Thirteen columns contain 91 cards, with 78 hidden at the start. The other 65 form a draw-three stock, giving this three-deck Klondike a large waste to navigate.
The top waste card controls access
Only the exposed card of each draw is playable. Removing it reveals the card beneath and changes the grouping on later passes. Recycling the stock is unlimited. Build columns down in alternating colors; ordered runs can travel together, and empty columns accept kings or king-led runs.
Choose between three copies
All 156 cards must reach twelve suited ace-to-king foundations. When identical cards can make the same move, compare what each would uncover. Releasing a hidden card usually gives you more information than moving a duplicate that only lengthens an existing run.
