Your mission is to line the boxes up vertically (at least 3 boxes of 1 color). Use the arrow keys to move left and right. Use space to take boxes and extras (bomb, brush) or to use/throw them. Height-bar moves down after the dropper did 1 turn and resets to left position. Raise the bar by removing boxes for 3 times. Be fast at removing the boxes to get a higher score (watch bonusmeter). Brush will change the colour of the whole column into the colour of its lowest box.
