With Bucephalus' VIP perk of Mass Boarding:

I was only able to find Reserved Boxes when boarding just a Single horse (be it in my Center, or someone else's)

I was only able to find my own Center if the boxes were not reserved, and I had enough for however many horses I was trying to board. (I had to search for my center/hope it showed on the page when boarding)

For those concerned about how Mass Boarding could impact their center's Prestige/Lessons if they have a skill requirement...

What centers I could see to board horses in was limited by the skills of the horses I was trying to board (ex. 5 horses with 2000 skills, 1 horse with 500 skills - none of the Centers that showed had a skill requirement of over 500 points.) So the Center's shown will either;

A. Have no skill requirement

OR

B. Have a skill requirement that is less than that of the horse with the lowest skills in the set

Pass wise (as you can use Passes to get extra Candy/Children to give the candy to) - most calculations are coming up with this as needing between 20 to 40 Passes to complete the event - depending on one's luck of getting candy they need by 'free methods', if they can craft some or not, and what the children ask for.

If you are honestly wanting to know how many pieces of Candy in general this would take...this is one of the better calculations I've seen (though I can't guarantee if it is 100% accurate or not - take it with a grain of salt:

*Copied from a post made by Cyredanthem on Preprod:

So it takes 275 children with 100% satisfaction to get everything. Each requires two candies, so that's 550 candies, assuming no duplicates (which we KNOW won't happen).

Day 1 - 5 kids, 23 candies + 2 candies
Day 2 - 6 kids, 23 candies + 2 candies
Day 3 - 7 kids, 23 candies + 2 candies
Day 4 - 8 kids, 23 candies + 2 candies
Day 5 - 9 kids, 23 candies + 2 candies
Day 6 - 10 kids, 23 candies + 2 candies
Day 7 - 11 kids, 23 candies + 2 candies
Day 8 - 12 kids, 23 candies + 2 candies
Day 9 - 13 kids, 23 candies + 2 candies
Day 10 - 14 kids, 23 candies + 2 candies
Day 11 - 15 kids, 23 candies + 2 candies
Day 12 - 16 kids, 23 candies + 2 candies
Day 13 - 17 kids, 23 candies + 2 candies
Day 14 - 18 kids, 23 candies + 2 candies
Day 15 - 19 kids, 23 candies + 2 candies

Total = 180 kids (65% of needed) and 345 candies (63%) free + 30 candies from the Flash Sales (5%).

I don't see how " It means that if you connect on the game every day during the contest you will be able to receive more than 20 children a day." unless the contest is going to be longer than 15 days? Or there's something I've missed?

*Keep in mind, Preprod testing sessions are shorter than actual promotion run periods (ex. the Pinatas on Preprod were only 14 days - here, they are the standard 19 days

Does anyone know what the next event will be?

Is it true that the bulk registration or something isnt possible to do as a co? Bc on my test server, I cant do it to someone elses horses on co..

That seems to be the case.

I authorized shared management of ShorahNagi to ShorahTest (an account that I use on Preprod to test things from a new player's perspective (you are allowed to make another account on the Preprod server for this purpose *only on Preprod is multi-accounting legal*))

Well, when I went down to the bottom of the page (where the option to move horses in bulk is for VIP/Pegasus account holders) and the option of "Board at Equestrian Center" was missing from the list.

From Preprod - these are the average amounts of points one can find in a HOP for certain Pinatas (based on the use of 5 HOPs per Pinata - you may need to use More/Less on a Pinata)

Pinata 4: 15, 12, 16, 16 (14 points)
Pinata 5:15, 18, 13, 12, 16, (14 points)
Pinata 6: 33, 31, 31, 29, 26 (30 points)
Pianta 7: 35, 27, 28, 26, 34 (30 points)
Pinata 8: 28, 25, 29, 35,(28 points)
Pinata 9: 50, 59, 61, 50, 52, (54 points)
Pinata 10: 69, 59,52,70, 61, (62 points)
Pianta 11: 59, 57, 59, 50, 50, (55 points)
Pinata 12: 102, 108, 110, 113, 139 (110 points)
Pinata 13: 129, 137, 115, 125, 119 (125 points)
Pinata 14: 102, 140, 125, 138, 112 (123 points)
Pinata 15: 279, 273, 201, 237, 262, (250 points)
Pinata 16: 251, 251, 275, 234, 242, (250 points)
Pinata 17: 279, 269, 201, 262, 228 (247 points)
Pinata 18: 496, 428, 448, 512, 420 (460 points)
Pinata 19: 522, 500, 536, 526, 468 (510 points)
Pinata 20: 542, 525, 559, 493, 558 (535 points)

As I advised in the original posting of this - I recommend using HOPs *mostly those you might have in your inventory* early on for a few reasons:

1. Gain access to the 'harder' Piñatas sooner (thus, more time to work on breaking them)

2. Gain access to additional objectives to make later Piñatas easier (ex. more points per click)

3. Allows you time to gather additional HOPs/Passes to be used later in the Event if you need more help to break them.
