Description
And there you have it - my first zero portals 'puzzle'. A map dedicated to my friend Joric.
Back in February, he published a map which was a remake of the second room of this map.[forums.thinking.withportals.com]
Using his words, possibly quoting yet someone else: ''Room 2 is one of the best implementations of the Towers of Hanoi I've seen in any game, Portal or otherwise''.
Sadly, I couldn't even see the connection between that room and the Towers of Hanoi. But still the idea lingered. If that was one of the best implementations, and I couldn't even see why, surely I would be able to do it even better.
I thought about this on and off for a long time, but I couldn't find an elegant way to recreate this classic puzzle in Portal. This morning on the train I had a brainwave and it was so simple that I hit myself on the head for not seeing it sooner.
Therefore I proudly present you:
The Towers of Hanoi... in Portal 2.

I hope that you guys like it - at least, I'm really glad with the way this turned out.
I've just been thinking of this game much too abstractly lately, as a real pedantic mathematician should. But don't worry - after this I will be back to making regular maps again (probably :p).
Difficulty: 3/10.
Optional companion cube is obtainable - that's also a first.

Final note: the number of cube movements increases even more rapidly than in the original problem. Namely, for N cubes, the solution to this variant of the towers of Hanoi requires 2*3^(N-1)-1 cube movements, which greatly exceeds 2^N - 1, which is the answer for the classic version of the puzzle. Contrary to the result in my map Theorem, in which the complexity of the puzzle could only increase quadratically with the number of cubes, this time it grows exponentially. That's pretty bad.

Of course I won't copystrike you for the music if you record your run :p

As a person with object permanence I enjoyed it! :steamthumbsup:

The use of invisible triggers on this map was extremely frustrating to deal with, not the "makes you smarter" kind of frustrating, the "I have terrible object permanence and anything I don't see doesn't exist" kind. Every time I would bring a cube over to the other side, I would forget the fizzlers were automatic, destroy one of the cubes on accident, and would have to start the whole test over as a result. Please don't ever use automatic fizzlers again, or if you do decide to keep using them, leave a visual indication of where the trigger_multiple boundaries are so people with ADHD have a visual reminder that they exist, otherwise our brains discard the trigger's existence from our memory, resulting in the situation I just described.

Thank you for the recommendation. Both chambers are genius, and quite inspiring. Thank you once again.

@Crimson Pheonix I appreciate your dedication! You might be interested to check out this map which somehow completely blew this implementation of the same concept out of the water... I think it's genius!

Alright, I've played this test so many times now that I have become obsessed with the concept, but I don't have enough brain cells to recreate something like this without just copying some one else. I've played this chamber enough times that I don't make any mistakes anymore though, which makes me happy and all the more satisfied.

BTW, N=4 was what drove me crazy. Still good though.

I really liked the puzzle, despite it taking me a very long time to complete. Honestly, there was nothing that felt more satisfying than the reward at the end of the extra hard puzzle. I don't usually like a long puzzle like this that drives me almost insane, but this one was different. Thank you for the puzzle, and keep up the good work. :steamthumbsup:

Really satisfying to find the algorithm! After a bit I didn't even know what I was doing and was just bhopping around while my brain was in automatic.

A ton of running in this. Bunnyhopping is the quickest way to solve this if you already know the algorithm.
