Terry...the last couple games I have played have pretty much been par for the course. What is it that you have done to adjust the games? I'm skeptical that you could engineer it to make it any easier or more difficult than it was previously. If you based it on percent correct for certain questions in the database, that probably won't work...the results are skewed based on times played, compunction to look answers up, familiarity of topic, etc.
On a completely different topic...is it possible to set a regular time for resetting the daily game. Again, the scores are reaching stratospheric heights. The 'game' loses its flavor once new quiz scores only marginally affect total accumulated scores.
