Mini-Project: Android App – Make The Number!

Ok, while I’m at uni, working on my CNC is a bit tricky. I have limited time, space and tools and only a small window of time per day in which it is socially acceptable to use drills. So I decided to try a software project.

A few months ago while watching Countdown on TV, I realised that I wanted to play the maths round in my free time. However, perusing the Google Play Store I was surprised to find  only one free app offering this game. Even this had limitations however, after 200 levels the game was over. So I decided to make my own.

The aim of the game is to take 6 randomly generated numbers and, using addition, division, multiplication and division, produce a given number. This must be done as many times as possible in 2 minutes.

My app would also feature: A leader board, an “infinite mode” (no time limit), and a feature to save sums so that you can come back and solve them later.

Luckily, Google supply their own Game api which gives access to leaderboard hosting and manipulation. This proved to be the trickiest bit of the app. It was a very fiddly process involving specifying “app signing keys”, although once you’ve done it once, it wouldn’t take long to do it again.

Anyway, here is the app!
