666 blue candies may seem like a lot, but with 66 moves and four colours, it is easy to collect.
It also means that you are required to collect an average of 10 to 11 blue candies per move.
The candy bombs should not be a problem with four colours on the board, even if more spawn. One more candy bomb will spawn from the dispenser at every 6 moves.
The orders are worth 66,600 points. Hence, an additional 33,400 points is required to earn one star.
The locked candy bombs can be problematic if not removed quickly. New bombs are no threat, however, as they easily get caught in cascades.
Use special candy combinations, as usual, to collect a large number of candies in every move. Wrapped candy + colour bomb combination is the best because it reduces the number of colours on the board twice, allowing many special candies to form. After the release of Taffy Treetops, the effect of the colour bomb + wrapped combination has changed, but it is still recommended to combine a colour bomb with a blue wrapped candy since twice the number of blue candies on the board count towards the order.
Destroy as many candies as you can. Striped + wrapped combos really help with that.
Earning More Stars
The presence of four colours makes it easy to create special candies.
The order is worth 66,600 points. Hence, an additional 433,400 points for two stars and an additional 933,400 points for three stars and an additional 1,933,400 points for sugar stars have to be earned through matching of the candies.
The blockers are easy to clear with four candy colours.
66 moves and four colours make it very easy to create a colour bomb + candy bomb combinations.
More candy bombs are dispensed, giving players many opportunities to create colour bomb + candy bomb combinations.
The chocolate fountains and chocolate are not a threat in earning two and three stars.
Despite the above ratings, there is a method of earning less than three stars. It is to not create any colour bomb + candy bomb combinations. This is possible if cascades clear all the candy bombs.
This is the first level in the entire game without a Dreamworld counterpart.
It is also one of the few levels in which its level number is (implicitly) referenced by an episode or world, namely Dozy Dawn.
It is also the only level which is referenced again much later since its release. This is Dozy Dawn, of World Eight. This is because King decided to end Dreamworld at 665 due to its reputation as having many hard levels and the moon scale; 666 will never be expected to have a Dreamworld counterpart.
