Aha - so THAT's why AppList, the 2014 app store for Symbian, hasn't had any updates or new apps for a week. The developer was busy writing a new game(!) '2048' is a popular Flash game (and rewritten for other mobile OS) and its tile value combining action is now available as a native freeware title on Symbian. See below.
2048 is a simple but really addictive game (you have been warned! ;) ). Your task sounds very simple: You have won when you have got a tile with the number 2048. To reach this move the tiles to a direction. While moving, tiles with the same value will be counted together.
Based on the original 2048 by Gabriele Cirulli.
New in the AppList store - see below for links to this if you need them; '2048', written by AppList's own developer - fancy that! 8-)
There's a choice of light or dark themes....
You'll recognise the game, hopefully. The aim is to double up the number tiles until you reach the mythical '2048'!
