7749

Why "7749" ?

Why first number is 7 -> this is a creative new style brick game of 7 ways.
Why second number is 7 ->there are 7 color block holders that you can control in game.
Why third number is 4 ->each color block holds has max 4 cells.
Why the last number is 9 -> there are total 9 block holders in the game .

You should piece 4 cells for one of the block holders to keep the energy bar alive.
If losing cells , the energy bar gets shorter so does the game time passing.
When the energy bar is gone -> game over.
