Today I got a 3. And I beat wordlebot too. Although this time it admitted I was good.
wYYww I didn't use my second rando today.
YwwYY Two of the three Yellows were also yellow in the first word.
Got it. There were a couple of directions I could go but I chose to try this one instead of the alternative and it worked.
The alternative guess would have yielded YGwGY after which I'd have gotten it in 4. But as it is, I got it in 3.
