Links accessed on October 30, 2026. The rules described on this site are primarily those of the Seahaven Towers Solitaire app, as read in its code.

Before each publication, a program checks the 5 example deals and every number on the site:

the deal is recalculated from its game code, using the same shuffle as the app, and compared with the deal produced by the app's code;
52 distinct cards, 10 columns of 5 cards, and 2 cards in the cells;
every move of the solutions is replayed and must be allowed by the app’s rules; the game must end in a win;
group sizes, points and score are recalculated;
the cited rules (cells, foundations, empty column, scoring) are re-read in the app’s code.

Strategy tips are presented as tips, separate from the rules. Found a mistake? Write to us through the contact page.
