Just finished level 225, took around 35 tries no exyra powers. First thing is to get a row of 5 to get a star, then attach it to a jewel that is the same as the flaming jewel on botto! Row, this has to be done early to allow enough moves to finish. Try to make moves count by taking as many chains as possible. You will need to form 4 across in appropriate spots to break chain on bottom row at least twice. Do chains at bottom first as they go you might be lucky and others as the jewels shift.
