The rules of the game.

The game board is a 4x4 matrix. Above the 2nd and 3rd column there appear the numbers: 2, 4, 8. The numbers go down (by turn: first - the left number, then - the right one). The number falls to the free bottom cell. If a cell contains the number, that is equal to the descending number, the cell value is doubled. If two neighboring vertical cells are the same, the upper is lowered to the bottom one, doubling the value of the lower. The player can:

1. Move the falling number to the left / right.

2. Rotate the whole matrix clockwise / counterclockwise.

3. Accelerate the fall of the numbers.

4. Press the pause / resume .

The game is over, when the number can not take its place in the cell (if the whole top row is filled in with the numbers, that are different from the falling number). The goal of the game is to collect the maximum number of points, the points are calculated by addition the cells.
