Goal: move all 52 cards onto the four foundations, one per suit, in order from Ace up to King.
\nLayout and addressing. The seven tableau piles are t1 to t7 (left to right). Each pile starts with some face-down cards (shown as [##]) under one face-up card. The foundations are f1 ♠, f2 ♥, f3 ♦ and f4 ♣. The stock is the face-down draw pile and the waste is where drawn cards land; only the top waste card can be played. In the text board each tableau pile is listed from bottom to top, so the last card in a row is the top card.
Moves. On the tableau, a card goes on a card one rank higher of the opposite color (a red 7 on a black 8). You can move a face-up run of cards together: move t6 t1 3 moves the top 3 cards of t6 onto t1. If you leave out the count, the game finds the run that fits. Only a King (or a run starting with a King) can go into an empty pile. Foundations take one card at a time in suit order; use f as the destination and the right foundation is picked. You can also take the top card of a foundation back to the tableau. When a face-down tableau card becomes the top of its pile, it is turned over automatically. You can name a face-up card instead of a pile as the source, e.g. move 7h t3 (use s, h, d, c or ♠ ♥ ♦ ♣, and 10 or t for tens).
Stock. draw turns over 1 card (draw 1) or 3 cards (draw 3, where only the last one drawn is playable). When the stock is empty, recycle turns the waste back into the stock in the same order. Passes are unlimited, but recycling costs points: 100 per recycle in draw 1; in draw 3 the first two recycles (three passes) are free and each later one costs 20.
Help. moves lists every legal move with its effect. auto moves every card that is safe to put on a foundation (Aces, 2s, and cards whose opposite-color foundations are high enough that nothing could still need them); once all cards are face-up and the stock is empty, auto finishes the game. The board warns you when no productive move is left (nothing can reach a foundation, no face-down card can be revealed, and no stock card can be played); then you can resign.
Scoring (Windows standard style): +10 for each card moved to a foundation, +5 for each waste card moved to the tableau, +5 for each face-down card revealed, -15 for moving a card off a foundation, and the recycle penalties above. Winning adds a bonus of 500 plus 2 points for each action under 200 (draws, recycles and card moves count; moves and select don't). In draw 3 the total is multiplied by 1.5. The final score is never below 0. The game ends when all cards are on the foundations, or when you resign (you keep your points but get no win bonus).
