How to Beat Kris KringROLL in Yahtzee with Buddies

How do you beat Kris KringRoll in Yahtzee with Buddies? As you might guess, KringRoll is the last character to beat in the Dice Pole Showdown. In order to even get to this last match you have to beat the following below.  The Dice Pole Showdown lasts about 30 days and you can enter once per day, or use some bonus rolls to get more chances to continue playing. You may have to use bonus rolls that you have stored up and maybe even a "fresh start" here and there.  If you beat Kris Kringroll, then you get a vanity frame, 5,000 in XP, 40 snowflakes and a new set of custome dice! After you beat him, you continue to try to beat him for a total of five different "notches" on your vanity frame.

You don't earn more dice though. Pay attention to the score that they average because they will lose with anything slightly above it. I played one where they had a single box left but they had already achieved their average and they rolled a zero (0) on their last roll.

Chancer: Average score: 160, 50 XP earned and 1 snowflakes
Sixen: Average score: 180, 100 XP earned and 2 snowflakes
RollDolph: Average score: 220, 200 XP earned and 5 snowflakes

Topsy Turnowtiz: Average Score: 235, 300 XP earned and 2 snowflakes
Roller Bear: Average Score: 245, 500 XP earned and 4 snowflakes
Ruby Threes: Average Score: 255, 5K XP earned and 40 snowflakes
Fournament: Average Score: 270, 750 XP earned and 6 snowflakes

Twootsy Sweets: Average Score: 285, 2K XP earned and 5 snowflakes
Foursty The Snowman: Average Score: 304, 2.5K XP earned and 10 snowflakes
Nawty R. Dice: Average Score: 315, 3K XP earned and 15 snowflakes
Mrs. Kringroll: Average Score: 325, 4K XP earned and 20 snowflakes
Kris Kringroll: Average Score: 340, 5K XP earned and 40 snowflakes

I just beat him again.  This time, I only got the 5,000 XP and the snowflakes and it sent me back all the way to Chancer (the beginning) to start again. How far are you on the ladder?  Good luck!
