Wooga recommends you play their regular scenes from left-to-right instead of randomly in order to maximize..

Yes, it's true. For example, when filling the fifth star, tapping the first 8 objects in the order they are written from left to right will give you the maximum base score of 454,000. Try switch any of those first 8 objects, and you will not be able to achieve that maximum.

Your total score is the highest when you reach the fifth star and is the sum of 4 scores: 1. Base score is 454,000 maximum, for tapping the first 8 objects in order, as written left to right. 2. Accuracy score is 40,000 max for not mis-tapping. 3. Hint score is 40,000 max for not using any hints. 4. Speed score, of course, depends on your speed. "Perfect" rating is achieved by finding all objects before the bonus bar at the top runs down at any time, without hints or misses, and does not reflect order or speed, other than no lapse of the bonus bar. Highest scores are achieved by having “perfect” rating, plus speed and order (although some player’s speed can overcome the deficiency of not tapping in order).
