I’m new there and i’m addicted to the game since some days. I spent my days on it *o*
I’m from France, the english is not my main language, i’m sorry for my mistakes if i have
And I have one question about the golden egg spin… I don’t have understand about the “time timing”
Welcome to the forums! I hope you enjoy your time here.
Timing is supposed to be impossible, so that is what it is, it is completely random, timing is impossible 
Hello and welcome to the forums! Can’t really answer your question, though, sorry. D:
The golden egg spin It’s fully random…? Bad news because some ark is only obtainable with this…
It’s a bad point about the game, we can’t make trade with others… =/
No, all arks are eventually obtainable via Online Missions, I think. But you’ll have to wait, which, a lot of us don’t really have the time or patience for, so, I get you.
Still, some of these non-OM arks (the dragon hatchlings and starters especially) do require time and patience, so, I guess that pretty much nullifies my point. Haha
Anyway, yeah, the arks in the golden eggs can be obtained in other ways. It’s just that it takes a lot more effort.
For the online mission i really want the number 268 it’s look like a ninja! *o* (I think it’s never come in a online mission)
For the starters and the baby hatchlings, i do the “Metallodious Trick” and i have catch all of this 8 in S Rank (fusion and omegawyrm included)
And for the last point, it’s just very very frustrating! I really cannot have this ark:
samuraice
iceratops
copperhorn
volcadog
vegikit
bluecub
darkpaw
starleo
pegahoof
They have no any method at all for the golden egg spin?
No, Gold Eggs are supposed to be completely random
Ok, be patient then! Be patient!
Unfortunately, bluecub was a reward in the very early launch days. I don’t think you can get it anymore, through anything, which is a real bummer. 
I may be wrong, though. So don’t quote me on that.
Bluecub is also on the golden egg spin but i never found one. Soo rare!
Oh, they’re in the gold egg. :0
They can’t be found in online missions or in the wild though, so I think that’s about the only ark you can’t get through anything but the gold egg. 
Yes, just save and collect gold for get this famous bluecub! =)
