Uncover buried cards. If you can't clearly see a card, right-click it. The card will remain visible as long as you hold down the mouse button.
Play it again, Windows. To play the same hand over, note the game number at the bottom-left corner of the screen, click the Game menu, click Select Game, and then type in that number. It's a fun way to test a different strategy, or to see if a friend could have played the same hand any better.
Plan ahead. Move cards deliberately to establish long runs, clear columns, and bring home aces.
Aces first. When low cards are buried in a column, it's better to dig them out and move them to a home cell early.
Free up free cells. The more available free cells there are, the easier it is to shift cards around. Aim to leave a free cell empty when a move is complete.
Clear whole columns. Whenever possible, move every card from a column and fill it again starting with as high a card as possible—ideally, nothing lower than a ten. Kings are best.
