Each chapter covers a certain level of math skills and difficulty level to guide users to learn math through playing. Each level is designed based on the CCSS curriculum.

The storyline takes place on the peaceful planet of Maths, which was attacked by a group of dark monsters who try to turn the planet into a dark kingdom. To defend their home, game players, who are the residents of the planet, get help from some symbol fairies who have the power to turn dark monsters into colorful balls of numbers.

The rule of the game is simple: by dragging two balls together and get a result of a targeted amount, the enemy will be defeated. Before each game, players will see their "enemy" (target number) and tips to make the target number. When players struggle to make the targeted number, they get a hint during the game. After each game, players can review the equations they've used in the game. This feature will help them monitor their progress in learning each skill.

At Ahaaa Math, we believe maths is perfected through decent concept learning and enough practices.
