Please try this brand new site, uploaded just a few moments ago.http://bitcoinrps.com
There are still a few things to fix up, but as it stands now the core functionality is available.
~~ Create your own RPS games and have your friends challenge you.
~~ Put money on the line and bet on the outcome.
~~ Only 1% house fee (3% is extracted from tied games which occur approximately 1/3 of the time, and no fee is charged if a game is won).
~~ Minimum bet 0.001 btc
~~ Minimum withdrawal 0.01 btc
~~ All games are hashed with SHA 256 so you can check the results.
~~ Make a help/about page
~~ Make the pages refresh more intelligently via AJAX (you currently need to refresh some parts manually)
~~ Make graphic icons for the rock, paper, scissors links instead of text.
Also in the case of no human challenges available, a bot will periodically create some. At the moment, it is just creating games worth 0.01 but it will have more variety once the site matures.
Please have fun, all feedback is very welcome.http://bitcoinrps.com
