You should be aware that Pebble It is still in development, so you will likely see some changes in the near future (where "near future" probably means from now until fall 2009). You may also experience crashes, etc. If you experience any problems or have any suggestions, please forward them to the Principal Investigator (See Credits page for a link to his website).

You should also be aware that puzzles, scores, user accounts, etc. may be deleted from time to time. Thus, do not be surprised if you come back in a week or month and find you can no longer log in. If this happens, just create a new account.

As the project develops it will become more stable and accounts and puzzles will eventually remain intact. Eventually players will be ranked according to how they are doing on the puzzles, and there will be at least three different types of puzzles that provide different challenges, each of which helps solve different problems related to graph pebbling. We will provide additional details on the website as the project progresses, so check back from time to time.

Now that we have that stuff out of the way, please go to the Instructions page to learn how to play, find out more about the game and what is behind it on the About page, or just click play at the top of the page and try it out!
