I'm sorry, but as i see so many dice threads about times where they were impossible and should never happen, i want to tell of my little piece of great luck
I am on the map Unification Italy Game 6882837. I had 3 on Trieste (near the top) and Pink had 11 on Krain and Karnten, then had all 1's on: Steiermark, Zagreb, Felso-Magyarorszá, Alsó-Magyarország, Tyrol and Osijek. I was only getting 3 troops, and when i cashed for 10, i had 13 to deploy, so i deployed on Trieste, giving me 16. Too lazy to hit Attack over and over, i used Auto-Attack on Krain. I advanced 14. So 16v11, i lost 1 in there. Hmm, i do the same thing on his 11 stack on Karnten. Didn't lose one. Then in the process of taking out the last of his 1's, i only lost 3. So i managed, with only 16 troops, to take out 28 in total.
Now considering to only lose 1 troop, in the process of taking out 22, and only losing 4 in taking out 28, that's pretty great, and so far, my best string of dice.
