How does one decide who flips the coin. Whoever flips is at a disadvantage since the coin is flipped on a tie of die roles. The outcomes of the flip are another die roll or the other player goes. Also quite strange that you can't quit until there are 3 pieces per player left. How is that supposed to be enforced? Domestic violence or something?
