I've added 3 levels of difficulty to the original 2048 game (easy | medium | hard)

http://jmaat.me/2048-Scala

Please note, this is NOT a good example of scala code :) Just something I was playing around with while on an airplane ride back from a conference in Denver. I tweaked it a bunch, but it's most likely missing a bunch of unit tests, could use refactoring, etc..

The basic idea is to make a call to a REST service which calculates the entire game board in 1 step.

For example a grid board like -

1, 2, 3, 4
1, 2, 7, 8
9, 7, 4, 5
8, 5, 4, 3

Move up, will call the service as -

[POST] 2048-Scala/move
data: {
direction: "up",
nums: [1,2,3,4,1,2,7,8,9,7,4,5,8,5,4,3] mode: "easy"
}

And return the resulting list after transposing and summing any matching sibling cell (on upwards motion), then insert a random 2 in an open spot.

returns
[2,4,3,4,,9,7,7,8,8,5,8,5,0,2,0,3]

And I use Jquery to reset the board -
2, 4, 3, 4
9, 7, 7, 8
8, 5, 8, 5
0, 2, 0, 3
