#1: Wombat (wombatilim) on Mar 7, 2023 [HINT]
Initial line & color logic completes 38% with only black remaining.#2: Wombat (wombatilim) on Apr 10, 2023 [HINT]
C6: EL marks R1-6 white.
C35: EL marks R1-6 white.
C34: EL marks R1-6 white.
C33: EL marks R1-2 white.
C32: EL marks R1-2 white.
R24: If C10 is black, R24C20 must be black, but R23C20 must be white, and we need a 2 in C20. Therefore R24C10 and R24C20 are both white.
Stuck here for now, currently at 40% complete.
C7: EL marks R4-5 white.#3: Web Paint-By-Number Robot (webpbn) on Apr 10, 2023
R23: If C20 is black, it makes R22 invalid. Minimal LL.
R24: If C21 is black, it makes R23 invalid.
R23: If C21 is black, it makes R22 invalid.
R22: If C20 is black, it makes R21 invalid. LL.
R23: If the 5 goes farther left than C25, R24 would be invalid. R23 C22-24 are white.
R23: If the 5 is in C25-C29, the 2 in C25 would need to go to R24, starting the 4 and completing both rows. R25-26 would then be made invalid. R23C25 must therefore be white.
R23: Any remaining position for the 5 will place at least 2 blacks into R22. R22 C21-23 can be marked white.
LL to finish.

Cute, cute, CUTE! Lol...looks as if it could be a bit of a cross between a cute bunny and a cute donkey, doesn't it?
