For those new to Ningin, we give out various poster and album prizes to our top users every week as deemed by their total contributions to Ningin which our EXP system keeps track of. I wrote a definitive guide about this last week. Ningin’s traffic and userbase has grown tremendously in the past couple of weeks alone and it’s becoming harder for people to win these Weekly EXP Prizes. I have an idea of how to make things a bit more fair but would like your feedback.
Starting the week of May 2nd, I want to try a different method of determining weekly EXP prize winners. Instead of automatically giving the top 2 people prizes every week, I want to add an element of randomness so that multiple people will have a chance while still giving the top scorers an advantage. So my idea is to combine the scores of all the top 10 weekly EXP users then select two winners based on the percentage of their total scores. Let me illustrate this further:
At the time of this writing here is our current top 10 (these scores are fictional, just made up for easy math):
xhabb - 5000 points
Lilsparky67 - 4500
Kizuninha - 4000
IC3_K155 - 3500
karens2 - 3000
Niecydc - 2500
AnabelStars - 2000
MeiMeix3 - 1500
conkwe - 1000
crimsion29 - 500
The total of all 10 users is 27500. However, to make it fair for the top three users that are used to winning, I’m going to count their points twice. The adjusted scores are as follows:
xhabb - 10000 (5000 x 2)
Lilsparky67 - 9000 (4500 x 2)
Kizuninha - 8000 (4000 x 2)
IC3_K155 - 3500
karens2 - 3000
Niecydc - 2500
AnabelStars - 2000
MeiMeix3 - 1500
conkwe - 1000
crimsion29 - 500
And the total score is now 41,000. To determine each user’s percentage of winning, I’ll divide their score by the total, which would look like this:
xhabb - 24.40% (10000 / 41000 * 100%)
Lilsparky67 - 21.96% (9000 / 41000 * 100%)
Kizuninha - 19.51%
IC3_K155 - 8.54%
karens2 - 7.32%
Niecydc - 6.10%
AnabelStars - 4.88%
MeiMeix3 - 3.66%
conkwe - 2.44%
crimsion29 - 1.22%
xhabb has a 24.4% chance of winning based on her weekly EXP totals, Lilsparky67 has 21.96% chance of winning and so on all the way down to crimsion29 who would have a 1.22% of winning. The top 3 still has the best chance of winning, but everyone else will have some chance of winning as well.
Yes this is a bit more complicated, but it doesn’t change how you should interact with Ningin. I’m just looking to make things a bit more fair for all. Most of you won’t even care about this, but I know I’m going to get asked questions, so this will save me time later. Whether or not it’ll be permanent will be determined by your feedback.
For those wondering why we only give out two weekly EXP prizes instead of three like in the past, well, that’s not entirely true. We have something like 4 giveaways on Ningin, not to mention the other bonus giveaways or giveaways on the other sites in our network. Really, our average giveaway is very close to 1/day if you count all of those. Anyway, that 3rd weekly EXP prize has become out Weekly Twitter Giveaway. In the past the comments were that Ningin needed more random prizes. And as you can see, we’ve done that. Even if we kept it at 3 weekly EXP giveaways, then the 4th person will complain about not winning. As much as we want to give everyone every copy of every poster/album, that’s just not possible. But we can try to be more fair about how we give out the copies that we do have.
