• Use all 52 cards, without jokers. Seven columns begin with one to seven cards; only each column's top card is face up.
• Foundations grow ace, 2, 3, through king, keeping each suit together.
• Columns descend by one rank and alternate red and black. A visible, correctly ordered run may move together, or a trailing part of it may move.
• Only a king or a run beginning with a king can fill an empty column. An exposed face-down card turns up automatically.
• Draw one card onto the waste. Only its top card can move. Once the stock is empty, turn the waste over without shuffling; there is no pass limit.
• In this practice variant, a foundation's top card may return to a column. Aces are not forced onto foundations.
• All 52 cards on foundations wins. A random deal is not guaranteed to be winnable. Stopping an unfinished deal is not a failing grade.

Plan ahead: Compare moves that expose hidden cards. Before filling an empty column, consider which king opens more choices. A hint shows a legal move, not a proven route to victory.

Undo and hints are practice aids. This Draw-One variant differs from the draw-three game in the Bicycle Klondike reference.
