How the examples are verified

Before each publication, a program checks the 4 example deals and every figure 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: 28 in the peaks, including 10 face up, 23 cards in the stock, 1 card in the waste pile;
• every move in the games shown is replayed and must be allowed by the app's rules; cards turned face up, peaks cleared, score and move count are compared with those in the app;
• for each deal, an exact solver tries every legal sequence of moves, remembering positions already visited: it calculates the greatest number of cards that can be removed. It is implemented twice, once using the app's code and once independently, and the two answers must match;
• the rules cited (covered cards and cards turning face up, adjacent ranks, king and ace, stock, end of game, scoring system) are checked against the app's code.

Strategy tips are presented as advice, separately from the rules. The games shown were found by this program: they prove that a deal can or cannot be won, without saying anything about other deals. Found an error? Write to us through the contact page.
