Lucky Card Event. I think I have it figured out. This the event where you can choose to win 260 plasma if you guess which of the 10 boxes it is hidden under. If you have noticed it is usually under the 8,9,10th box you guess. It takes 96 coupons to turn over all 10 boxes. The odds are not based on the 10 boxes. The odds are based on the 96 coupons. Guess #1 you have a 1 in 96 chance of getting 260 plasma Guess #2… 3 in 96 chance Guess #3… 6 in 96 chance Guess#4… 10 in 96 chance Guess#5… 16 in 96 chance Guess#6… 24 in 96 chance Guess#7… 36 in 96 chance Guess#8… 51 in 96 chance Guess#9… 71 in 96 chance Guess#10…96 in 96 chance I wait till I get 96 coupons till I play. 100% chance of winning the 260 plasma. This is just a guess but I think the odds above are close to what you get over the many times you have played this.
