So kanji involving the left side of 状, Skritter seems to accept both the vertical line first, or the two little thingies to the side first. I've noticed with a couple of other things too. Like anything involving the enclosure 成 it will accept the vertical line to the left first or the top line first. Has anyone else noticed this too?

The Skritter team recently blogged about this. http://blog.skritter.com/2011/10/stroke-order-for-perfectionists.html

By the way, for 成, I'm pretty sure Skritter doesn't accept the leftmost slash first... I could be wrong though.

Hmmm. I'm also seeing it with character with 女 in them. Which is super confusing. Like 妄. It'll accept any stroke first.

Did you read the article? After research, it was decided to accept any of the three strokes of 女 first.

Unless there's a bug, all of these variations are deliberately allowed as correct by the Skritter team.

Sorry, it kind of confused me. I'm in Japanese, so I don't understand the way they write out the stroke order. And also, it's uncommon (but not unheard of) for Japanese Kanji to differ from Hanzi. Do they have something similar to this for Kanji?

An example of this (kind of) is that in the character 惧, only dots first is supported, despite what is written in that document.

I don't believe they do. I always assumed that, as far as Skritter was concerned, kanji and hanzi follow the same stroke order. However, you're right; stroke order does differ in Japan.

There's a little bit of info here: http://en.wikipedia.org/wiki/Stroke_order#Stroke_order_per_polity

In any case, it seems to me that, where there are multiple acceptable stroke orders, Skritter generally allows for it.

For Japanese, it's much easier, since there's only one stroke order standard. We still allow a few variations for characters that are unclear or annoying, but not nearly as many as in Chinese.

If you feel like a Japanese stroke order should be changed, use the stroke order correction feedback in the lower right of the study page and George will check it out.
