# Creator: build and preview {#creator-build-preview}

The Build page separates **Progress** from **Preview**. Initial implementation commonly takes about 15–40 minutes because Creator writes code, checks rules, styles the game, tests interactions, and prepares mobile and offline behavior.

## Follow progress {#progress}

The friendly sequence covers specification, style, game code, tests, and preparation. Activity messages summarize current work; Advanced details contain technical evidence. Creator does not send a completion notification, so return to the page and check the terminal state.

## Stop, retry, and recover {#stop-retry}

Stop is available during the actual initial implementation and is protected against duplicate clicks. A cancelled or failed build keeps a safe summary and recent log lines. Read the reason, correct missing input if needed, and use Retry instead of starting parallel replacement work.

## Inspect and share Preview {#preview}

Preview appears after a playable build and runs in a separate sandboxed origin. Refresh it after changes, copy its test link, or open it in a new tab. Preview readiness proves the files load, not that gameplay is correct. Continue with [Playtest and publish](/docs/en/creator-playtest-publish/).
