Press the left mouse or finger (touchscreen) button to start the match. Now move the mouse on identical adjacent alphabets (Horizontally, vertically or diagonally). Select at least 3 or more alphabets. Release the mouse to let the match happen. This will merge the selected alphabet letters and creates a one new letter which is the next to the selected. For example if you select 3 or more than 3 blocks labelled with 'A', the resulting letter will be the B.
