A bug, probably.

Yes, ughaibu could write a handbook for players of all levels :-)

There are many variants of Tablut. I've just implemented the one I've found in a Slovak book of board games.

1) The throne can be used only to capture the king, not the "normal" pieces.
2) Yes, it should be considered as a draw but this site does not support a perpetual check detection yet. What you can do in such situation is to send a message to me and I will set a draw manually.

Stalemate?

sunnyday: My parents bought it 20 years ago :-)

Call it as you want :-)

Yes, you can move over. It doesn't work? What is the game ID?

The rules will be updated ASAP :-)

I'll add it to rules although I agree with Kevin :-)

Is it? That's good :-) I've got a book of more ancient games so I'll try to implement the ones which are interesting.
