1. Launch the "Mate in One Move" mobile game on your device.

2. From the main menu, select a puzzle category based on the mating team, such as lone rook, two rooks, lone queen, or bishop with pawns.

3. Review the chessboard displayed on your screen. The board will show a preset position where you must find the move that results in checkmate in one move.

4. Analyze the position carefully by identifying the placement of all pieces, including the king and the supporting mating pieces.

5. Tap or click the piece you want to move using your finger or mouse, depending on your device.

6. Drag or tap to move the selected piece to the destination square you believe delivers checkmate.

7. If your move is correct, a checkmate animation or confirmation appears, and you advance to the next puzzle.

8. If your move is incorrect, the game will not advance. Reassess the position and try again.

9. Continue solving puzzles within the chosen category or return to the menu to select a different mating combination.

10. Aim to complete all puzzles across categories to master various mating patterns and improve your tactical skills.
