Level 1218 is the thirteenth level in Marmalade Moon and the 572nd jelly level. To pass this level, you must clear 25 single jelly squares in 25 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
You can win this level instantly if you combine colour bomb + colour bomb, so in theory, you can win in two moves.
In practice it might be a long wait for the colour bomb + colour bomb combination, but not such a long wait for other combinations, especially wrapped + striped candy, that open up the board and start to get that frog fed.
You will probably only get one frogtastic so use it wisely; the square diagonally down and right from the top left square is the place. That eliminates all nine jellies that cannot be reached by specials from the main board.
Once you have done that essential frogtastic, ignore the frog. If by chance you get to feed up the frog a second time, that is a bonus.
Just focus on combinations such as wrapped + striped candy and colour bomb + striped candy to close you out.
It is quite hard, but quite good fun too. Good mixture of luck, thought and planning challenge.
