Number Room.

A clean little 2048 game. Merge matching numbers, keep a route open, and see what comes next.

Score: 0

The rules in one minute

Move the entire board left, right, up or down. Equal adjacent tiles merge once per move, adding their new value to your score. After a move that changes the board, a new 2 or 4 appears in an empty cell. An ineffective move adds no tile. Reach 2048, then keep going if you like.

One move, one merge per tile

SnapSong rules example before the random new tile appears. The two new 4s do not merge again in the same move. This move adds 8 points.

A practical first strategy

Pick a corner for your highest tile. Build a descending line along that edge, and avoid moving the high tile away unless there is a clear reason. Keeping empty cells is often more useful than taking the first available merge. Random tiles mean that no move sequence guarantees a win.
