....in the end, this change very little: I just wanted to know if I have to play to win or play to make the fun continue...because the points are really too many and I felt it was not sporty considering that many of us are just playing for fun.
My suggestions were all in that direction: if I found a chain stopper, I'll get a (limited) reward and then I can change that link to keep playing.
But this is Otto's puzzle and it's been quite a success the way it is: 30 pages and a lot of heat!
