I mean, I kinda liked Tower of Hanoi...back in the 80s, on my C64.

Ah so that''s what it called

I remember Beyond a Steel Sky got a puzzle with that rule

Ah, a computationally solved puzzle. So simple that even a cryptography website (the classical kind, not computer kind) has a solver for it. C'mon.

A classic puzzle and programming exercise.
Also featured in Mass Effect.

Nothing against a decent puzzle game, but calling this "beautiful futuristic art" is kinda pushing it.

Ho Chi Minh City Puzzles when?

I agree with Darvond that this is a very trivial puzzle game for someone who knows the algorithm for solving this - and you do need the algorithm to solve it in the general case or you are going to spend a lot of time backtracking.

However the game's lowest price on Steam has been $0.60.

So expect this game to be $4 and on sale at 75% often?

I like minimal graphic puzzle games, but the issue here is that these aren't really puzzles. It's all about knowing the algorithm for solving them and once you've figured it out, they stop being a puzzle to figure out and are just easy. I have strong doubts about wanting to play a game just full of them. If it ends up on sale super cheap.... maybe?

Cool more puzzles, though I wish you guys would get the entire ReThink series here, holy fuck are they addictive, hard as nails, and insanely satisfying!

FPPuzzlers are indeed an addictive genre!

The puzzles in this game change the layout from the original three-positions to hexagonal boards and discs of several colors. The original algorithm is of little use.

This novelty does not make the puzzles harder though. It took me less than 1 hour to 100% the game on Steam.
Only recommended on deep sale.
