Interchange

Interchange

• 104 physical cards. Columns begin with 7, 7, 7, 7, 7, 7, 7 cards. Alternating cards, starting with the second, are face down. One stock card starts face up on waste; the rest form stock.
• Build down by suit, without rank wrapping. Only descending same-suit sequences move together.
• Only a King or King-led legal group fills an empty column.
• Draw one to waste. Only the waste top is playable. No redeal. Recycling preserves original draw order.
• Build 8 suit foundations Ace to King, one card at a time. Select a foundation top with no card selected to return it to a legal column.
