Bots …
… are operated by users, not the site. Maybe someone is planning to introduce a bot, maybe not. Difficult to predict.
A list of bots…
… can be found here. It looks like not all of them are rank restricted.
Sidenote on the XY problem
You just want to play? Or play against a bot?
Whether you should play against bots as a beginner
This question was raised recently in this thread.
Find a game against a human player
Ask for a teaching game. Write that as the game name if you post a challenge. You can also ask on the forum, as so many others did before. Teaching games against humans are a good way to learn, especially when there is a review afterwards. You can also join one of the study groups. Let me shamelessly refer you to this “shameless” post.
You still can, just make the match unranked. At the moment it is currently impossible to play ranked matches with more than 9 stones difference and I do not think this will be changed any time soon.
On computers finding a weak bot is indeed almost impossible. However you can find bots with very low settings for android, if you ever wanted to practice in bus or something :). Search for “crazy stone light” or “go free”. The ranks are a little misrepresented there, sayin 15k on a level that might suit a beginner just fine I think.
And feel free to send me a challenge as well if you ever feel like training with a human
Master Mantis does play at 25k level, you just can’t play ranked games against it due to the rank inflation it gains by winning against the new 13k accounts owned by honest-to-god 30k players.
If you wish to play a bot that’s even worse, try IdiotBot on KGS.
I don’tquite see the value in playing against something that makes 100% random moves though. You’d learn and improve quicker by memorizing pro games. The Alphago Lee approach.
If that is really the case, then some ddk-players, 16k+ say, should play MasterMantis, just so that its rank gets deflated again.
I might try that this weekend.
