In Smart Numbers, you have to slide the tiles up, down, to the left or to the right to make the matching numbers meld together. A match will result in a new tile with a value that is one point higher than the previous tiles. There are only 9 cells to this board, so you'll have to think carefully before you tilt the board and move the tiles. Each move will generate a new tile, so make sure the board doesn't fill up completely or your tiles will get jammed! Unlock regular mode to play the 16-cell version.
