1. Launch Freecell Solitaire Blue on your mobile device.

2. Observe the layout: eight Tableau piles, four open Foundation piles, and four Free Cells are displayed.

3. Each Tableau pile contains face-up cards from a standard 52-card deck, fully visible from the start.

4. The goal is to move all cards to the four Foundation piles, building up from Ace to King in the same suit.

5. You can only move one card at a time during the game.

6. Only the top card of each Tableau pile and any card in the Free Cells are available for movement.

7. To move a card, tap and drag it to a valid position either in a Tableau pile, a Free Cell, or onto a Foundation pile.

8. Use the four Free Cells as temporary storage to help rearrange cards and create new moves.

9. Each Free Cell can hold only one card at a time, so use them wisely.

10. Cards in the Tableau can be placed in descending order and alternating colors (e.g., red 6 on black 7).

11. You can move cards from the Free Cells back to the Tableau or to the Foundations when appropriate.

12. Keep building on the Foundations until all cards are sorted from Ace to King in each suit to win the game.
