Level 42:
First dart - at 2 of the multi shots + 1 ice balloon. Also getting the 2 lowest balloons on the main section
Second dart - (multi-dart) along the top left side of the main bunch, missing out the line of iceys - its possible to get every balloon in the left section without hitting iceys here.
Third dart - Up the middle section, avoiding iceys if possible although can still sometimes complete if one is hit.
Final dart up high like a mortar and try to land on remaining non-touched iceys or remaining balloons down right hand side
