Initial LL only gets about 6% done. C17 is complete but very little else is marked.
R1: EL marks C20-25 white. LL.
C25: EL places the 7 in R9-15 (you need to look at how it affects C23 to white out the top part). LL.
C21: Whichever way the 3 goes, R7C20 is black. LL.
C7: IEL places the 4 in R4-7.
LL to finish.
