There is no one secret tactic for winning, but there are a few key things you should remember whenever you play. First of all, it's a game of luck as well as strategy. It can also be played at varying levels of difficulty. In harder deals, you are a lot more likely to end up stuck. So, always remember the luck involved.
Remember to free up the cards beneath the tableaus to start with. Don't take from the stock pile until you have to. One of the single biggest things that can cause problems in a game is placing a king in a blank space from the stock pile. Later, this may prevent you from freeing up essential cards from the tableau decks if you do this.
