In a row. - slide Right -> shift Right - slide Left -> shift Left - slide Down -> fall faster - flick under -> Block fast fast drop. You can block until all of the stick shift. connect 3 or more blocks of the same color,Block disappears & Get Score!! When "Chain" a lot, you get a high score. When blocks disappear a lot together, you get a high score. Operation is "Right shift","Left shift" only. very simple. but, adding "When to shift?" is difficult to puzzle. Game Level will increase , if you continue to remove the block. Game will be more difficult as the level goes up. - Features a.
