I have never gotten that much but, here are some tips: (Have a Good Player challenging you)
Get about 28-30 on first round, Get at least 28 next round and let other team win. Because of letting other team win, you get another round. Use this round to get at least 29. If you got 28 for round 1 and won, and seconr round 28 and lost and last round 29 you should get 85
