1. Launch the "Classic Solitaire: Time and Score" app on your mobile device.

2. The game starts with a shuffled deck of 52 cards. Cards are dealt into seven tableau columns with increasing numbers from left to right—first column has one card, second has two, and so on. Only the top card in each column is face-up.

3. The objective is to move all cards to the four foundation piles located in the upper-right corner, sorted by suit from Ace to King.

4. Below the foundation piles is the stockpile. Tap the stockpile to draw cards into the waste pile, using them to help organize the tableau.

5. You can move cards within the tableau by arranging them in descending order and alternating colors—for example, placing a red 6 on a black 7.

6. Only Kings can be moved into empty tableau columns.

7. As you reveal face-down cards in the tableau, flip them over and continue building sequences.

8. Double-tap or drag cards to move them to the foundation piles when appropriate.

9. The game is timed, and your score increases based on correct moves and speed.

10. Try to complete the game quickly and accurately to achieve your highest possible score.
