Yukon Freecell

In Yukon Freecell you need to build up the four foundations (left). On the tableau you can move groups of cards. A group may contain random cards, except that the starting and target cards must be built in sequence and in alternate color. For example: a group of a red J, 2, 5 and 6 can only be placed on a black Q (at the bottom card of a column). Use the free cells to temporarily park cards. Every new level is more difficult and has less free cells.
