Seahaven Towers is a Patience card game that uses a deck of 52 playing cards.
Seahaven Towers (solitaire) Wikipedia
Game play is very similar to FreeCell, except that cards are built down in suit, and only a king or a sequence starting with a king may be placed on empty tableau spots. There are ten columns, instead of eight. In the initial deal five cards are dealt to each column, leaving two cards in hand.
The suit restriction makes the game more difficult. This is counterbalanced by there being more columns of fewer cards.
Seahaven Towers was originally created by Art Cabral and released as a shareware application for the Macintosh in 1988.
Art Cabral's original Apple Macintosh version was released in 1988 and re-released for Mac OS X in 2002 and Windows in 2003.
A Seahaven Towers card game was provided with the Silicon Graphics, Inc. IRIX operating system. This implementation included an automated solver that could determine whether a particular game could be solved.
Seahaven Towers is included in AisleRiot Solitaire, a part of GNOME Games, as "Seahaven".
Seahaven Towers is supported by present (and most past) versions of the open source PySol solitaire implementation, including PySolFC. It is also a built-in game in Pretty Good Solitaire and Wiz Solitaire.
