-Play level 1-4. Cut the top, left and bottom rope at the same time. The candy will hang and Om Nom will open his mouth as it passes by.

-Playlevel 3-9. On the bottom slider, get close to the Om-Nom then move away from it ten times.

"Master Finger" achievement hints:
-Playlevel 1-7. Swipe across the screen with three fingers simultaneously and you should cut five of the ropes at once.

-Playlevel 1-18. Swipe straight up the sides of the screen with two fingers very quickly.

Note: The April 2011 update is required. Tap the candy on a string hanging out of the "o" in "Rope" at the title screen to turn it into an Easter egg. Start game play. The candy will be replaced by the Easter Egg and Omnom will wear bunny ears when close to the candy.

On certain levels you can tap a peeling bit of the background to unlock drawings. The following are the levels with these drawing in them:

1-16
2-18
3-3
3-20
4-14
5-1
5-15
6-7
7-3
7-21
8-17
9-21

On the menu screen, tap the candy once to make it turn into a doughnut, twice to turn into a cupcake and three times to make it turn back into a candy. Note: The most recent update is required to do this (and you will not be able to turn your candy into an Easter egg).

-On Level 1-7, there are six ropes. Swipe across the iPhone with three fingers at once and you should sever five of them for the Achievement.

-On 1-18, swipe two fingers straight up the sides quickly. It may take several tries but you can get the Achievement this way.
