Drag the wrecking ball on its chain, build momentum, and let it crash through the buildings on either side.
A wrecking ball hangs from a crane at the top of the screen. Stacks of building blocks stand on the ground to the left and right.
Touch and drag anywhere: the ball jumps to the direction of your finger and follows it, always at the end of its chain. While you hold it, it cannot break anything. The speed it has when you let go comes from how fast your finger was moving at that moment — fling it, or simply lift it high to one side and let gravity do the work.
Release your finger and the ball swings freely. A swinging ball that is moving fast enough knocks one hit off every block it touches; a slow touch does nothing. Plain blocks break on one hit, blocks with a white dot need two. Each block can be hit only once per release, so after the ball has swept through, grab it and let go again. When a lower block breaks, the ones above drop down into the ball's path.
Every destroyed block scores one point. When both stacks are gone, two new ones appear. You have 60 seconds, and the clock starts with your first touch.
Goal: highest score.
Height is free speed. A ball let go from high up at the side reaches the bottom of its arc fast enough to break blocks on both sides in one pass, with no flick needed. A fast flick in the direction of the swing adds more, but a flick against it, or a slow drag, can leave the ball too slow to do any damage.
Think in releases, not swings. Each block takes at most one hit per release, so once the ball has swept through both stacks, extra swings do nothing. Grab it again right away — the moment you touch, the ball jumps to your finger, so you can lift it back up to the side within a fraction of a second.
Clear the bottom first. Broken blocks let the ones above fall into the lowest part of the arc, where the ball is fastest, so one stack melts quickly once its bottom blocks go. A dotted block needs two separate releases, so if one is sitting at the bottom of a stack, it is worth an extra quick lift and drop to get the column moving again.
