I am still in Kwazi's Quest and have reached a screen where dragon tiles are grouped in two's across the top and the rest of the tiles are arranged in an arch underneath. I have tried to solve it again and again without success. I am quite frustrated as I've been able to solve all the others. Is there a secret? I am just about to throw in the towel since I believe this is insolvable. I'm thinking of trying to get my money back from the developers!
