Foreword

Wait, Skyscrapers?

If this were a book, I suppose this would be the first (meaningful) thing you read as you open it.

No, wait – we’re missing the pre-book acknowledgement,1 excuse me.

To Chepin, for sparking my love of Skyscrapers.

There we go.

This website is an archive of strategies, techniques, tricks and tips, rules of thumb, and everything else you could want on solving Skyscrapers. It’s a compendium of knowledge, an enchiridion of logic, a library of experience. It’s– ok I’ll stop. You get the idea.

Now this is more of a wiki than a book, so everything is fragmented rather than being part of one cohesive narrative. I didn’t write these pieces with any particular order in mind, and it’s pretty difficult to justify a suitable order. That being said, having one is still useful for those planning on reading the whole thing, so if that’s you, I’ve collected all the pages in a somewhat suitable order in Walkthrough.

I first came across Skyscrapers in late 2021, courtesy of the puzzles section of The Monkeyopolis Times (a fan-made Bloons newspaper on reddit, which I ended up becoming a part of). It’s been a fair while since then, so I can’t recall what happened exactly; but one way or another, I ended up quite enjoying Skyscrapers, and so they’ve become an occasional hobby of mine.

I created this website because I really couldn’t find anything else like it online. Maybe it’s just because Skyscrapers are fairly niche, or searching “skyscrapers” just isn’t the same as searching “sudoku”,2 or a lot of the ‘high-level’ stuff you can’t really ‘teach’ – but it felt a little weird to me for brainbashers.com↗ to have thousands of Skyscrapers puzzles, with no resource to unravel the intricacy behind their solutions and show others how they might reach them.

So, enjoy Skyscraping, and I hope I can teach you something new. If you’re reading this while the site is still under development (status: it is), I apologise for all the holes – I’m working on writing and adding all the pages!

  2. Searching “towers” is even worse.↩
