I was wondering how 2048 would feel like if instead of powers of two, we can merge consequent fibonacci numbers. Turns out to be a rather interesting game that is fairly forgiving and grows very slowly. I found it difficult to come up with an overall strategy. I had a simple search algorithm that was able to achieve a score of exactly 66,666 (not joking). Getting a 987 block shouldn't be difficult.
You can take a look into the code here: https://github.com/adhami3310/987 (the simple search algorithm is inside the code as well)
