Plain physics makes donuts fall in unexpected ways which adds difficulty and makes you fiddle with it. I find the timing tricky but worth the effort if you like puzzles.
Clicking at the right moment is essential to clear groups of donuts, and you must aim carefully.
Controls are simple with no complicated buttons to press. The physics can be unpredictable and sometimes even perfect shots do not go as planned.
Most effective is aiming for clusters with donuts above them to make them drop. Quick reflexes and eye coordination are needed to succeed.
