Your learning

Hints help exploration. Viewing a demonstration does not measure mastery.

Playing help

Tap a cell to open its keypad; tap again to close. Drag across cells to select several cells; holding first also works. Group edits change pencil notes only and protect committed digits. Undo reverses a group edit in one step.

Beautifully solved.

Your progress

Play without browser bars

On iPhone, open the hosted HTTPS site in Safari. Tap Share → Add to Home Screen, keep Open as Web App enabled if shown, then launch Quiet Grove from its Home Screen icon.

That installed view opens without Safari’s address and button bars by default. Your iPhone still controls its system status area.

Export a progress backup before moving to another website or app view: Safari and installed apps may keep separate save areas.

A webpage cannot remove the surrounding Codex preview controls. Browsers that support fullscreen can use the fullscreen button; Escape exits.
