Drew the gachapon once, using up 6 chances to draw.
Counting the reward from the green gachapon, Liu Zheng just has 1 chance left.
If he wants to draw again, he needs to increase by 5 more chances.
That is to say, he would need to offer at least a mid-high value excellent quality item.
Liu Zheng had to think carefully about how to get the best cost-performance ratio.
It's known that out of nine gachapons, one must be a grand prize, and also out of nine, one must be a luckier item than the "Lucky Clown Card".
If the prize pool is sorted by value, then the grand prize is either that luckier item or something of even higher value.
So, he just needs to aim for the grand prize.
According to the rules stated by the Clown Box, the chances needed for drawing nine gachapons are 1, 2, 3, 6, 12, 24, 48, 96, and 192.
And when he draws the fifth gachapon, the probability of winning the grand prize is over 50%, and he only needs 24 chances, the same as drawing the sixth gachapon.
