Hundred and twenty is a fast paced mathematical puzzle game consisting of multiple game modes to sharpen one's wits and hone one's math skills. The Apple Watch extension of hundred and twenty is included in version 1.2 and higher. Regular mode presents the user with a set of randomized numbers ranging from 1 to 40 in which the user must use addition, subtraction, multiplication and division to make their number equal to 120. Puzzle mode presents a computer generated puzzle set of 5 numbers in which the user must combine 2 or more numbers in conjunction with operators to make their number equal to 120. To make the game more intense, time challenge mode may be turned on to make the user race to find a solution before time runs out. A difficulty slider is available so even the youngest of users will enjoy building their proficiency in math. Leaderboard scoring in Game Center is supported to add a level of friendly competition amongst users. Hundred and twenty displays an artistic modern user interface along with a high energy original soundtrack to add to the user experience.

The Apple Watch extension allows the user to play the hundred and twenty puzzle mode straight from their Apple Watch. High scores and settings are synced between the two devices allowing for seamless transition from one to the other.

Fun and challenging

I like to play mostly in puzzle mode. Sometimes the solution is easy to see but other times it's quite challenging involving 4 or all 5 numbers in combinations that aren't immediately obvious. Keeps you thinking!

Totally AWESOME!!!


I really like this game because it's fun and it can help you with math. I am not the best at math so playing a game that's fun and can help me is the best. I would definitely recommend this game to people of all ages.
