I have created a free and open source online backgammon server

Hmmm, my antivirus tellls it's suspicious site, why?
in Virus Total detected "Criminal IP
Abusix" is it safe or?

- Tabula games are now supported. Tabula is an ancestor of backgammon, and has been played for over 1,500 years. See
- Forced moves can be played automatically. (Enable in settings)
- Advanced checker movement is now supported. (Enable in settings)
- The UI has received some TLC: the high-DPI scaling support has been overhauled and buttons now have a bevel effect to highlight their function.

A new blog post has also been published: History of Backgammon

Thanks for sharing this helpful feedback. The doubling cube is available for matches worth more than one point. Right now all of the bots available only play one point matches, you will need to create a match to play with the cube. I just recently added support for double click and single click checker movement, you can enable it in **Settings > Advanced checker movement**. Spectating matches is supported, just click "Join" while an ongoing match is selected. I have opened a new issue for adding the ability to explicitly resign a game:

Most likely this is because the IP has been used in the past for nefarious purposes. The IP is allocated from the website's host, Exoscale, and I don't really have control over that. I can say that if you are worried about security, you can play using your web browser and the game will run in a sandboxed environment.
how close is backgammon to being solved? are backgammon engines significantly better than human players?

When I was searching for this myself, I came across this article describing the history of bg computation. It also goes into the question of why solving backgammon is computationally hard from a brute-forcing pov.

I think it for probably that reason that it was among the first games where scientists tried other ways (already in the 1970's), where they trained weighted circuits very similar to what we now (wrongly imo) call artificial intelligence.

stocahastic game cannot be solved in sense checkers tic-tac-toe have been.

Best engine is stronger than human. in 24 pt match expert backgammon would be about 2-1 favorite to win. Gnu Backgammon might be bit less favorite but would be favorite.

I do doubt if engines can get better. Game is not as deep as Chess or Go and added with fact that dice plays a role even on long match. Even objectively better moves would give marginal gains anymore as most of moves are already objectively the best. Improvement since late -90's is very small.

Due to engines and popularity of poker there are no longer sites where you can play backgammon for real money.
Oh and nice looking site. Next big problem is building player base. Hope u succeed. Good luck with that,
