Sea Towers Solitaire
Sea Towers Solitaire is a one-deck game, similar to Freecell Solitaire. Unlike Freecell, cards are built down in suit, and an empty column can only be filled with a King. This makes the game quite a bit harder than Freecell, but arguably makes it more fun.
To build 4 same suit rows in the foundation.
How to Play:
Sea Towers Solitaire starts with 10 standard stacks, each with 5 cards. There are 4 freecells (or in this game 'towers'), two of which contain a card when the game starts. There are 4 foundations stacks, all empty when the game starts.
Cards can be moved onto the standard stacks if they are the same suit, and one less in rank. For example, a 10 of Spades can be moved onto a Jack of Spades.
Empty columns can only be filled with a King.
Like Freecell, the game supports power moves. This is just a shortcut way to move multiple cards at once. Unlike freecell, empty columns are NOT used in calculating how many cards can be moved.
Sea Towers Solitaire Example:
Suppose that the initial deal looks like this:
The four stacks at the top-middle of the screen are the 'towers' or freecells). As you can see, two of them contain a card, in this case the 9 and 5 of spades)
With this game you might start trying to access the Ace of clubs, because both cards underneath it can be played without using the freecells.
So, move the 9 of clubs onto the 10 of clubs...
And the 7 of Diamonds onto the 8 of Diamonds...
Now the Ace of clubs can be moved to a foundation...
From this point the next move might be to move the 5 of spades away from the freecell, to free up one of the freecells...
