Rumble Ball 4, which is available on www.flash-games.net, is a challenging puzzle game that your objective is to collect all of the bonuses to step into the next level. The items will be arranged into different shapes. To hit the ball, click and drag around the ball to adjust the power and angle of your shot, then release the mouse to send out the ball. The longer you hold the left button, the more power it will be, and the power bar is located at the bottom of the screen. Beware; when the ball hit the square box, the ball will be rebounded. As you progress, the levels will get harder. You will gain more points when hitting more than two boxes at once. What’s more, you can skip the level and select any one as you like. At the bottom of the game screen shows your score and the left items. Go ahead and try to score maximum points. Good luck!
