Golf is a quick solitaire game where every card is in plain sight. Seven columns of five cards lie face up over a single waste pile, and you clear them by playing cards one rank above or below the waste card, one run after another. A game takes two or three minutes, and nothing is hidden except the order of the stock. It is free here, with no download and no signup. Every deal has a number you can share, and Hint and Undo have no limit.
The deal lays out 35 cards in seven columns of five, all face up and overlapping so you can see every one. One card is turned onto the waste pile, and the other 16 go face down into the stock.
Golf rewards planning more than any other quick solitaire game, because you can see every card in the columns. Before you tap, follow each run in your head. With a 7 on the waste, a 6 that leads on to a 5 and a 4 is worth more than an 8 that leads nowhere, and the card under each one counts too.
Watch the Kings and the Aces. They are the dead ends of Golf: after a King only a Queen plays, after an Ace only a 2. A King buried deep in a column needs a Queen at the right moment to get out, so dig towards it early and keep a Queen in reserve when you can.
Treat the stock as your budget. There are only 16 cards in it and no second pass, so every stock card spent on nothing is a lost chance later. Play out your runs first, but sometimes a card is worth leaving in place because it can carry on a run from the next stock card.
If you are stuck, Hint points at the card that starts the longest run it can see, or at the stock when nothing plays, and Undo takes back as many moves as you like. Fewer than half of all deals can be cleared, so a lost game is often the cards, not you.
Golf's closest relative is TriPeaks Solitaire, where King and Ace connect and most cards start face down. For another quick game, try Pyramid Solitaire. For longer ones, play Klondike Solitaire, FreeCell or Spider Solitaire.
