When two tiles with the same number colide or when their sum is 3, they merge into one tile with same number they summed to one! Thus, 1 + 2 => 3, 3 + 3 => 6, 6 + 6 => 12 and so on. Every time a new merge occurs, the score is updated. Your best score is also shown.
After every move, a new tile is added to the board. If the board is full and no new merge can be performed, you lose.
