A familiar game, a quick refresher.

  1. Build the four foundations. Place aces in the top-right spaces, then build up to kings in the same suit.
  2. Alternate colors on the table. Place a red 6 on a black 7, for example. You can move an entire face-up sequence.
  3. Make room for kings. Only a king, or a sequence starting with one, can move to an empty column.
  4. Turn over a new card. Click the face-down deck. When it runs out, click again to recycle. You can go through it as often as you like.

Keyboard: Tab to a card and press Enter to select it. Tab to the destination and press Enter again. Escape clears your selection. You can also drag cards.

Deals are random; some cannot be won. Hints suggest legal moves, not a guaranteed solution.
