One of the best strategies on level 93 is to use the stream movement for auto-matches. Also, if needs be, you can let a lemonade travel all the way from the right to the left part of the field in an instant.
Note that when you start with the level, there will be pieces with extra moves. They will help you clear the lower tiles without spending many moves.
You need to get 4 lemonades down to the bottom, but only 2 of them can be present on the field at the same time. After you collect the first two lemonades, aim for the lower tiles as it will lead to more auto-matches above, increasing your chance of getting the remaining lemonades faster.
