The game takes place in a spooky atmosphere, but its focus is not on storytelling or atmosphere, but on a simple challenge: math problems.
Players take aim with a cannonball, but instead of targeting enemies or obstacles, they must score hits on math problems floating in the air, each with a different numerical value. The goal is to accurately solve the problems and earn points. The game runs seamlessly in the browser, requiring no download or registration. A high level of accuracy and quick reflexes are necessary to progress and conquer each level, making it a game that requires both mental and timing skills to master.
