Reverse 2048 is 2048 played backwards. New tiles arrive as 2048 (90% of the time) or 1024, and when two matching tiles collide they merge into one tile worth half as much: two 2048s make a 1024, two 1024s make a 512, and so on. Make a 1 and you win.
How it compares with 2048 reverse versions you may know
The board and the moves are exactly those of the classic 2048 game; only the direction of the numbers flips. You need eleven halvings to get from 2048 to 1, the same number of doublings it takes to get from 2 to 2048, so the game is the same length and the same difficulty in disguise. Your score adds the value of every tile you make, so it grows much more slowly than usual.
Tips for reaching 1
Everything from how to win 2048 still applies, turned upside down: keep your smallest tile in a corner and line up the next smallest beside it. The big 2048s that keep arriving play the part of the stray 2s in the original, so merge them early.
Questions
What is the goal of Reverse 2048?
To make a tile worth 1, by halving 2048 eleven times.
Why does the score go up so slowly?
Each merge adds the value of the new, smaller tile. Making a 1024 adds 1,024 points, but making a 2 adds only 2.
Is Reverse 2048 harder than normal 2048?
No, it is the same puzzle mirrored. It just feels harder at first because the numbers shrink.
