Description

The game screen is very simple, at the beginning mostly gray box, the puzzle appears when the player figures will change color, the overall style is very simple.
Rules of the game is very simple, each can choose one direction to go up and down the slide, each slide once all the numbers are outside the box, the system will place a random number in the blank box appears a figure closer to the sliding direction, the same number of boxes in the close, when the collision will be adding. System gives digital box instead of two is four, players find a way Couchu "2048" figure box.

Features:

Three board sizes: 3x3, 4x4 and 5x5. The smaller the board is, the fewer cells you have, and the harder the game is.*
Three game modes: The original Power of 2, i.e. combining two tiles of the same value to produce their sum. The Power of 3, i.e. combining three consecutive tiles of the same value to produce their sum. Not surprisingly, this is pretty hard with the 3x3 board, although I found it pretty easy to get 81. 243 is a different story... And the Fibonacci sequence, i.e. combining two adjacent numbers in the sequence 2, 3, 5, 8, 13... (I omitted the two 1's in the beginning) to produce the one next to the larger value. This is pretty tricky. Try it out and you will know what I mean.
Three themes: I made a bright theme and a 'joyful' theme in addition to the original one. In case you wonder how to do themes in iOS. (There may be a better way, but themes are verbose in nature, because you have to specify all the colors, fonts, etc.)
