Description:

An addictive new take on a classic math card game! The goal of the game is deceptively simple: make the number 24 using the four given numbers and basic arithmetic -- addition, subtraction, multiplication and division.

For example, given the numbers 4, 7, 8, 8, one possible solution is: (7-8/8)*4, but it can also be solved as: 8*(4+7-8). Some problems have many solutions, others only one. Some puzzles you'll solve very quickly... but some are so devilishly difficult they'll drive you batty!

Play this game for 15 minutes a day, and you will be amazed at how much your mental math speed and pattern recognition skills will improve after only a week or two. It's a fun way to keep your mind sharp and your mental age young!

This game is also fantastic for students who are learning multiplication & division, or who need to improve their math skills, in the context of a challenging game. It also helps reinforce concepts such as order of operations and grouping.

Once you've practiced your skills in single-player mode, the real test is to challenge your friends in multi-player mode over Bluetooth. (Requires iPhone 3G/3Gs or 2nd generation iPod Touch) Experience the sheer terror of hearing your opponent frantically tapping out a solution and the unbounded joy of beating them to the answer by a tenth of a second!

For the truly competitive-minded, challenge yourself against the entire world by trying to make it onto the online leaderboard. Or for the more socially-minded, make it onto the multi-player leaderboard by playing matches against the most other players.
