Fill corners with low numbers. Be patient and play strategically by filling the corners with numbers of similar low values. Leave as much space as possible to be open in the middle. Although the level will fill quickly because you are not making a lot of many matches, after a few moves you may be able to move tiles around. Create matches where desired open new spaces for other cells to move through. When the level gets mostly filled, begin making matches towards the corners while planning ahead to open routes for your numbers. You must make the matches exactly where they belong and where they should be to open space for more matches in a row. When at least four tiles at matched, the level will not get new tiles. Use those types of matches to empty the level as much as possible. Match four cells with 128 or 256 value to remove them from the level. Additionally, matching five of such cells will give you the maximum value.
