I haven't played Checkers for about thirty years, Lincus, but I should have been more alert, lol, nice one.
I.have no idea, I tried changing colour but no...tried placing an 'x' in centre, but no. mmnnn, we have a problem, don't we, shall we play on and see if we can keep track?
Difficult I know...though ...I think you have the lead by far now, lol
The only game I have ever played with others online a few years ago, was Scrabble...sorry, didn't forsee this problem, but enjoyed the game so far, Zy
