Online game Mat Solitaire play for free invites everyone. It has fairly simple rules. The screen displays seven stacks of a different number of cards, the top of which are open. A little higher is the remaining deck and empty spaces for placing the collected combinations. There will be four of them in total, according to the number of suits. First you need to find and move aces there, and then continue the sequence: twos, threes, and so on, until the king.
