64

Power of 2: 2⁶ · Reached: Mid game

The stage where managing empty cells starts to really matter.

By the time you reach 64, the board has filled up considerably. Getting into the habit of clearing out stray small tiles to free up cells becomes important.

Keep your chain anchored around the 64, and quickly merge away any 2s, 4s, or 8s that aren't part of it.
