Guessing the rules of a similar game i played from observation only - hopefully some of my observation on the rules are wrong.

    1. NxN Grid
    2. Initial Block value is 2 >= init(X) <= 9
    3. When you slide the up,down, right left
       the blocks all slide as far as the can.
    4. During a slide "Like Boxes" combine and 
       add for example Z + Z = 2Z, Y+Y= 2Y, etc.
    5. With every slide there a new block added
       and placed in the Grid randomly that 
       has init(X) value. If there room on the
       Grid. 
    6. The goal is to reach a target_value of some
       number divisible by init(X) like 2048 if 
       init(X) is 2
    7. If there is not enough space for a new
       block of init(X) to be added after a 
       slide operation and the slide operation does
       not result in a running total => the target 
       

value you lose the game.
