OK, I have all my puzzles done and the gong completed. I have a few questions.
1. I have the ancient mosaic floor cleared off, but do not have level 3 Exploration purchased yet. I thought according to the "manual" you needed that to complete that task...?
2. Now that all the jobs are done (extras, that is), is there any other way to get building points besides fixing huts?
3. Could one of the guru designers tell me on the physics of the game what the probability of that yellow rare pebble is of appearing? I watched the mosaid section of the game exclusively during the entire time it was being cleared and it never appeared (well over 10 hours).
