What this preview stores
The game code does not set browser cookies. It uses local storage for display preferences, custom board colors, practice statistics and the current attempt with up to 100 Undo/Redo snapshots. Local storage remains on your browser rather than being attached automatically to every web request.
The settings are written when you change the theme or save/reset board colors. They do not have a fixed expiry in the current code and remain until overwritten or cleared. Practice records and resumable progress are updated when you act in the game. They remain until overwritten or cleared; the last ten attempts are displayed in history. There is no account or cross-device sync.
Manage your settings
Use the theme button to change appearance. Open Customize board colors in the game and select Reset colors to restore the active theme’s board defaults. Reset colors does not remove the separate theme preference.
To remove all saved preferences, clear site data for this site through your browser’s privacy settings. Your browser may also block storage or clear it automatically.
Cookies outside the game code
The final host, security layer or installed plugins may set additional cookies. These have not been verified in this preview.
