All 52 cards are dealt face up into eight columns. Move them all to the four foundations at the top right, one pile per suit, from ace up to king.
On the columns, build down in alternating colours: a red 9 on a black 10.
The four free cells at the top left each hold one card while you dig for the one you need.
Any card may go into an empty column. Empty columns and free cells are your working space: use them carefully.
You can move a run of cards at once when there is room to shuffle it one card at a time: with more free cells and empty columns, longer runs move.
Cards go up to the foundations by themselves once nothing on the table could still need them.
Almost every deal can be won; think a few moves ahead. Drag cards, or tap a card to send it to the best spot (tap again for the next option). Undo and hints are free. Every deal has a number you can replay or share: Deal #4821 is the same layout for everyone.
Keys: U undo, H hint, N new deal. Arrow keys move between cards; Enter plays one.
