How the examples are verified

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, columns of 1, 2, 3, 4, 5, 6 and 7 cards, 24 cards in the stock;
• every move in the games is replayed and must be allowed by the app's rules; the game must end in a win;
• the score and the number of actions, draws and recycles are recalculated and compared with those of the app;
• the rules cited (empty column, foundations, stock, Normal and Vegas scoring) are re-read in the app's code.

Strategy tips are presented as advice, separately from the rules. Figures from published sources are attributed to their sources and do not describe the app. Found an error? Write to us through the contact page.
