1) Allow the first dot to loop around the bottom circle twice (three times*)

2) When it starts looping the third time (4th time*), tap fast to fit at least 8 dots behind it

3) The line of dots will go around the bottom circle 4 (5*) times before going up to the top circle

4) When the line starts going to the top, tap FAST to place all remaining dot behind the last in the line

*: The level may change. When i completed it, the starting dot only went around the circle 4 times, but when i went back to review my process it has gone around 5 times

Jocie is correct
the keyword is FAST
