Questions worth answering up front

CLI-Games is a browser-based command line with classic games, story-driven ASCII worlds, practical Linux and security training, live CTF events, and a player network. The same terminal and command vocabulary connect all of it.

No. CLI-Games runs entirely in your browser. Just visit the site and start typing commands. No installation, no plugins, no app store.

Yes. The game library, training, and public site are free to use. Optional subscriptions and donations support development and may include extras, but paying is not required to enter the terminal and play.

Not for most solo games or training. A free account is required when the feature needs a persistent identity, including cloud saves, public scores, multiplayer, community features, and competing in The Range.

Type 'games' to see all available games, then type the game name to start playing. For example, type 'chess' to play chess, or 'minesweeper' to play minesweeper. Type 'help' anytime for assistance.

Type 'help' for the command index or 'man <command>' for a manual page. Useful first commands include 'games', 'daily', 'who', 'wiki', 'profile', and 'range'. Inside a game, 'help' shows the verbs available there.

Yes. The terminal includes a mobile keyboard for common keys and shortcuts. Most games work well on a phone; longer command-line training and live Range events are more comfortable with a physical keyboard.

While playing a game that supports saves, type 'save <name>'. Return later with 'load <name>' or launch the game with the save name, such as 'chess mymatch'. Cloud saves require an account.

Dungeon crawlers are text adventure games where you explore locations, interact with characters, and solve puzzles by typing commands. Try 'accidental-knighthood' for a comedic medieval adventure or 'dial-up-days' for a 90s hacker story.

Each game records its natural result—time, guesses, points, or another game-specific measure—on a rolling 30-day board. Crown Time always belongs to individual players: direct wins pay one player, while crew-earned sources divide the same fixed rate among accepted members. The Players board ranks everyone by their combined total; crew pages show rosters, score boards, and active conquests rather than a second currency.

CLI-Games does not sell personal information, use cross-site behavioral profiles, or run session replay. Accounts, game and community activity, payments, security records, and privacy-minimized product analytics are handled as described in the current privacy policy, where optional analytics can also be disabled.

Run 'bugreport' in the terminal to open the guided report, or email [email protected]. Include what you were doing, what you expected, and what happened instead.

The Range is CLI-Games' live CTF surface. During an event, signed-in players receive a private attack box and investigate a shared isolated Linux target. Anyone can watch the competition or browse completed events.
