Explore mode is a special mode to Crawl; whenever you would normally die, you can choose to come back to life, with no limit. Explore mode games don't count as proper games, and are thus not scored. Explore mode can be entered using the + key, unless it has been disabled.
Configuration option explore_mode can be used to start new games in explore mode, or disallow entering the mode at all. Explore mode is disabled in public online servers.
- Wizard mode, a more robust cheating/debug mode.
- Explore mode was added to Crawl in 0.16.
- Explore more is also included in a few other roguelikes, most notably NetHack. Its purpose was to give players some form of cheating mode without having to use wizmode (which requires admin access on certain UNIX systems).
