2048 Logic Puzzle I thought up this logic problem related to the 2048 game. If all 16 tiles on a 2048 board all had the value 1024, how many ways are there to get to the 2048 tile? Here is what I am talking about in an illustration:

I found a much simpler, but longer way to think about this: There are 3 ways to combine 2 tiles by going to the right, and 3 by going to the left. That means there are 6 ways to combine the tiles. So, for all the rows and columns, there are $$2 \cdot (4 \cdot 6) = 48$$ ways to get to the 2048 tile.
My question(s) are, is my logic correct? Also, is there a simpler way to approach this logical problem?
Notes
I found two Math.SE post related to 2048 logic, but they have nothing to do with my problem.

I believe you are Correct.
There are 3 lines separating rows horizontally, 4 pairs of numbers across each line, and 2 ways to combine said pairs (top-down or bottom-up), giving $2*3*4=24$ ways of making pairs.
Repeating for the columns and getting the exact same numbers, we now have $24+24 = 48$ total options for merging two numbers.
