there's glitches somewhere. I got the "level 10 as matt" and "use a bomb" medals and I have done neither of those things. still 5/5, love this series!!!
got the third badge in 50 games. yes, the game is fair. the key is play conservatively, and maximize your points per dice ratio. if you roll 2 fives on your turn, just pick one and roll the other 5, for example. the randomness makes it seem unfair but you can easily win more than half the games, at least...
