How to play
- Deal all 52 cards face-up into 8 columns: four of seven, four of six.
- Use the 4 free cells to temporarily hold any single card.
- Build the tableau down in alternating colours.
- Build foundations up by suit, Ace to King.
- Move a sequence as a group only if you have enough free cells + empty columns to do so one card at a time.
Strategy & tips
- Plan from the goal backward - find your aces and twos, then work out a path to liberate them.
- Treat free cells as savings: every card you park is one less you can move.
- Empty columns multiply your moving capacity - protect them.
