Hey, Tabus Nine Computing, a company a friend and I started, just released its first app! The game is Modulus, and it's a mental math puzzle game. We haven't seen the concept anywhere else, so hopefully it'll be something new for people. The idea is that you start with a certain number, and you have to match it with a target number. This is done using six buttons that each perform a different math operation on your starting number. The amount, for example, the Add button adds to your number or how much the Divide button divides your number by is called the button's value. In different difficulty modes, you might know the value of the buttons, or you might not. It's a fun game to get into, really stretches your mental math skills! Here's the full version for $0.99, or you can get the trial/lite version if you want to try it out. In the full version, there are 120 total puzzles to play, 60 Puzzles and 60 Challenges. There's a limit on the number of moves you can make in Challenge mode. There's also Free Play mode, in which puzzles are randomly generated for your everlasting enjoyment. In the trial version, you can get to 12 of the Puzzles/Challenges, 6 in each game mode, 2 for each difficulty. Thanks! I hope you give Modulus a shot.
