Sea Tower Solitaire is extremely hard solitaire because it's very easy to get to the point where next move is impossible but this makes the game more interesting for the solitaire maniac players. You might loose quite a few times before you get the hang of it. Best strategy in the game is to notice the important cards in the stacks and try to reach them as soon as possible.
Move all cards to the 4 foundation piles up in suit from A to K. The 4 free cells can hold any card. You can also move multiple cards already in sequence. When a column has no cards you can use it and place any card or stack of cards.
