Fun and insanely creative The great thing about this puzzle game is its simplicity and its level designs. It is easy to understand and paced well, which make the messy levels even more fun. Most importantly, each level set is themed, and there is incredible aesthetic in how some of them are designed, so it never feels stale. Levels aren't added frequently, but when they are, you can expect them to be top-notch quality. This in my opinion is what separates this game from the rest of the batch.

Great puzzle game! I loved this game. It starts out easy but gets quite challenging as you get different types of blocks. Its ad-free and the in-app purchases are for hints only, it's good when developers choose user experience above making money. Definitely recommended if you like puzzles.

Entertaining logic game with plenty of challenge, but surprisingly short for as many puzzles as there were (which is why it's not a five star game). Tore through every one in a handful of hours total play, even with sparse use of hints.. Add-on puzzle packs would make this even more addictive.

Bug or cheap attempt to get in game purchases I have had this app since I got a smartphone back in about 2008 or 2009 and when completing the different puzzle types would be awarded with a couple hints if needed. Recently an update was applied and that is gone idk if it is just a bug but it is VERY disappointing.

Not fun, poorly made Sometimes you cant even see the target properly because a block is in the way, and the levels are too small so gets cramped. And ive seen other apps that use the same concept and are WAAAAY better/more fun.

Quality game but some puzzle flaws This game is aesthetically pleasing and has a great interface. I'm only a few packs into the game so my review may be innacurate but the boards only allow so many moves therefore making solving the puzzles markedly easier.

Radius Impact who the hell do u think u are?!?! just because u are apparently good in this game what does thst mean? nothing. if u was as inteligent as you claim u wouldnt feel the need to brag about it. And also u callin this friend of yours stupid? why are u friends with him then fool?

You ain't gonna believe this.... I'm giving this 5 Stars just to start with. I haven't even played it. Why you ask? I have this kind of mental thing. I don't know if I'm crazy or what. I draw imaginary straight lines with my eyes bouncing around objects the same way this game is played. My nipples are hard just waiting to try this thing. It's exactly what I do everyday and have been doing every day for years. This is like a dream come true!

A brilliant little puzzle game Simple concept, yet very challenging. This game is ad free (always good), instead gaining its well-earned money by requiring pay for additional hints. There are many levels to choose from, each pack coming with a range of the difficulty and you are reward a certain number of free hints for each pack you finish! My only complaint that keeps this game from getting a 5 is the lack of any kind of level editor, as this is the exact type of game that benefits greatly from that sort of thing.

Very good, but want addition I want to be able to flag the tiles with different colors (at least 3 colors). That way you can flag possible tile or the impossible one, just like minesweeper

Great app!! Defies laws of optics though 😂 n_i*sin(theta_i)=n_t*sin (theta_t)...transmitted beam angle will be different than the incident beam, since the refraction coefficient of glass is different than that of air. Just messing around, only because we just went over this 😂

Memories I first heard of this game in 6th grade. My best guy friend, a HUGE nerd, showed me. I thought I could never do it. By 7th grade everyone had it lol so I downloaded it. Ever since I've been addicted

Fun! It reminds me of a reflecting lasers game for Windows 3.1.1 for Workgroups back in the 90s! I loved that and I'm loving this. Buying hints is a great idea for making in game money from dumb people, and it's genius! Haha

Best addictive game of all times. I didn't know it's adfree... I use adblockers... This leads me to wanting to donate. How can I? I passed all the levels and didn't use any hint. BTW... I need more levels.

Requires a lot of thinking If you're looking for mindless, numbing puzzle matching, you're wasting your time. This is a well thought out puzzle game that requires critical analyzing of each level, I'm still stuck on the same puzzles I was years ago when I started playing. A great mobile game, don't pass this one up.

An addictive little game that you can waste hours on, five minutes at a time. It's perfect because you can play at your own pace, stop anytime, then pick it up again right were you left it. I have a couple of requests to make it a bit easier on the harder puzzles. I would like to see different colored lasers when there are two (or more if there are that many) and perhaps a pulse that travels down the laser from the source. On the complicated puzzles, it's sometime hard to keep track of what is bouncing where and I end up moving a mirror because I thought the laser was coming from one direction (or beam) when it was coming from another. But these are minor quibbles that don't affect the play-ability, or addictiveness, of the game. Great job!

Challenging. A lot of ad free puzzles. Sometimes hints are wasted because it places a reflector where you already had one.

An enjoyable puzzle app. This was an app that was just what I was looking for. An enjoyable app, if I wanted something that would ultimately challenge my spatial awareness and mental agility to the utmost limits I'd have climbed everest. This app in my humble opinion is one I will definitely keep. My thanks to the creator...

Very addictive. One of my favorite puzzle games. Good ranges of easy to hard and there are multiple 'worlds' which makes it easy to jump around if you get stuck.

Galaxy S III Great App!!!!!! Can't stop playing! Have to really, really think about where you are going to put the blocks to deflect the lazer! And the best of all....IT'S AD FREE!!!

Challenging puzzle game I enjoyed the challenges of solving each puzzle with the innovative collection of blocks. The developers have designed some really great levels. Plus it is ad free which is a great bonus.

Fantastic! A great puzzle game, mentally challenging and creative in using geometry principles of angles and mixing it with physics of different materials, absolutely deserved 5/5 stars! I would gladly pay for more levels.

Very challenging Among the best puzzles. Graphics are pretty, essential and intuitive. Level variety is high. Difficulty varies gradually but immensely. Great game

Love it And Fun I love this game it is challenging and I love the effects. The levels are so fun and I love that you can switch to so many levels. Download this game or you are a loser!

I love it At first when I downloaded it it was boring..... But now it is awesoooooooooooooome🇩🇰🇩🇯🇩🇰👏👏👏👏👏 with all these updates. Also very challenging

Pretty Much Boring I didn't find this game to be interesting. Just a lazor show. Barely make your head working.

Brilliant! Easy to learn the rules, but challenging. Graphically beautiful. @Developers: imagine a 3D laser shooting game. Diabolical!

Simple and awesome puzzle game This game is simple, has no ads and absolutely challenging. More fun if you've some knowledge of physics

Very challenging Finished every level without using any hints, some took days to solve, but it is a very good game, I can only recommend

Nice game Very nice game that gets you thinking. There is a variety of levels and it is ad free which is a huge plus.

No privs? Yes please. Too bad you can't filter on that category

Beautifully crafted game Loved every bit of it! It's simple but difficult. Try solving them in your head, without moving anything.

Fantastic game I just love this game. So well thought across levels. It's very apparent how much efforts the developers have put into this game. Well done!

Difficult to comprehemd at first Now I have finally worked out what to do I like it. Thanks.

Its okay... Bit repetitive and dull aftrr a while. I also paid for 20 more hints (I have the receipt, in duplicate) and yet my game still says 0 hints left?! Didnt want to post this here but I couldn't find a way to contact the developers.

Not a very well thought out game. Repetitive and similar to all others out there.

This game isn't that challenging if you know a little something about physics.. I got 14 hints that won't be used & 5 hard levels & 2 medium levels all completely done in a half hour not each. I don't memorize patterns I figure them out & make them. I just use this 2 see how much more some people are limited with their brain, it didn't even take me 10mins to solve the first part of the last level, about 6mins 2be exact. I skipped the beginning levels, a friend of mine thought they got the hang of the level next 2 the last level & quit when they couldn't figure out the obstacle. I solved the same part they failed on in 5mins. To think of the social filtering process gone wrong & manipulation in the world.. 2 be born into a bad section makes life vain!¦[

Nice Iterative Puzzle The puzzle makes your mind to find most of the permutation! I hope developer will add more puzzles to it...till now all levels have been completed!

To easy All you have to do is find the first and then follow the line if you had a max amount of moves it would be better

Great game Genuine developer, No adds, no unnecessary permissions.
