Square of Number

There are three game modes:

- Power of 2 : combining two tiles of the same value to produce their sum.

- The Power of 3 : 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 more difficult.

-The fibonacci sequence : 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.

There are three board sizes: 3x3, 4x4 and 5x5.

The smaller the board is, the fewer cells you have, and the harder the game is.
