Smart Ring - Make It Find the Right Way

You can't control the blue colored smart ring, but you can let it decide which way to go. Before reaching the pink circle, you must make sure that the smart ring grabs all bright objects placed in game arena. Drop obstacles where necessary to achieve this. It will not pass through the places where obstacles are left. Drag your finger on the screen to drop obstacles or click once to drop one obstacle at a time. So the most important point of the game is to drop these obstacles in the right place. But remember! You have limited resources.
