Initial line & color logic solves 88% with only red remaining.#3: Web Paint-By-Number Robot (webpbn) on Mar 11, 2024
If you extend any of the remaining red 6s to the edge of the available area, it will make a 6 on a 90 degree rotation invalid. LL to finish from there.
Found to be solvable with moderate lookahead by wombatilim.
