The main goal of the game is solving math problems which are shown on the bars falling from above the playing field:

Answers should be entered from virtual keyboard:

If a problem solution is correct then the bar disappears, and the player gets prize points. If a problem solution is incorrect, then the bar falls down creating the construction at the bottom of the playing field.

If the construction fills all the playing field the game is over.

For 5 correctly solved problems the player gets prize points and a bomb, which breaks 1 bar with incorrectly solved problem.

For 10 correctly solved problems the player gets prize points and a super bomb, which breaks the top line of the construction with incorrectly solved problems.
