1. Launch the Solitaire Classic game on your mobile device.

2. Choose your preferred game mode: draw one card for an easier game or draw three cards for a more challenging experience.

3. The goal is to move all cards to the foundation piles, one for each suit, in ascending order from Ace to King.

4. Begin by tapping or dragging cards to build sequences in descending order and alternating colors on the tableau. For example, place a red 6 on a black 7.

5. When you uncover an Ace, move it to one of the foundation piles. Continue adding cards of the same suit in ascending order.

6. Use empty tableau columns to place a King, then build sequences from there.

7. Tap the stock pile to draw new cards. If you're drawing one card at a time, you can scroll through the deck more easily. Drawing three cards at a time increases difficulty.

8. Move cards strategically to uncover hidden ones and create new possible moves.

9. Continue rearranging and transferring cards between tableau and foundation until all cards are sorted by suit in the foundation piles.

10. When all foundation piles are complete from Ace to King, you win the game.
