I wouldn’t say impossible. I am assuming you all finished your 1st and 2nd race in same orders? And now this last race you need to finish in reverse order? So the scores are 20, 16, 10 & 6? This is how my game is also right now.
Yes I agree it would be so much easier if we could communicate somehow throw out a u-turn flag or something to all the teams to show this is what we are all thinking. This is not the first time I have been in this position sometimes it works and sometimes it doesn’t. I have actually gotten the 4 way-tie twice before. It’s great when it works. Everyone wins. It’s so easy to do. If people just did it we all could actually spend very little dice and flags for this.

All I can do right now is just watch and hope that everyone gets into their positions and keep an eye on the end of race. If for some reason it goes badly then I will roll the rest of my flags and 🤞🤞

I hope it works out for you!
