Eat all ghosts four times within a stage!
I drew a diagram of a pattern that works... this works 9 times out for 10 to get your first four in a row (easy way to get the All Ghosts achievement).
NOTE: This method works BEST in Level 1.
1. Using the blue lines and arrows, Immediately from the start head toward your first point (the blue circle) and WAIT there... youll see a red ghost and blue ghost eventualy come at you (red 1 and 2) just like that...
2. You have to wait til the last split second (right before youre about to get hit by ghost 1) to move down and follow the path... the blue ghost should be right on your tail...
3. Immediately go for the power pellet and go back down... the ghosts should be perfectly lined up with the exception of one who will be floating across the bottom... just follow the path and you will have your first four.
Now, here's the method i used to get the rest... make sure your lives are set to 5.
4. you should die and follow steps 1 and 2...
5. now go right past where the pellet originally was and follow the green arrow to the middle right section of the screen that allows you to pass through and come out the other side...
6. Go back and forth (evading the SIGHT of the ghosts) until you see a perfect chance to go for the next pellet... just wait until theyre all close together and make a dash for it.
7. Die and repeat steps 4 - 5.
