Game Rules:

1. Rule 1: The primary objective is to combine two identical tiles or numbers by sliding them together. When two tiles with the same number touch, they merge into a single tile with a higher number.
2. Rule 2: Each successful merge upgrades the tile's number and increases your overall score. Plan your moves to create larger numbers and maximize your points.
3. Rule 3: The game board is a grid where tiles can move up, down, left, or right. Swiping the screen or using the keyboard controls will shift all movable tiles in that direction until they hit an obstacle or another tile.
4. Rule 4: The game ends when the board is completely filled with tiles, and there are no valid moves left to merge any two identical tiles. Keep a close eye on the board's empty spaces and plan ahead to avoid getting stuck.
5. Rule 5: Try to keep the highest numbered tile in a corner or along an edge to prevent it from getting trapped in the middle of the board, making it harder to merge with other tiles.

Controls:

1. Action: Touch or mouse: Swipe the game screen (up, down, left, or right) to move all the tiles in that direction.
2. Action: Keyboard: Press the W, A, S, and D keys to move the tiles up, left, down, and right, respectively.
3. Action: Some versions of the game might allow using arrow keys for movement instead of W, A, S, D.

FAQ:

1. Q: What happens if I can't merge any more tiles?

If the board is full and there are no valid moves left to combine tiles, the game ends. You can then view your final score and start a new game.

2. Q: Is there a time limit in Merge Numbers?

Generally, Merge Numbers is a relaxing puzzle game without a strict time limit. You can take your time to plan your moves and aim for the highest score possible.

3. Q: Can I undo a move if I make a mistake?

Most basic versions of Merge Numbers don't offer an undo feature. However, some advanced or customized versions might include an "Undo" button, allowing you to revert your last move if needed.
