What 2048 Fusion is
Every move slides every tile on the board in one direction, and two tiles carrying the same number combine into their double when they collide. A new tile appears only after a move that actually changed something: swiping into a wall that cannot shift or merge anything is rejected outright rather than costing you a turn. The named target is the 2048 tile, and the game ends when no direction would change the board at all.
This version adds streak scoring on top of the standard rules, so merging productively several moves in a row is worth more than the same merges spread out. A one-move undo is available on U or Z: it takes back the move you have just made, and only that one.
How it plays
Swipe up, down, left or right, or use the arrow keys or WASD. There is no timer and no penalty for thinking, so the board only changes when you decide it should. U or Z takes back your last move.
Getting better at it
Pick one corner at the start and keep your largest tile in it for the entire game. The reason is structural: a large tile can only merge with an equally large one, so if it wanders into the middle of the board it becomes an immovable obstacle sitting in the space you need.
Having chosen a corner, the direction that would pull your big tile out of it is the one to avoid. If your largest tile sits bottom left, that means swiping down and left freely, right occasionally and up rarely. Rebuilding the arrangement after it breaks costs moves, and moves cost board space.
Build your large numbers along a single edge in descending order, so that when the top two finally merge the whole row cascades. A large number stranded out of sequence in the middle occupies a cell that nothing else can merge with, which is one of the ways a board runs out of space.
Who it suits
If you like a puzzle you can play in complete silence and at your own pace, this is the one — though note that only the best score is stored, so a board you want to come back to has to be left open rather than closed. The corner discipline above is easy to state and takes sustained attention to hold for a whole board.
The one-move undo is worth using deliberately rather than saving for emergencies. Because it reaches back exactly one swipe, it lets you try a direction you are unsure about and immediately reverse it, which is a quick way to see what pulling your largest tile out of its corner actually does to the board. What it will not do is unwind a run of bad moves, so it rewards checking one decision at a time rather than swiping and hoping.
Questions
Is there a time limit?
No. The board only changes when you move, so you can take as long as you like over any decision, and you can leave the tab open mid-game.
Does a wasted swipe cost me a tile?
No. A move that cannot shift or merge anything is rejected, and no new tile appears, so probing a direction is free.
Can I undo a mistake?
You can take back the move you have just made, using U or Z. It is a one-move undo rather than a full history, so it rescues a single careless swipe but not a sequence of them.
What happens after 2048?
Reaching 2048 is the named goal, but the board does not stop you continuing to merge upward as long as you have space to work in.
