When you play Solitaire Tower, you are trying to move all the cards in the pyramid to the pile at the bottom of the game screen. When this pile is empty, it is represented by a gold box, and you can put any card from the pyramid into it. To place a card into the pile, just click it. Once there is at least one card in the pile, the next card you must place must have a value one greater than or one less than the card on the top of the pile. In the example above, we will click 3 to add it to the pile.
After you click the 3 of clubs, it is moved to the top of the pile. Next we can move the 4 of diamonds, because it is one more than the 3 of clubs, then we can move the 5 of hearts, and the 6 of spades.
Now that we have moved several cards into the pile, we have reached a point where there are no longer any cards we can move to the pile. This is because there are no 7s and no 5s that are completely uncovered. So now we must click the deck next to the pile to deal another card into the pile and change it's top card.
Once we click the deck, a new card will be dealt onto the top of the pile. In this case, it is the King of Clubs. Now we can continue to place cards on the pile.
Because the top card is a King, we can place the Queen of Spades onto the top of the pile. (We could have also placed an Ace if one were available because the Ace is both the highest and lowest card in the game). Once the Queen is on top of the pile we can choose to place either the Jack of Clubs or the King of Spades. Removing the Queen of Spades has freed the 10 of hearts so it makes more sense to go with the Jack of clubs. We will then click the Jack of Clubs, 10 of Hearts, 9 of Spades, 8 of Hearts, and 7 of Spades (Freed when we removed the 8 of Hearts).
Now that the 7 of Spades is on top of the pile we are stuck again. At this point we will click the deck to see if the new top card allows us to continue. We can keep removing cards this way until our deck runs out of cards, or we are able to remove every card from the pyramid.
