Thank you very much for creating and sharing this wonderful puzzle. I don’t know why my poor old brain couldn’t imagine the full rank constraint the other way round …

Reverse ranking did my head in - made so many mistakes! But if you can get your brain the right way round, not too difficult, and a good solve. Thanks!

Combination of skyscrapers sums and full rank made for a smooth solve. Max 3 * imo. Only the reverse rule tried to get me off track at times. Thanks for this beauty.
