Spider Freecell

Twenty minutes sit on the clock. In Spider Freecell, four foundation piles wait in the upper right, and the full deck has to reach them in suit order from Ace through King.

How to play?

Move the exposed card from one column onto a card ranked one point higher, with suit not affecting that placement. Across the tableau, shift a run only when the sequence alternates colors. Use the four free cells in the upper left as temporary parking spots for single cards. Build space carefully, then transfer cards onto the foundations until all four piles are complete before time runs out.
