On any level that the red ball starts in the Building Area. Click on the wood tool (faster) or the water tool. Once done, click repeatedly in the build space, then start. Note: This is easier if you keep clicking the same location. If it lags and all the movable items are flying at you, then it is ready. If there are no moveable objects, look to see if the wood or water bars have fallen but left some still floating; then it worked. Next, press the "Stop" button, or if it does not work press the "Back" button once. Then, click the "Move" tool and move the red ball into the goal (red) zone.
