Tri Peaks

Goal: clear all three pyramids onto the waste pile.

• Play any fully uncovered peak or base card onto the waste if it is one rank up or down from the waste's top card.
• Rank wraps: an Ace and a King are adjacent, so either can follow the other.
• Removing both cards covering a peak card flips it face-up and makes it playable.
• Draw the stock onto the waste when stuck (one pass only). No legal move with an empty stock means the game is lost.
