There are 10 wine glasses hidden on the board. Uncover every square without knocking one over.
A number tells you how many glasses touch that square. Press and hold (or right click) to mark a glass with a bottle. Tap a number with all its glasses marked to clear around it.
Today's wine deal is hidden under the board. Every square you uncover shows a little more of it, and clearing the board shows it all. Everyone gets the same board each day.
