This is a 3D programming puzzle game with a mini-story added on for fun. Care was clearly put into every aspect of this game. It looks amazing, and it's fun to play!

I can't think of a single negative thing to say about Infinifactory. The puzzles slowly build up from blatantly obvious to extremely challenging, teaching you along the way how to use the tools you're given. Every so often you get a new block type that will allow you to take more control over how your machines work. The scoring system shows how well you do compared to everyone else in terms of number of how quickly your factory produces the output, the footprint of your factory, and how many machine blocks you used, but there is nothing wrong with making an overly complex or inefficient machine so long as the final product is correct. This makes the game accessible to a wide audience since it doesn't matter if your solution uses 20 blocks or 2000.

The key to Infinicatory's success is that it layers a bunch of simple mechanics that enable you to build complex and open-ended solutions to each puzzle. The blocks you have at your disposal are equivalent to a basic programming language. The puzzles are only as challenging as your creativity allows. There are nearly an infinite number of solutions, and all you need to do is come up with one that works.

Do you like logic puzzles? Do you consider yourself creative and capable of abstract thought? If so, do yourself a favor and buy Infinifactory right now.

Found this game quite boring and not that fun , shame as it does have potential i think it would also be quite fun if you had a "sandbox" Option.

How to solve a puzzle in Infinifactory:
1) Look at the output and think, "That's not so hard, let me put this here and that over there."
2) Run your experiment.
3) Swear because it's nowhere near what you thought it would be.
4) Swear again.
5) Come up with a rickety solution that works under one use case but falls apart on others. (This is exactly like some real-world programming!)
6) Marvel as your friends come up with more elegant, faster solutions.
7) Realize that you're having a tremendous time.

I don't know what Zachtronics has against the human brain or why he wants to punish it so, but I encourage his behavior. Great game, they've been very good about expanding it and refining puzzles. Recommended.

It's straightforward. The mechanics are simple. The purpose is clear. There's no confusion as to what you are expected to do and what tools you have to do it.

It's diabolical. The puzzles are sometimes bananas, requiring some pretty twisted logic and lateral thinking. While you strive for a solution, there's a constant nagging feeling that sometimes your solution is just inelegant and you need to do it better.

It's oddly darkly humorous. There's a strange undercurrent of defiance against your alien overlords, from listening to the audio diaries of the project managers who came before you, from resenting the food pellets that drop into your cell when you complete sections of the game.

It's also gorgeous - not so much in graphics, which are perfectly adequate, but in the efficiency of the presentation. No main menu. No weird visual effects cluttering up the screen. No unnecessarily ostentatious setpieces. No splash screen! On load, the game drops you right into where you left, so you can literally load the game and get building. There's a gorgeousness to seeing your machine, your factory do its work, and the satisfaction that comes with it makes the effort all the more worth it.

It's one of the most interesting puzzle games I've ever played, and I'm enjoying it hugely despite not being great at coming up with particularly creative solutions.

Early Access Review
Posted: January 19, 2015
This game is freaking awesome. Don't let the Early Access tag scare you, because it's pretty far off, and it's already worth every full-priced penny in it's current state even if the developer decided to walk away tomorrow (which I'm sure Zach will not do)

The best thing about this game (and SpaceChem before it) is the awesome feeling of "♥♥♥♥ yeah, I'm such a badass for doing this ♥♥♥♥", that you get after each level completed. And in a way you are, as this game is a lot harder and smarter than most games out there.

- "I'm such a bad-♥♥♥" feeling
- Great tutorial/intro
- 3 solution slots per level
- Spacechem pyramid dangling in the rear view mirror in the intro
- Learning curve is very well balanced
- Stable and polished

- No in-game recording and sharing tool (ok, this shouldn't be a Con, but we got spoiled...)
- No or too few data points to compare performance (this will turn into a Pro later, as this feature is awesome)

Graphics are functional but nothing to write home about, neither Pro nor Con, but certainly good enough.

I recommend you pick this up at full price if you can, as this is one developer that deserves more money so he can make more good stuff like this. The fact that H1Z1 is topping the top selling list while people put this game on their wishlists waiting for a sale just makes me want to cry. So go ahead and pick this one up sooner rather than later.

Infinifactory does this thing I love. It makes you earn your enjoyment of it.

You load up your next task and take a look at what you'll need to produce and what materials you'll have to produce it with. Immediately, some ideas start popping and you think, "Okay, I know what to do." Ten minutes later, everything's wrong and you realize you were being naive. But you keep building and trying things because that's just who you are. An hour later, things start to click. You still feel dumb as bricks but you're at least smarter than you were ten minutes ago. Then, long after you began, you have a working production facility. You are a genius. The smartest of the smart. Nothing can bring you down from this high.

Then you get to see how your solution rates against everyone else who's finished that same factory and it turns out you're actually pretty much middle-of-the-road. But maybe you can go back and adjust some things and score better? Or maybe you've learned some things and maybe your vision and clarity has leveled up and just by starting fresh you can shave your score by half?

Whatever the case, you have had a blast. You've been challenged for the first time in who knows how long. You've had fun and by all the things that you might even consider swearing on, you've earned that fun.

SpaceChem is one of my favourite puzzle games of all time. I adore its design and its open-ended puzzles. I was interested in Infinifactory because I liked SpaceChem. I was also skeptical. I didn't like the idea of doing puzzles in a 3D space. I didn't like the aesthetic. I didn't like the whole factory concept.

I needn't have worried. Infinifactory is actually probably better than SpaceChem. Which hurts me to say. But it doesn't hurt too much because I'm busy having tons of fun.

I can be very brief about this game:

If you like Zachtronic's SpaceChem, you will like Infinifactory.
If you love SpaceChem, you will love Infinifactory.
If you hate SpaceChem, you will hate Infinifactory even more.
If you think SpaceChem is too hard, you will find Infinifactory undoable.

If you never played SpaceChem, what are you waiting for? There is a free demo available. And if you enjoy it, rest assured that you will enjoy Infinifactory too.

Heartily recommended for all those who love tough puzzles and enjoy building complex machines.

Spacechem in 3D -- Still in space, and still one of the very best puzzle titles you can play. It is one of the elite that can occupy your mind long after you shut the game down. I find myself in conversation, or trying to work, or watching TV with the family, but my brain is ELSEWHERE, dreaming of new algorithmic design patterns and potential optimizations. Even when I'm sick of this game and abruptly close it out of frustration, more than once I have booted it immediately back up.

You will emerge from the other end of this tunnel, bloody and blackened with industrial soot. And you will be the better person for it. THE END

If you haven't tried zachtronics games you are missing a great deal of puzzles. This time they come back with mindtwisting manufacturing puzzle. Although it's called "Early access" the bugs are minor (haven't got a crash, but some options are missing) and developer is actively involved in both puzzle tweaking and further development.

As for the game itself? It's very polished. Puzzles are start out easy enough and involve some that are easy but not obvious (a thing that is missing in A LOT of other games) until they get harder and harder. Each level (probably while it's in early access) features a questionnaire asking for your opinion of this level.

All in all this is very good and game for all puzzle lovers and constructive mind people.

I should've made a review for Infinifactory some time back but I kept putting the time off, waiting for the time when I could make a review worthy of such a fantastic game. I fear I will never be able to do the game justice, so here goes with a short review as ideas simply pop into my head!

As you can notice from my first parapgraph I think extremely highly of Infinifactory. For some time I was searching for a puzzle game with great replayability. I heard about and played Spacechem, which is an impossible game not to mention when reviewing Infinifactory. Both are developed by Zachtronics and both employ identical mechanic, but Spacechem is in 2D and Infinifactory is 3D.

The essence of the game is to take some materials as an input and manipulate them via building a machine/factory from different types of blocks to conform to the required output. So you may have to rotate and weld two different types of blocks together or receive a broken item, remove the broken parts and replace them with good parts. The variety of puzzles is very good and you don't feel like you're repeating the same processes during your progression.

The beauty of both games is that each puzzle can be solved in maybe an infinite variety of ways, so once you have made a solution you can go back and attempt to streamline various factors of your machine : footprint, cycles and blocks used. Very similar to engineering projects in the real world!

Hopefully some of your friendlist will also play the game as in game leaderboards are included for each puzzle to further the replayability. There are slots to save three of your machines for each of the puzzles, so you can purpose build a machine for each of the scoring criteria e.g focus one machine solely on having the smallet footprint possible even if it is at the expense of being less efficient and having an increased cycle count.

I'm approaching 60 hours into the game and I am half-way through the second campaign of the two. I've gone back and fine-tuned a few of my older machines and completed a couple of the community made puzzles. There are literally hours and hours of gameplay available. I'm generally not a "sandbox" type of guy either so Zachtronics have definietly managed to include the magic ingredient with this one.

A lovely feature of the game is to be able to export animated gifs from a static camera point of your working machine, which will loop infinitely. It can be very satisfying to construct a particulaly nice process within your factory and watch it loop over-and-over.

The game has a slightly comedic and quirky story that holds the levels together and they progress in difficulty at a nice rate. The levels get a bit easier when you start the second campaign and then begin to ramp up again! There are some tough levels which may put off a few people that don't enjoy a mental challenge. I found myself trying to solve some of the puzzles in my head whilst at work!!

This is one of my favourite games of 2015 so the question of whether I recommend it is not a tough one at all!! It's easily worth the full price, I bought the game in a sale and feel a little ashamed for doing so!

Its a game that really makes you think, although I have a hard time solving puzzles I still get a lot of satisfaction from slowly putting everything together to make a finished production line.

its very complex and challenging and if you like a good challenge plus that tiny bit of satisfaction you get when something you've worked on for a while just falls into place then buy this now and enjoy it it will warp your mind a tiny bit as you have to strive to put together the most complicated designs and it will challenge your thinking about how to approach goals and to achieve those goals but seriously this game is soooo worth it even for the storyline that you have to piece together as the game goes on

I bought this game thinking it would be like a mix of Minecraft and Factorio. I was right. One weekend later, and I am dreaming conveyer belts and welders. I no longer want to sleep. This game is my life. Save yourselves. Run!

This is a problem solving game, not a puzzle game. If you like KSP or making contraptions in Minecraft you'll like this too.

This game is fantastic and it has both enough content and variety to justify the price.

Now that the summary is out of the way let me talk about the difficulty of the puzzles because that's really not so easy to summarize. Basically a great deal of the early puzzles can usually be solved by using the same solutions over and over with a few tweeks each time. But unlike other puzzle games where the point is just to solve the puzzle and how you do it isn't very important, Infinifactory asks you to get creative with your solutions. You are judged on how quick, efficient, or costly (number of parts used) your solution is and how difficult each puzzle is or much fun and enjoyment you get out of the game (especially the earlier levels) is based on how much you try to optimize your solutions. You can never optimize all three categories and the game doesn't expect you to since the categories aren't comparable. Is making the solution take 20 cycles longer worth reducing the power cost by 5? Who knows and who cares. You choose one category and try to max it. You'll also find that solving for one category asks you to solve completely different problems than solving for another so you can try switching it up if you ever feel like your solutions are getting stale. But more importantly is that when you try to maximize for something the specifics and layout of each level become much more relevant to your solutions. This change can the solution for each level drastically and will require that you do something different each time.

There is also a fourth category you can optimize and it's creativity. The game doesn't judge you on it but chances are if you're interested in Infinifactory you probably like the idea of building contraptions. Many times during a puzzle I would think to myself, "I wonder if I can do this" or "Would that even work" and I'd end up ignoring the categories and just building something that looked cool or was super intricate. With completely open ended puzzles and millions of correct solutions the game always lets you build the solution that you want to.

One of the best puzzle games i've ever played. If not the best.

You get some resources, some machine parts and a delivery portal. Your goal is to create a machine that assembles the resources and deliver the resulting object to the portal.

Easy at first, it becomes more and more difficult but without getting unfair.

Each puzzle is evaluated by 3 different scores:
- Footprint: space usage of the solution
- Blocks: the cost of the solution
- Cycles: the speed of the solution

When you solved a puzzle, the resulting score is compared with the scores from other players solutions. I really like this feature. It keeps me motivated to try solved puzzles again just to figure out a new solution that optimizes in footprint, blocks or cycles.

This game is one of Zachtronics' engineering/building games, which also includes SpaceChem and TIS-100. Although all three games are great, Infinifactory is in my opinion the best of the three. The big difference is the three-dimensional aspect of it (Zachtronics' slogan is "Like SpaceChem, but in 3-D!"). The 2-D nature of SpaceChem and TIS-100 sometimes leads to situations where it's very hard to see how to proceed to a solution without completely gutting your existing one. In Infinifactory, because of the third dimension, you can usually kludge your way to a working solution if you put in enough time. And that's where the brilliance of the game shines through: once you finish a level, you will get three histograms showing where your solution compares to other peoples' solutions in terms of speed, number of blocks, and total footprint. If you've done a kludgy solution, you won't score well, and it will bother you to the point that you will eventually come back to make a better solution. Elegance counts in Infinifactory, just like in real engineering! (Sometimes I come up with better solutions while sleeping, and I have to rush to try them out when I wake up.) So this game has massive replay value, more than any other game I've played. Also, I find that TIS-100 and SpaceChem feel kind of dry and abstract after a while, but the more tangible nature of Infinifactory doesn't seem to have this problem. There are only a small number of block types, but one of the delights of this game is that you are always finding new ways to combine blocks to form functional groups, which you then will use over and over again (starting by redoing all of your old solutions to use the new trick). If this sounds like programming, it is! If you're a programmer or an engineer, this game will be like crack to you. It has the same "feel" as programming, but the actual tasks are sufficiently different that it's still new and exciting. Pretty much the only negative thing I can say about Infinifactory is that you can spend way too much time on it if you're not careful. Oh, and if you're an expert and manage to get through all the levels, there are also community levels to continue to torture your brain, or you can create your own. So if you've liked any of the other Zachtronics games, or other building games like Factorio, you should give Infinifactory a try.
