The clock begins when speedrun mode starts and locks the instant the 2048 tile appears. You do not need to extend the run for more points, so each choice should lead toward the next useful merge.
The timer starts with the mode.
Creating 2048 locks the result.
Undo never rewinds the clock.
02
Fast runs still need structure
Rapid input without a plan creates recovery work. Set a corner and a main movement axis early, then look for rows where multiple pairs can combine in one move.
Choose the large-tile corner early.
Look for multi-merge rows.
Use moves that create open cells instead of repeated blocked inputs.
03
Remove the habits that lose time
Long pauses lose time, but blind repeated swipes can lose much more. Decide on the next move while tiles are settling, and use undo only to rebuild a broken plan, never to try to recover elapsed time.
Check the value chain after each move.
Confirm a direction is open before repeating it.
Choose a fresh cleanup direction after undoing.
