Twofold: 2048 Merge Puzzle

2048 meets tube sort. Stack number tiles in tubes, drop a tile on its twin to merge it, and fold the whole board into one single tile. A calm, offline number puzzle that makes you think.

HOW TO PLAY
Every tile is a power of two. Lift the top tile of a tube and drop it onto a matching tile: 2 and 2 merge into 4, 4 and 4 into 8, all the way up to 2048. If the tile underneath matches too, the merge keeps going in one satisfying chain. A tile can also rest in any tube with room, but a full tube takes nothing. Sort, stack, merge, repeat, until one tile is left on the board. That is a clear.

EASY TO LEARN, HARD TO MASTER
One rule is all you need to start. Then the tubes get deeper, the numbers get bigger and one careless drop buries the tile you needed. Every level has a shortest solution: beat par and take all three stars, then come back and shave off a move.

A PURE LOGIC PUZZLE
No hidden tiles, no random drops, no timer, no luck. The whole board is in front of you, and every level is checked by a solver, so every board can be cleared. Plan a few moves ahead and the big merges line up on their own. A brain game for players who like to think, not tap fast.

100+ LEVELS
Two-tube warm-ups grow into crowded boards where every move counts, all the way to a final 2048 tile.

BOOSTERS WHEN YOU ARE STUCK
• Undo takes back a move
• Hint shows the next move on a shortest solution
• Extra Tube adds an empty tube when the board gets tight
• Restart wipes the board and starts fresh
