To assemble a sequence, you will need to move the cards, shifting them to each other. The rules for doing this are elementary:
You can shift to any card, the value of which is higher by one. The suit is not important.
Columns are transferred freely, regardless of the suit cards, their components.
Not all cards are laid out on the playing field in columns. Below them is the rest of the deck of 55 cards. It is there that are missing for a particular column. But you can only open this deck once - when you turn the next card over, the previous unused one automatically becomes inaccessible until all the cards that overlap it are removed.
