Pre-Release Review
Posted: July 21, 2014
*reviewed using press copy provided by developer

beautiful way to make a puzzle game. easy to play and each level is extremely well made, so much time and planning must have went into this.

wonderful if you're a fan of slider puzzles. no chemistry knowledge required, it might be helpful but the design is intuitive. everything makes sense right away, no timers either!

just a nice little game for basically anyone

(if you're colorblind, everything's well labeled and the colors are only cosmetic, no matching light green to light blue with a 3 second timer. if you can't see the border colors though that might be a major issue, maybe leave a comment if you can just to verify <3)

In an era where "innovation" means adding micropayments to a 15-year-old franchise, Alan Hazelden finds a unique mechanic, dresses it up in a design so crisp it comes with vinaigrette dressing on the side, and presents it like it's something he does all the time. Which it is, because he's some sort of puzzle-game-making superhuman.

If you don't play this game, you're not allowed to say you enjoy puzzle games to anyone ever again.

My brain is now puzzled. Even though you don't need any understanding of chemistry what so ever, if you enjoy puzzle games this game is most certainly for you.

At first glance, we may be reminded of the classic Atomix from the Amiga and C64 era. Apart from building molecules, this is an entirely different game that feels very unique and genuine. The staggering 144 levels will keep you busy for quite some time as it took me about 12 hours to beat. The puzzles themselves are easy enough for the average person to beat while not feeling silly doing so and difficult enough to challenge every mind. The basic premise is controlling one atom to move, bond, break, turn other atoms to complete a molecule - all within a set of boundary. The only letdown is atom variety as you'll only be seeing C, O, H, N and He which can and will get boring once you're close to completing the game.

It is worthy of mentioning that the game runs on Adobe Air and there have been reports coming from Linux users that it does not run on some occasions as Adobe has ceased linux support.
Although the game would greatly benefit from Steam Workshop integration, the developer has stated he does not wish to implement such features in the foreseeable future - a shame as user created levels would keep the game and its community alive for longer.

For the fan of the puzzle genre, Sokobond will quench a thirst for simple 2D puzzlers. The average gamer should give it a try as its addictive nature may surprise you playing it more and more. If you have a personal vendetta against these types of games - stay clear of this one.

"Sokobond" is the best kind of game - one that is fun and educational... FUNDUCATONAL, if you will. This elegant little puzzler is a lot like that science teacher you had in middle school (hi Mr. Hellmund! Why yes I've applied myself - I review video games in my free time!) who's enthusiasm for the scientific method is only eclipsed by his increasingly colorful ties. This is pretty, this is challenging, and you'll learn a thing or two. And don't be too intimidated; this game doesn't require you to know a lick of chemistry. If you're a fan of puzzlers and like factoids, check it out. I think it's a refreshing change of pace. It isn't BREAKING the mold, not really. This has been done many times before, but that isn't really all that BAD either.

I usually don't write reviews, but from the minute I started this game I was amazed! Really smart ideas and I really love how there's small notes about every molecule! I'm a lab geek in profession and this was right up my alley <3

Sokobond is a nice little puzzle game with some questionable views of chemistry.

The game involves you controlling one atom in a grid structure, and you move the atom around the grid forming bonds with other atoms [or not, in the case of noble gases]. Each atom is a simplified representation of its real-world counterpart, focusing mostly on the number of bonds it can form.

The puzzles in this game range from simple to quite tricky, and it took me quite a few hours to complete the entire thing without cheating. [Don't cheat, it's very satisfying when you solve a puzzle]. The mechanics require you to do a lot of lateral and reverse thinking, which is quite good.

Simple graphics and sound design, which works well for a puzzle game. The controls use either a keyboard or a controller, both of which are again, very simple [LUDR + undo/reset].

Definitely a good simple [but not easy] puzzle game.

Sokobond is an excellent puzzle game. It is a psuedo chemistry game where you have move an atom around a grid forming molecules by touching other atoms.

The game requires precise moves, in the right order to create the correct molecular bondage. It is so fiendish that it offers a real challenge and lots of head scratching despite providing an infinite undo.

The game is also nicely paced and the level menu is well designed, unlocking levels as you progress. I found it simple to pick up, and new concepts were introduced steadily.

I love puzzles but I usually play them in small doses.

The two hours I've played Sokobonds were in one sitting and I stopped because it was getting late. Fun and addictive.

Addendum: The facts on the bonus levels are hilarious.

If you like either puzzle games or chemistry, then Sokobond will be right up your alley. The core component of Sokobond is to combine elements together to create molecules. Sounds simple, right? As with any other puzzle game, the puzzles in Sokobond can become deceptively hard. Whilst the design is simple, it doesn't distract from the core gameplay.

After you get to grips with the understanding of the molecule fusion, the game will throw a few curveballs at you, allowing you to split bonds or create double bonds, for example, furthering the possibilites of creation and puzzle solving. A small neat touch is that after you beat a level, you're given a fact about the molecule you just created. You really can learn while you play!

Overall, for it's price and enjoyability, Sokobond gets 8.5/10.

Beautiful and simultaneously frustrating. This is a puzzle game you want to try. You will always come back to it again and again, until you complete it, after agonising hours of brain strain and walkthroughs. But it will all be worth it, and you will try again, or recommend the game to your like-minded friends. And the cycle will continue infinitely.
Great game though. Everyone should give it a go.

When I hear Zach Barth say that a puzzle game made him want to stab himself, I expect that game to be made from the stuff of Satan's nightmares. As it turns out, Sokobond is made from more palatable material, and Zach's quote is made from hyperbole. This is not a criticism, mind you - when you have 124 puzzles in your game, you don't want inordinately difficult roadblocks impeding access to the rest of them. Progression is handled by way of a grid in which each puzzle is represented by a square and successfully completing it unlocks adjacent squares. The challenge curves out nicely, and if there was one puzzle I had grown tired of there were usually at least a half dozen others I could divert myself to.

The trailer shows you pretty much everything you need to know about the game mechanics. In every puzzle you take control of a single molecule which has a certain number of bonds it can make - anywhere from 1 to 4 - and will automatically bond with any molecule it comes into contact with, provided that that molecule also has spare bonds available. If it doesn't, then you are able to push that molecule elsewhere in the level. At fixed points in the environment are spaces which will separate bonded molecules, increase the strength of molecules' bonds (i.e. if 2 molecules are bonded, and each have another bond spare, running them through such a space will remove the spares by giving them a double bond), and reorientate the molecules' positions. That's it. It's essentially a block-pushing game with a novel twist.

The goal is to connect all of the provided molecules in such a way that there are no remaining bonds. In some levels the challenge lies in working out in what order and in what arrangement a small number of molecules need to be collected and placed to use all their bonds, while in others the challenge lies in piloting a huge snaking line of molecules around a very limited space, making sure that certain parts of its body never touch others in order to avoid undesired bonds. Some levels even see you take control of helium, which has 0 bonds available, meaning that you can only create the end product indirectly, via environmental manipulation. Though, as other reviewers have pointed out, the chemicals you will be making are frequently the same, the way in which you make them is always fresh and different - no small feat, given the amount of content on offer.

I enjoyed my time with Sokobond and would recommend it to anyone looking for an intermediate level of challenge. It's certainly not even in the same universe of hellish difficulty as Zachtronics games. It's not the most amazing or memorable puzzle game I've ever played, but it is thoughtful and well designed.

Overall score: 3.5/5

As a footnote, I'd like to say that I did not enjoy the bonus levels unlocked upon completion of the other 124, however as they are presented in the context of a bonus this did not affect my opinion of the game one way or the other. I will talk about them anyway, because they serve to illustrate the difference in 'feel' regarding the sort of puzzles I enjoy, which is useful info if you share similar preferences. The bonus levels adhere to the 'needle in a haystack' school of puzzle design, in which there is only one route to the solution and a single misstep will render the puzzle unsolvable, however this will not be apparent until several steps further down the line, leaving you to wonder which of the many previous moves you have made was the wrong one. With a few exceptions, the main game's puzzles allow you enough leeway to experiment and come upon an 'a-ha!' moment organically, and if it has become unsolvable this will be immediately apparent. The latter feels as if I'm slowly being guided to a solution via process of elimination, while the former gives no feedback whatsoever, making it more frustrating than fun. The great majority of the puzzles in Sokobond are fun.

WARNING for Linux users: it requires Adobe AIR, which is not supported for Linux anymore. Check the forum discussion ( for more info.

Aside from problems with Linux support, I found the game itself to be very good.

The "science" element of the game is a bit overstated, though there are some interesting facts about chemical compounds revealed after you solve a puzzle. Otherwise, it's a very well-made and challenging puzzle game!
