Basic Rules
Game Grid: The game is played on a 4x4 grid.
Movement: Slide in any direction (up, down, left, right) to move all blocks.
Merge Rules:
1 + 2 = 3
Starting from 3, only blocks with the same number can be merged (e.g., 3+3=6, 6+6=12, 12+12=24, etc.)
Game Mechanics
New Block Appearance: After each move, a new block is generated from the opposite side of the slide direction.
Next Block Preview: The value of the next block is displayed at the top of the screen.
Game End: The game ends when there are no more moves available.
Scoring System
Your score is calculated based on the values of the remaining blocks on the board:
3 = 3 points
6 = 9 points
12 = 27 points
24 = 81 points
And so on (each block is worth 3 to the power of n)
