The challenge increases with every successful journey. Players begin the game by attempting to select only the number bubbles divisible evenly by 10. Then they advance level by level, by looking for numbers divisible by 5, 2, 11, 4, 9, 3, 6, 8, 8, 7, and 12. If the player successfully navigates those waters, they’ll take on square roots, and primes.

New users can make use of the short, yet informative tutorial, which tells them all about Carl and his friend Amy, as well as showing them how to play the game. The animated tutorial offers a sample of the same entertaining graphics, animation, and sound effects that players will enjoy while playing the actual game.

“My personal goal is to increase our kids’ proficiency in recalling multiplication and division facts,” says developer Evelyn Eldridge. “These are areas that I feel hinder future success in math. I see this over and over, where kids struggle with math in later years because they cannot recognize simple math facts. ‘Carl Can Divide’ helps a child’s recall of math facts, rewarding them with entertaining gameplay, a place on the leaderboard, and virtual prize awards each time they help Carl safely make his journey.”

Each level of play in “Carl” lasts only a few minutes, making it easy for kids to play, “just one more level,” before dinner or bedtime. While the game is easy to understand, and kids can easily figure out what they have to do to succeed, it also presents a steadily increasing challenge, pushing the child to improve their math skills.
