Last Saturday (2/10/2010), through 7-jar competition, my team solved 7 riddles to discover treasures in Amman. But we made a costly mistake that prevented us from winning. Although there were some organizational problems, I had fun and I do recommend 7-jar.
The competition is very challenging: physically and mentally. The riddles are not specific and not precise which is frustrating and challenging at the same time. You end up visiting multiple places to reach the correct place (treasure). We used many public transportation means, ran several kilometers, walked more than 10 kilometers, climbed long stairs, and drank many bottles of water. We have visited places we have never been before.
Good experience in Amman, its attractions, and its history is vital to solve the riddles.
I am looking forward for the next one.
