Mastermath

Mastermath was an iOS app I built back in 2014.

The Pitch

Mastermath is a number puzzle game you can solve by using your deduction skills and some basic math.

Anyone can solve the Mastermath, but few can solve it in a short amount of time! Are you one of the few? Try it out!

The Mastermath is a 3x3 grid with number ranging from 0 to 3 in each tile. Your goal is to find which number goes in each tile in the shortest amount of time possible. Everytime you validate your grid, you will be told if the sum of each row, column and diagonal line is correct or not. Here's the catch: you have a maximum of 25 attempts to solve the Mastermath!

Another game mode is also available: BEAT THE CLOCK! In this mode, you are told which number goes in the center tile and you aren't restricted to a set number of attempts. But hurry! You only have 30 seconds to solve the Mastermath and Beat the clock!

A few pictures...

Where is it now?

Like the other iOS applications I have made, Mastermath is no longer available because I didn't renew my Apple Developer license, and I didn't update the app for newer versions of iOS.

However, back in 2022, I built a very-rugged web prototype of the game, so here it is in all its glory for your enjoyment:
