The puzzle is simply asking for the "maximum‑score" version of the classic 2048 problem, but with only four moves allowed. In other words:
What is the largest score you can achieve in exactly 4 turns?
How does that maximum break down turn by turn (what score do you hit on the 1st, 2nd, 3rd and 4th move)?
Which board configuration gives you that final score?
In short: What is the best possible total in a four‑move game of 2048, and what sequence of moves/board state yields it? This mirrors the usual "maximum tile" question (what’s the biggest number you can create) but replaces "max tile" with "max cumulative score". The answer consists of the numeric maximum plus an explicit example (moves and board).
