Free cell is found in different interpretations, this option, for example, was called Fortress. I must say that in this case, the name was chosen correctly. But to feel it, you need to play 4 rounds (levels) in a row. It is as if you are defending a fortress from an invasion of enemies. Here, even picture cards are stylized accordingly.

The main feature here is a slight change in the conditions when moving to the next stage. At the first level, there are four free cells in which you can temporarily store cards during transfers. On the second — only 3, on the third-2. The fourth, final, level of the game provides only one free cell.

Based on the above, we can assume that the difficulty of parsing solitaire increases from the 1st to the 4th level. However, the simplified map layout rules make this increase in difficulty almost imperceptible. Judge for yourself, here you can shift any suit to any, and this applies to both one card and the whole sorted column. One thing remained unchanged in the rules: you can only put a card on a card if it is one lower in rank.
