Slide any row or column until you get 4 squares of the same color in the middle 2x2 flashing area.
These squares will then be removed. Continue until all squares have been removed. Some levels may "letter" any 2 remaining squares so that you can eventually spell out the word S Q U A R E.
Manoeuvre these lettered squares in to a separate area, top middle, marked
"S Q U A R E" , which will then activate the removal of further squares.
If you can beat the Best Move Score then you will proceed to the next level.
