The moon scale is fairly unstable because of the amount of space to cascade. Also, the candies do not start from rest. However, the presence of all six candy colours also helps this not to occur as often as the player thinks.
If the jelly fish clears jellies in the middle part of the board, it will be hard to clear the rest of the jellies in the corners.
The jellies are worth 30,000 points, which is more than the one star target score.
Watch the moon scale as it may be easy for Odus to fall.
Alternatively, leave three to five single jellies at the centre of the board. Next, create a colour bomb and position next to a jelly fish. Finally, activate the colour bomb + jelly fish combination. Since the jelly fishes are programmed to attack the centre jellies, they will produce nine more jelly fish which in turn will remove one layer of jelly from all the remaining jellies including those at the corners. This method is harder to do but has the advantage of not worrying whether if there is a double jelly at the corners but with only one jelly fish left. This is because there will only be single jellies left at the corners.
