Solitaire Rules

1 pack of cards is distributed over the playing field, without the jokers. If you look at the game you will see 7 columns of playing cards at the bottom, which we call the tableau. Only the top cards are open and are therefore visible. The cards that are not divided, go to the stock pile, which you see at the top left. In the top right are 4 empty boxes, the basic columns, all cards will be placed here eventually, in order from Ace to King and in the same color, this is the main goal of the game. You can do this by sorting the cards on the tableau, where you only can arrange them by alternating color, from high to low. For example, if you see a black 5 and a red 4, you can place this red 4 on this black 5 to unlock a new card. You first look for the aces since these are the first cards you need for the basic columns, then you look for the two, three and so on. If there are no more options on the tableau, you start with the stock pile. Enjoy!
