Thanks to all for your help. I did end up solving it (Wonderland Level 4, No. 7) by trial and error, but I appreciate the tips for future reference. I have never done anything like this before and thought I was too old for it--apparently not.

Seems totally random. Is there a way to get throough the maze and get the coins without just getting lucky?..
If you take the time to survey the scene, you get caught! It is hard to see the entire screen and where the bombs are.Frustrating. Any solutions?
