDS games, free chess, robot programming, logic puzzles, a decree-by-decree kingdom sim, two history and civics games, a factory puzzle, a text survival game and two citizen-science puzzles.
How we chose: Free means free: we checked the store or website on the compiled date and excluded games that need a subscription or a purchase to keep playing.
No advertising inside play; optional extras such as a paid PC edition are noted on the game page, never required.
Store prices are refreshed automatically, so a game that stops being free drops out of this list at the next review.
Quality first: nothing is here only because it costs nothing.
