Furthermore she already had some strats already, because she kept telling Kyo to "draw a comma", something that was actually fairly effective on the earlier levels (but wasn't obvious at all, most people would either draw a square or circle).
In the later levels, she relied on backseating from chat, this is clear because the solutions she came up with were being posted in chat, and she kept begging the chat for advice. But at the end of the stream, she pretends she wasn't backseated at all, and claims "it was all me".
The fact that she didn't have all the answers ahead of time means that she probably got her knowledge of the earlier levels from watching a video, rather than diagrams.
