I understand there is no age restriction, but my opponent is claiming to be 9. That is too young to play this adult game. My game bugged out & I can't even open it. We were only half way throught the game. I started a 2nd game & oppenent accepted the game, but refuses to acknowledge that I can claim win if I win 2nd game. We are just starting the game. The child doesn't understand the issue & insists he is right. Honestly, I don't even want to continue the game, but I will. I expect if I win then I will get the correct credit. I don't even know the score for our bugged game. It was close. UPDATE..... THE PARENT CONTACTED ME. WE HAVE RESOLVED IT.
