So nice to have a simple and expectable rule set, combined with a nice picture each time. Thanks for setting these up! (as a side note, I also think it should be 2* rather than 3, difficulty-wise)

I like this constraint too, thank you for sharing. However, I suggest 2/5 for this one, less than 15 minutes for me.
