A derivative of 144, which is a deriative of 2048, which is a derivative of Threes.
In this version of the game, the board is now 5 by 5 instead of 4 by 4. Also, any number of tiles in a row will merge into one, not just two. You are trying to create 180, which is only possible by merging 3 in a row a few times, which is considerably harder to do on purpose than just two.
