Gardenscapes-Level 37 is clear and simple in structure. The only thing that makes it difficult to beat is a large number of acorns on the field that all need to be collected.
In order to succeed you should make matches that will at the same time destroy the acorns and reveal the gnomes, so make all of your matches count unless you want to make a combination for a power-up. Start from the bottom of the field, get rid of about half the acorns to let the other half fall down so that you could make matches on the top. The result will be a large number of automatches and power-ups that will help you with the final stage – collecting the remaining gnomes. After all the gnomes are collected, there shouldn’t be any acorns left on the field.
