Cool but the canvas is too small and we need a better way to find elements and register found ones. We could get any better ways to give hints on reactions than the InGame "achievements". Looks like a prototype more than a full game, but it has potential, it would be cool to get missions like, do "this" with the given elements, we could learn... Still well worth it's price though, and it's almost unique but easier (and more limited) than its big brother "The Powder Toy" (free on pc and Android)

This is so much more entertaining than I expected. There's plenty to do, and it's all very satisfying - both aesthetically and in feeling. The only thing I feel is missing is a mix option to move things around, and gyroscopic tilt would add a little extra something - but frankly they're not needed. I've only played an hour or so but so far it is wildly fun. IMO it's well worth the money, I got it on sale but knowing how good it is I would gladly pay full price for it. 5/5 would recommend.

It's a really good should I say game or app? Well anyways it is definitely worth buying. It is realistic but instead of looking realistic it's pixels. I like it. The only reason why I'm not putting a five-star is because sometimes it gets glitchy AND because it doesn't have enough explanation for the stuff. ⭐⭐⭐⭐✴️

A really cool little app. It takes barely storage and is overall a good little app. I suggest adding more elements, possibly add some kind of pandemic, even though there is already a plague. I give it 5 Stars, well done!

I find this app to be very amusing! I've only learned basic concepts of chemistry. I'm trying to learn more. I just hope these reactions are accurate, so I know what reactions would really occur in real life applications. I'm enjoying this for now. Please add mainly nickel, chromium, and possibly molybdenum to create stainless steel. Also, I see you have iron filings, but please add carbon to create steel. You have steel, but I wish to go further. Metallurgy fascinates me. Thanks! Great app!

So far it's amazing! I'm having a hard time getting some reactions, but that's not the developer's fault. I love how I bought it and there are zero in app purchases! I hate when you buy something and then have to pay more to play! Keep putting out apps and I'll buy them because I like they way you work!

My favorite app. Its so much fun and there are so many ways to conduct experiments. One of the best apps on playstore. Dev ty so much. Please keep updating and releasing new reactionlab games. I will buy all of them!

fun, and a blast to the past as someone who spent a lot of time in similar games in the flash era with objectives to provide a little structure to the chaos

Joe. Z. Jul 22, 2019     

Fantastic sandbox game. Very fun to play around in. Getting all reactions (achievements) is very challenging but very fun to do.

Phi. H. Mar 21, 2021     

I love this app but unfortunately it didnt run right on my Realme XT running Android 10. Super slow. It's a fantastic app and fun to play.

The. U. Oct 28, 2019     

There are better particle physics games out there. This one has too small a field to really do anything interesting, and many of its elements do not behave the way one would assume they should.

Con. B. Sep 20, 2021     

Please add tons more elements cause I like this game. There are infinite possibilities and it's just got that spark to the game. THOUGH I DO SUGEST YOU ADD MORE ELEMENTS AND FEATUREA SUCH AS FAST FORWARD. PLEASE DO SO TO KEEP THIS FIVE STAR REVIEW. It definitely is worth the money.

G. C. Aug 16, 2019     

Got the game the other day and I like it. The thing i think you need to add is to make the place you make the particles alot bigger. Then i will rate 5 stars.

Jos. K. V. Jun 4, 2020     

Great game but the grafics can upgrade. Please make them more realistic. Otherwise i love it

Mar. S. May 16, 2019     

awesome science app! great sandbox game and you can make whatever you want. youre gonna need a pen to draw more elaborate creations

bos. k. May 18, 2019     

if you like physics this is a good game to start out with. you cant do much with moving liquids but it's fun I would recommend it

Jal. M. Sep 27, 2019     

I really like it! It gives me a challenge, but for the time I don't want to think hard, it lets me experiment.

A. G. u. Jan 23, 2019     

Great game with simple interface and controls, I look forward to ReactionLab 3 or further updates to this.

Man. t. M. Jul 24, 2020     

The game was fun until the searching mechanic broke. I can still play it but it takes long to find the thickener and stuff.

the. f. U. Oct 24, 2021     

It makes you learn and make technology but wish they added animals and engines and many more but the game is pretty good anyway

Gir. G. Oct 28, 2020     

I love this app! The only thing I could suggest is you should have a formula book for reactions or substances you have created already that way you don't have to remember all of them

War. H. Jul 19, 2019     

It would be good to get an update as the last one is from 2015. shared content needs tags and search function

Ric. B. Nov 1, 2020     

Such an amazing game! I honestly just hope that either more content gets added or another game gets made. As this and the first were so good. 😍

Dan. G. Mar 28, 2020     

A few major elements are missing, but a fairly fun game none the less.

Kar. M. Jun 3, 2020     

Worth every penny. Very fun time waster. Love that it isn't too expensive to buy.

Eli. G. Jun 8, 2020     

some hints (other than the vague ones) would be nice. love it otherwise.

not. a. f. f. Jan 23, 2019     

It would be good if you make that we would change the lab's size for more reactions to see.

Dom. K. Mar 17, 2019     

I'd like to see regular updates with new features, but that's only because I like it so much that I want more.

NIC. P. Oct 4, 2021     

This app is amazing 👌 so I 100 percent recommend downloading it but i'd Like it even more if they'd add liquid nitrogen (Best game ever!!!!!!)

Dan. K. Feb 8, 2020     

Needs more elements that are actually on the periodic table.
