It wasn’t on Global but for the original 1998 (I think) computer Axis & Allies game. I invaded Japan with a big army supported by 10 air units .
During the AA roll the computer got 10 out of 10 ones… destroying my whole airforce. Ha… and people say computers never cheat. Anyway, I took the CD rom out of the drive, threw it across the room, and took a week off from the game.
Anyway, I think the odds of getting such a result for the computer enemy was 1 out of 60,000,000 or something.
