Gave it a quick try, started with only 1+1+1 = 3 carriages but 5+8 = 130mph, made it to 0 speed by 1 stop remaining. It’s an interesting little gambling game, and the decision of detach vs. slow down has a neat push-your-luck statistical implication when you bring the take-lowest-but-all-6s-mean-derailing idea into account. I’m a little disappointed with the lack of any real roleplaying elements in a TTRPG jam, but I still had fun!
