It's a very simple game, where you have blocks falling from the top of the screen into the bottom where they collect in a pile.
Each block has a number and you need to select a combination of numbers whose sum is a given Target(Top of the screen ,in front of the balloons).
You have 100 Levels to finish:
50 are score based: given a period of time you need to reach the score target. And the others are survival levels, where no score is required, You just need to survive during a blocks bombing.
You have also the King Mode (crown icon) : Play endlessly to break your high score!
Thats not all!
In the game you have boosters, game missions and daily booster wheel.
