There is NO swap button for Havannah 10x10. Under the Rules there should be a swap option for the second player.

How do we contact Admin to correct this. Please advise asap.

It is according to author's rules. No swap rule for size 9 and bigger.

Thanks for the quick response.

Christian once said that he has no opposition to swap for size 10 hex. http://littlegolem.net/jsp/forum/topic2.jsp?forum=50&topic=583
