A good move starts with an idea.

Retry one fixed board in eleven and five presses, inspect all 32 top-row trials, and prove which solution is shortest.
02Number MergeNumber Merge: why the score differs from the tile total.
Follow four checked moves to separate merge points, the sum of the board, and the largest tile.
03Sum SelectSum Select: choose what to leave out.
Turn a large target into a smaller omission sum, check six worked answers, and distinguish fewer omissions from fewer selected tiles.
Take your time.
That’s part of the fun.
