How to play
Complete all eight thirteen-card indexed foundations, ending every rank cycle with its original reserve card.
- Eight tableau piles and eight matching reserves receive one card each, eight foundations begin empty, and the remaining eighty-eight cards stay in stock for row deals.
- Deal one stock card to each tableau. Tableau pile number N may feed only foundation N, whose base is one rank above that pile's reserved card and then rises with wrap regardless of suit. The reserved card may move only after its foundation has accumulated the preceding twelve cards.
- Complete all eight thirteen-card indexed foundations, ending every rank cycle with its original reserve card.
Strategy tips
- Track the next rank for all eight foundations before dealing a row, and clear exposed tableau cards promptly so later row cards do not cover several useful successors.
- A correct rank on the wrong tableau index cannot move to another foundation, and spending the reserve card before twelve predecessors is not permitted.
- When stock is nearly empty, finish each twelve-card prefix in index order so its waiting reserve card can close the cycle immediately.
