Finally i have Windows 8.1 app in the Windows app store. I build this app with the help of my friend. We have developed a number game to click the numbers in regular order during Windows 8.1 DevCamp. MIC Nepal had organized Windows 8.1 App DevCamp. This App is written in Visual C#. This app was selected as one of the best app in that DevCamp.
The numbers are in random order and there is a time limit for you to complete the Challenge.
Touch In Order – Visit the App page.
Update (10 June, 2014): I have developed similar game for Android. You can get it in Google Play Store Touch in Order.
