This is a project a buddy of mine and I have been working on for awhile now. We've tried to bring together some of the better features of KGS, OGS, and Kaya into one system, as well as throw in a number of features we've come to love and expect from other games and sites.
Some specific features include:
- Totally free (no premium / pay to play garbage)
- Incredibly easy signup (we don't even need your email address!)
- All games are "instant play" (no refreshing or anything)
- Support for "Live" and "Correspondence" games (there is no difference in the game play, which means you can readily play a fast paced game with a friend over multiple sittings if you wish)
- All time systems are accurate down to the millisecond for accurate competitive game play
- Five different rule sets:
- AGA
- Japanese
- Chinese
- Ing
- New Zealand
- AGA
- Five types of time control:
- Canadian Byo-Yomi
- Fischer
- Simple (X time per turn)
- Absolute (X time total)
- None (This one was the easiest to implement!)
- Canadian Byo-Yomi
- Conditional moves
- In-game analysis mode (where you can easily play out variations and mark up the board)
- Easily share game analyses
- Malkovich logs
- EGF ranking and stats
- Full game history
- Downloadable SGFs during and after play
- Advanced challenge and match making system
- Group system for clubs / organizations / friends (we're still working a bit on this one)
- Chat system
- User mail system
- Works in mobile browsers and on tablets
- (optional) Email turn notifications, as well as notifications for challenges, friend notifications, etc..) - and settings to control exactly what kind of notifications you receive (if any).
- Tournaments
- Live review mode
- Seek Graphs for quickly finding good matches
- Personal library for all of your games, sgfs, reviews, etc...
- Vacation time and auto-weekend pausing for correspondence games
- Pause controls for live games
- Dedicated forum for your group(s)
- Group ladders and rankings
- Translation to several languages
- Voice chatting in reviews and games
And we have some more features planned and in the works:
- Game history searching via pattern matching
- Mobile app (for non-email turn notifications as well as a better mobile playing experience)
- Chrome / Firefox extension for non-email turn notifications
So give it a try and tell us what you think! We'd love some feedback, both positive and negative!
