Should you try to be fast or should you try to be accurate?
The scoring system rewards accuracy much more highly than speed. Being fast will only double your score; being accurate will multiply your score many times. Your score is worked out mathematically, which makes it both measurable and fair. The points, accuracy and time bonuses are calculated using formulae based on the number of colours and layers of each puzzle.
