"Basic rules
Game Grid: The game is played on a 4x4 grid
Movement method: Swipe in any direction (up, down, left, right) to move all blocks
Merge rules:
1 + 2 = 3
Starting from 3, only the same numbers can be combined (for example: 3+3=6, 6+6=12, 12+12=24, etc.)
game mechanics
New blocks appear: after each move, a new block is generated from the side opposite the sliding direction
Next block preview: The value of the next block will be displayed at the top of the screen
Game Over: The game ends when no moves are available
Scoring system
Your score is calculated based on the value of the remaining squares on the board:
3 = 3 points
6 = 9 points
12 = 27 points
24 = 81 points
And so on (the score of each square is 3 to the nth power)
