Spider Solitaire is one of the most popular online solitaire variations. Game time is not limited, but the accounting is conducted. A nice feature of this Spider Solitaire variant is an "Undo" button, which allows you to cancel the last move, although the counter of moves does not decrease. It is possible to get a hint by clicking the "Hint" button.
The game has three variants for choice. The first assumes the presence of only one suit - spades. Of course, this is the easiest version of the game. The second option requires the presence of two suits - spades and hearts. This complicates the task, because you need to put the sequence by suit. Although, it is not so difficult to "attach" 8 spades to 9 hearts, but in the end it is necessary to obtain a sequence in descending order exactly the one suit, which is discarded then. And at the end the third option, the most difficult one; that one in the right corner which suggests the presence of all four suits. Once you have collected the entire sequence from King to Deuce and Ace, the sequence is discarded. Good luck!
