All sugar keys have to be used for the ingredients dropping. This can be annoying especially with 12 moves.
The keys are relatively hard to reach and are almost required to bring down the middle ingredient unless you can manage to switch it into one of the end columns, which isn't too easy.
Three of the keys are locked and require some work to unlock.
You have four colours, however. Getting the keys and bringing down the ingredients will be easier with four colours when you have a lot of cascades.
The ingredients are worth 30,000 points, which is equal to the one star target score.
Every move counts on this level. The best combination is colour bomb + wrapped, but make sure that the wrapped candy is one of the same candy colours of the keys. Although you are still left with the last ingredient, it is much easier to get them down.
Element Spawn Notes
If there are fewer than 5 sugar keys on screen, then the board spawns up to 5 when possible.
↑3 ingredients × 10,000 points per ingredient = 30,000 points
